In this guide
An HP ink refill bottles kit can keep an inkjet printer supplied with ink without replacing a full cartridge each time. The right kit depends on whether your printer uses refillable cartridges, a continuous ink supply system, or a built-in Smart Tank, as well as which cartridge numbers and ink formats your device supports.
We compared the ten featured products by examining stated compatibility, bottle and cartridge volume, included accessories, refill method, ink type, claimed page yield, and customer rating. The guide covers both cartridge-refill kits with syringes and direct-fill bottle sets designed for compatible HP Smart Tank and Ink Tank printers.
Each review identifies the product's strongest benefits, practical limitations, and ideal user, helping you narrow the field before purchasing. Product availability, ratings, and prices can change over time, so confirm the current listing and printer compatibility before placing an order.

1. Aomya Cartridge Refill Kit – Best Overall Cartridge Refill
Aomya Cartridge Refill Kit
400ml total ink
Four 100ml bottles
Black cyan magenta yellow
Broad cartridge support
The Aomya Printer Ink Refill Kit is a four-color cartridge refill solution for HP 60, 61, 62, 63, 64, 65, 67, and several other listed cartridge families. It carries a 4.2 rating and stands out for offering a balanced 400ml package with 100ml bottles of black, cyan, magenta, and yellow ink.
Pros
- Four full refill colors
- Broad cartridge compatibility
- Useful for CISS systems
- Balanced 400ml capacity
Cons
- Cartridge syringe refilling
- Chip recognition may vary

Its compatibility extends beyond ordinary refillable cartridges to refillable cartridges and CIS or CISS systems. Aomya states that the ink is designed to produce vivid colors, accurate output, and smooth ink dots, making it suitable for routine documents, graphics, and general home-office printing.
The main tradeoff is that this is a cartridge-refill approach rather than a direct Smart Tank bottle system. Refilling requires compatible cartridges, careful syringe use, and suitable refill access. Printer recognition can also depend on cartridge chips and their remaining condition, so this kit is not ideal for users expecting a fully sealed, plug-and-play tank refill.
This is a strong choice for owners of older or mixed HP cartridge setups who want all four colors in one reasonably balanced package. Confirm the exact cartridge number, inspect the cartridge before refilling, and avoid allowing a chip-equipped cartridge to sit completely empty.
Balanced Four-Color Refill Package
Four 100ml bottles provide equal-volume ink options for black and the three standard colors. That makes the kit practical for maintaining a complete refillable cartridge set without separating purchases by color.
Useful CISS and Cartridge Support
The stated support for refillable cartridges and continuous ink supply systems broadens its appeal. It can suit users who maintain an established tank setup rather than buying a complete new printer.

2. JETSIR Dye Refill Kit – Flexible Multi-Cartridge Refilling
JETSIR Dye Refill Kit
500ml total ink
Five 100ml bottles
Two black bottles
Includes four syringes
The JETSIR Dye Ink Refill Kit is a five-bottle set designed for a wide collection of HP cartridges, including 950, 951, 952, 902, 901, 60, 61, 62, 63, 21, 22, 564, 920, 940, 932, 933, 711, 970, 971, and several additional models. Its 4.1 rating reflects a practical package built around cartridges, syringes, and repeated refilling.
Pros
- Largest color-bottle package
- Extensive cartridge list
- Complete refill accessories
- Clear refill instructions
Cons
- Dye ink only
- Syringe workflow required
We may earn a commission when you buy through this link, at no additional cost to you.
The kit contains five 100ml dye-ink bottles: two black plus one each of cyan, magenta, and yellow. It also includes four syringes, refill tips, sealing plugs, and instructions, allowing users to draw ink, inject it gradually, and close the refill opening securely.
Compared with many direct-fill sets, this product requires more hands-on work and suitable refillable cartridges. It is also dye-based, which may be a limitation for users seeking the text density and water resistance commonly associated with pigment black ink. Overfilling or injecting too quickly can cause leakage.
Choose this kit if you own a refillable HP cartridge or CISS setup and value broad model support plus a complete accessory package. New refillers should work slowly, seal each cartridge properly, and allow it to rest before printing.
Complete Refilling Toolkit
Syringes, tips, plugs, and written instructions remove the need to assemble a separate refill setup. The additional black bottle also provides useful reserve capacity for text-heavy printing.
Broad Cartridge Family Support
The unusually long compatibility list includes classic 60-series, 950-series, 900-series, 21-series, and other cartridges. Buyers should still identify the number printed on their cartridge before ordering.

3. JoyPrinting Wide Compatibility Kit – Detailed Refill Support
JoyPrinting Wide Compatibility Kit
500ml total ink
Five 100ml bottles
Four included syringes
Disposable gloves included
The JoyPrinting Ink Refill Kit targets HP 67, 67XL, 62, 63, 64, 65, 68, 60, 61, 910, 950, 951, 952, 962, 923, 936, 902, 932, and 933 cartridges. It has a 4.1 rating and distinguishes itself with detailed refill guidance, disposable gloves, four syringes, and a 500ml total volume.
Pros
- Wide cartridge model coverage
- Purification process described
- Gloves improve cleanup
- Useful for CISS systems
Cons
- Empty-chip recognition warning
- No direct-fill tank bottles
We may earn a commission when you buy through this link, at no additional cost to you.
The manufacturer states that the ink is processed through three to five rounds of high-molecular nanofiltration to remove impurities, salts, and metal ions. It also claims laboratory testing for stable color and smoother ink flow, which are relevant considerations for printers using refillable cartridges or CISS systems.
Its most important warning concerns cartridge chips. A cartridge that has already been completely depleted may be rejected after refilling because its original chip can lock or report empty. The product should therefore be used before the cartridge reaches a completely empty state, and it is less suitable for users who want effortless tank refills.
This kit is best for established cartridge-refill users with compatible HP models and functioning chips. Its detailed accessories, instructions, and purification claims make it more attractive than a basic ink-and-syringe set, provided you follow the chip-related guidance.
Filtration-Focused Ink Formulation
The stated multi-stage nanofiltration is intended to support smooth ink flow and reduce clogging. That makes cartridge condition and routine printhead maintenance particularly important.
Refill Before the Cartridge Is Empty
Refilling while some ink remains can help avoid the permanent chip-lock problem highlighted by the manufacturer. Users with frequently depleted cartridges should account for this limitation.

4. Inkgens 31 32XL Set – Balanced Tank Refill
Inkgens 31 32XL Set
465ml total capacity
165ml black bottle
Three 100ml colors
Auto-stop bottle design
The Inkgens 31 32XL Ink Bottle Set is designed for HP Smart Tank 7600, 7602, 7300, 7301, 7001, 5000, 5101, 5102, 6000, 6001, 651, and 551 printers. It earns a 4.5 rating and includes a 165ml black bottle plus 100ml cyan, magenta, and yellow bottles.
Pros
- Large black ink bottle
- Anti-leak auto-stop design
- Broad Smart Tank coverage
- Gloves and opener included
Cons
- Mixed pigment and dye inks
- Requires nozzle cleaning when switching
We may earn a commission when you buy through this link, at no additional cost to you.
An auto-stop design allows the bottles to connect directly to the refill inlet without squeezing, helping reduce spills. The manufacturer also states that the black 32XL bottle can produce up to 19,000 pages, while each 31 color bottle can produce up to 10,000 pages under stated 5% A4 coverage conditions.
The black bottle is pigment ink, while the color bottles are dye ink. That distinction matters if your printer previously used a different formulation, because switching without cleaning the cartridge and nozzles may affect output. Users should not view the stated page figures as guaranteed results because coverage, images, and settings can significantly change consumption.
This is a well-rounded option for compatible Smart Tank owners who want a full four-color refill and extra black capacity. It is especially attractive for users who value the direct-fill format, simple bottle connection, and a substantial black bottle.
Direct-Fill Convenience
The auto-stop nozzle is designed to stop flow when the tank is full, reducing the need to estimate bottle volume. It creates a cleaner routine than transferring ink with a syringe.
High Black-Capacity Bottle
The 165ml black bottle gives text-heavy users more reserve ink per refill than the 100ml color bottles. The manufacturer lists a particularly high black page estimate under controlled coverage.

5. 31 32XL Five-Pack Set – Extensive Smart Tank Support
31 32XL Five-Pack Set
465ml total capacity
One 165ml black bottle
Three 100ml color bottles
Broad Smart Tank coverage
The 31 32XL Five-Pack Set is a direct-fill ink solution for a large selection of HP Smart Tank, Smart Tank Plus, Smart Tank Series, and Ink Tank Series printers. It has a 4.2 rating and provides a 165ml 32XL black bottle with 100ml cyan, magenta, and yellow 31 bottles.
Pros
- Extensive printer model list
- High-capacity black bottle
- Simple direct-fill operation
- Supports many tank families
Cons
- All inks described as dye
- Cleaning advised before refilling
We may earn a commission when you buy through this link, at no additional cost to you.
Compatibility includes Smart Tank 5000, 5101, 7602, 5103, 6001, 5003, 5100, 6003, 7603, 7001, 7301, 7002, 5102, and 7302 models. The list extends to Smart Tank Plus 651, 551, 555, 557, 559, 655, 617, 570, 571, 578, 600, 615, and 675, plus numerous 450-series and Ink Tank models.
The manufacturer says all bottles in this set are dye inks, which differs from OEM black pigment ink. It specifically recommends cleaning printer heads before refilling and warns against mixing with OEM pigment black because differences can affect print quality and performance.
This is a practical choice for users with one of the many listed tank printers, particularly if model confirmation is easy. It is less suitable for those who specifically want to retain pigment black performance or avoid a cleaning cycle after using a different ink type.
One of the Broadest Model Lists
Compatibility spans current-style Smart Tank numbers, Smart Tank Plus models, 450-series units, and Ink Tank series. The printer's model number and required ink numbers should be checked together.
Plan Ink-Type Changes Carefully
Because the listed formulation is dye-based, users moving from pigment black should follow the cleaning guidance. Keeping one ink type in the system can also reduce print-quality surprises.

6. HP 31 Color Ink Bottles – Refined Spill-Free Color Refill
HP 31 Color Ink Bottles
Three 100ml color bottles
Smart Tank Plus support
Approximately 8,000 pages
Auto-stop bottle connection
The HP 31 Cyan, Magenta, Yellow Ink Bottles three-pack is a color-focused refill set for Smart Tank and Smart Tank Plus printers. It has a 4.8 rating, one of the highest in this guide, and is built around the familiar 9C228AN-style HP 31 color bottle format.
Pros
- Highest listed rating
- Simple spill-free refilling
- Broad supported tank range
- Strong stated color yield
Cons
- Color bottles only
- Black ink not included
We may earn a commission when you buy through this link, at no additional cost to you.
The manufacturer lists support for Smart Tank Plus 570, 551, 578, and 651, along with Smart Tank 5103, 5104, 6001, 5102, 5101, 7301, 5000, 5100, 7602, 6002, and 7302. Bottles plug directly into the ink tank and drain without squeezing.
This premium-oriented package is centered on convenience and a refined refill process. The spill-free, no-squeeze design minimizes the risk of drips, while the stated approximate yield of 8,000 color pages provides a useful capacity indication. The package does not include black ink, so users still need a separate HP 32 or 32XL black bottle.
Choose this set when color printing is the priority and your printer appears in the compatibility list. It is especially suitable for people who want straightforward bottle refills without syringes and want a high-rated color-only package.
Mess-Free Bottle Connection
The bottle docks into the tank inlet and allows ink to drain, requiring no squeezing. This is a cleaner, more approachable process than transferring ink into a removable cartridge.
Color Printing Without a Full Kit
A dedicated three-color set is useful when cyan, magenta, and yellow are low but black remains adequate. It avoids buying unnecessary black ink while preserving convenient direct refills.

7. Topcolor 31 32XL Set – Sealed Four-Color Refill
Topcolor 31 32XL Set
465ml total capacity
One 165ml black bottle
Three 100ml color bottles
Aluminum-sealed bottle tops
The Topcolor 31 32XL Ink Bottle Set is a four-color direct-refill package for HP Smart Tank and Smart Tank Plus printers. It carries a 4.4 rating and includes one 165ml 32XL black bottle plus one 100ml 31 bottle each of cyan, magenta, and yellow.
Pros
- Four full-size refill colors
- Sealed tops reduce leakage
- Extensive tank model support
- Quick-drying ink claim
Cons
- Mixed ink formulations
- Compatibility requires verification
We may earn a commission when you buy through this link, at no additional cost to you.
Its stated compatibility covers Smart Tank 5101, 6001, 5000, 7602, 7301, 7001, 5102, 5103, 7603, 5100, 5003, and 6003 models. Smart Tank Plus 651, 551, 555, 557, 559, 655, 617, 570, and 571 are also listed, along with older 450-series, Ink Tank series, and DeskJet GT-5810, GT-5820, and GT-5822 printers.
The manufacturer emphasizes a smooth, even ink formula that is intended not to clog or fade, and it notes that the transparent tops are sealed with aluminum film for transport. Stated output is 9,000 pages for the 32XL black bottle and 8,000 pages for each 31 color bottle, based on 5% coverage.
This is a well-rounded set for a compatible tank printer. The sealed bottle tops and large color bottles are helpful features, while the extensive model list reduces the chance of missing a relevant printer. Buyers should still confirm that their model uses 31 and 32XL inks.
Transport-Friendly Sealed Bottles
Aluminum sealing film and transparent bottle tops help protect the ink during storage and shipping. Opening only the required bottle can reduce exposure of the remaining colors.
Full-Color Starter Package
The set includes a large black bottle and all three standard colors. That makes it a practical way to replenish every tank after setup or when several colors approach depletion.

8. JetSir 31 32XL Four-Pack – Practical Value Refill
JetSir 31 32XL Four-Pack
350ml total capacity
140ml black bottle
Three 70ml color bottles
Four refill colors
The JetSir 31 32XL Ink Bottle Refill Kit is a four-pack for HP Smart Tank, Smart Tank Plus, Ink Tank, and supported DeskJet GT all-in-one models. It earns a 4.7 rating and provides 140ml of black ink plus 70ml each of cyan, magenta, and yellow.
Pros
- High customer rating
- Compact four-bottle package
- Broad Smart Tank support
- Includes technical support
Cons
- Smaller color bottles
- Lower total volume than rivals
We may earn a commission when you buy through this link, at no additional cost to you.
Compatibility includes Smart Tank 7301, 7001, 7602, 6001, 5000, 5101, 450, 455, 457, 517, 532, 502, and 514. The list also includes Smart Tank Plus 551, 555, 557, 559, 651, 655, 617, 570, and 571, Ink Tank 310 through 419 models, and DeskJet GT-5810, GT-5820, and GT-5822.
This set has less total ink than the larger five-bottle and multi-pack options, with each color bottle holding 70ml. The trade-off is a more compact package that may be more practical for users with limited storage, moderate print volume, or a need to refresh all colors without acquiring a large multipack.
Choose it for straightforward tank refilling across a wide range of supported models. The 4.7 rating, useful compatibility coverage, and lower overall volume make this a compelling value-oriented choice for regular home printing.
Compact Four-Color Package
The smaller 70ml color bottles reduce shelf space and may be easier to handle. This format suits owners who prefer frequent, moderate refills over maintaining a large ink reserve.
Strong Coverage for Home Printers
The model list covers several Smart Tank, Smart Tank Plus, Ink Tank, and DeskJet GT families. Checking the exact model is still essential because similar-looking printers can use different ink systems.

9. Osinkjet 31 32XL Multi-Pack – High-Volume Color Supply
Osinkjet 31 32XL Multi-Pack
Two black bottle sets
Three color bottle sets
Up to 43,000 pages
Auto-stop refill design
The Osinkjet 31 32XL Multi-Pack is a substantial refill bundle with two 32XL black bottles and three sets of 31 color bottles. It has a 4.7 rating and is intended for high-volume users of compatible HP Smart Tank 5000, 6000, and 7000 series or Smart Tank Plus 500 and 600 series printers.
Pros
- Large multipack quantity
- Two black refill bottles
- High stated total yield
- Auto-stop bottle design
Cons
- Multiple color sets included
- Mixed pigment and dye inks
We may earn a commission when you buy through this link, at no additional cost to you.
The manufacturer states that the package can produce up to 43,000 pages: 19,000 from the 32XL black bottle and 8,000 from each 31 color set, based on 5% coverage. The exact quantity and arrangement of color sets should be confirmed on the listing, as the product data describes three 31 ink bottle sets.
An auto-stop design is intended to prevent spills and simplify connection to the tank. The package also includes a pair of gloves and a bottle-cap opening gadget. As with other options, the stated yield will vary with image density, text coverage, duplex printing, and other usage patterns.
This multipack is best suited to busy home offices, schools, or small workgroups that print frequently and have suitable storage. It offers a larger reserve than the four-bottle sets, but buyers should consider whether they can finish multiple sets before the color ink ages.
Substantial Ink Reserve
The two black bottles and repeated color sets support a lower replenishment frequency. That is useful for environments where printers run continuously or cartridge changes are inconvenient.
Distinct Ink Formulations
The manufacturer identifies 31 ink as dye-based and 32XL black as pigment-based. Changing between formulations may require cleaning, and the stated color benefits should be evaluated within that context.

10. 31 32XL High-Yield Set – Maximum Capacity Refill
31 32XL High-Yield Set
Five-bottle high-capacity set
Two black bottles
Three color bottles
Up to 52,000 pages
The 31 32XL Ink Refill Bottle Set is a five-bottle package for HP Smart Tank printers, with a stated rating of 4.8. It combines two black bottles with cyan, magenta, and yellow bottles and is positioned as a high-capacity option for frequent document, presentation, and photo printing.
Pros
- Highest stated total yield
- Supports 60-plus models
- Leak-closing refill nozzle
- Black pigment and dye colors
Cons
- Requires model-list verification
- Large package storage needs
We may earn a commission when you buy through this link, at no additional cost to you.
The product data states compatibility with more than 60 HP Smart Tank models, including 5000, 5101, 6001, 7001, 7301, and 7602. It claims up to 52,000 pages total: 32,000 pages from two black bottles and 11,000 pages from each color bottle, all based on 5% coverage.
The auto-closing nozzle is designed to prevent drips, and the bottle is placed directly on the tank inlet without squeezing. Pigment black and dye-based colors are used to support crisp text and vivid color output. The formula is described as water-soluble and chemical-free, while its clog-resistant composition is intended to protect printheads during longer idle periods.
This is the strongest choice in the guide for high-volume users who find a listed model and need a large reserve. Its main drawback is the need to verify the comprehensive compatibility list and store multiple bottles, but the refill system itself is straightforward and mess resistant.
Largest Stated Output
The two-black-bottle configuration creates the highest listed total yield in this comparison. It is well suited to organizations that print many text pages and want fewer replenishment interruptions.
Automatic Ink-Flow Control
The auto-closing nozzle is intended to reduce spills and drips during direct filling. The refill process avoids syringes, making routine tank maintenance less demanding.

Buying Guide – How to Choose the Best HP Ink Refill Bottles Kit
Choosing an HP ink refill kit starts with identifying your printer's refill architecture, required cartridge or bottle numbers, and preferred refill method. Capacity, ink type, included tools, and maintenance requirements then determine which package offers the most useful long-term fit.
Printer and Ink Compatibility
Compatibility involves more than recognizing the HP brand. Some products refill removable 60, 61, 62, 63, 67, and 950-series cartridges with syringes, while others pour directly into built-in Smart Tank or Ink Tank reservoirs. Check the printer model number, the cartridge label, and the ink numbers listed on the product before purchasing.
Match the exact model and ink numbers rather than assuming every HP printer accepts the same refill system.
Refill Method
Cartridge kits generally include 100ml bottles, syringes, tips, and sealing plugs. They are useful for refillable cartridges and CISS systems, but require a compatible refill opening and careful manual transfer. Direct-fill bottle sets connect to the tank inlet, usually without squeezing, and are generally less involved for routine Smart Tank maintenance.
Choose syringe refilling for established cartridge systems and direct fill for built-in tanks.
Ink Type and Mixing
Pigment black and dye-based color inks have different characteristics, and several sets also use dye-based black. Switching formulations can affect color, sharpness, and flow. Products that mix formulas often recommend cleaning the cartridge or printhead before changing inks to reduce contamination and print-quality issues.
Use one compatible formulation consistently and follow the stated cleaning guidance when switching.
Total Ink Capacity
Total volume ranges from compact four-color packages of about 350ml to larger sets with repeated black and color bottles. Larger capacity reduces refill frequency but requires more storage and may be excessive for a lightly used printer. Examine the volume of each bottle rather than relying only on the total figure.
Select a volume that matches your print volume and available storage.
Included Refill Tools
Cartridge-refill packages vary considerably in their supporting tools. A useful set includes appropriately sized syringes, refill tips, sealing plugs, instructions, and gloves. Direct-fill packages may instead include bottle-cap opening tools, while auto-stop nozzles are built into the bottles. These accessories influence cleanup, convenience, and the likelihood of a smooth first refill.
Favor a complete, clearly explained kit for beginners or cartridge maintenance.
Page-Yield Claims
Page estimates are generally based on 5% coverage on A4 paper. They can provide a useful comparison, but they do not predict identical results for every document. Dense photos, full-page graphics, high-resolution settings, and frequent color use can consume ink much faster than standardized text coverage.
Treat yield claims as comparative estimates, not guaranteed page counts.
Spill Prevention
Direct-fill bottles may use auto-stop or auto-closing nozzles that help limit spills. Cartridge kits rely on sealing plugs and careful injection technique. Regardless of the format, keeping bottles upright, opening only one container at a time, and working over a protected surface can prevent unnecessary mess.
Look for sealed bottle tops and deliberate, mess-resistant delivery systems.
Support and Warranty
Manufacturer support can be valuable when a printer is not listed, a bottle arrives damaged, or ink flow behaves unexpectedly. Some listings explicitly offer technical support, exchanges, or after-sales assistance, while others provide only general customer service. Check the current listing for return terms and contact information before buying.
Prefer sellers that clearly explain compatibility and defective-product handling.
How to Use and Care for Your HP Ink Refill Bottles Kit
Begin by confirming the printer model, required ink numbers, and the product's compatibility instructions. For a direct-fill tank, clean the nozzle and cap, remove the tank's protective seal, and prepare a clean workspace. For cartridge refilling, inspect the cartridge, confirm that it has refill access, and ensure its chip remains in working condition before adding ink.
Open one bottle at a time, remove its seal, and fill the cartridge gradually with the included syringe. Direct-fill users should align and secure the bottle on the tank inlet, allowing the auto-stop mechanism to regulate the flow. Do not force a bottle that does not fit, avoid overfilling, and promptly replace a cap after each refill.
After filling, seal every cartridge refill hole or close the tank cap, then let the ink settle briefly before running a test page. If output is streaked, dull, or uneven, consult the printer's cleaning process and the ink manufacturer's guidance. Store bottles tightly sealed, upright, and away from temperature extremes, and avoid mixing formulations unless the product specifically permits it.
Frequently Asked Questions
Can HP ink refill bottles be used in every HP printer?
No. HP printers use several different ink and cartridge systems, and a bottle that fits one tank model may not fit another. Check the exact printer model, cartridge or bottle number, and the manufacturer's compatibility list before ordering. Cartridge syringe kits and direct-fill Smart Tank bottles are not interchangeable.
Are 31 and 32XL refill bottles the same?
No. HP 31 is generally a color ink format, while 32 and 32XL are black formats with different capacities. Many kits combine one black bottle with cyan, magenta, and yellow bottles. Verify both the color and the XL designation because a standard black bottle may not match a printer designed for 32XL.
Why does a refilled cartridge show as empty?
Some original cartridge chips lock or report empty after the cartridge has been fully depleted. Refilling cannot always reset that condition, so a chip-equipped cartridge may remain unrecognized. Refill before it is completely empty, inspect the cartridge for damage, and verify that the cartridge is refillable and compatible with the ink system.
Can I mix pigment black and dye-based refill ink?
Mixing formulations can affect color, sharpness, flow, and printhead performance. Several products in this guide use pigment black and dye color, while others use dye black. Follow the ink manufacturer's mixing and cleaning instructions, and clean the cartridge or printhead when changing between formula types.
How do I refill an HP Smart Tank without spilling?
Place the printer on a protected surface, open one tank cap, remove the bottle seal, and align the refill nozzle with the ink inlet. Many compatible bottles use an auto-stop or auto-closing design, so ink flows without squeezing. Keep the bottle upright, close the tank after filling, and store the remaining bottles tightly capped.
Do the listed page yields guarantee the same number of pages?
No. The stated yields are normally based on 5% coverage on A4 documents. Photos, graphics, heavy text, printer settings, and cartridge maintenance can change actual output substantially. Use the yield figures to compare package capacity, but plan refills according to your own print mix.
What should I do if the colors look wrong after refilling?
Run the printer's built-in cleaning cycle if the manual recommends it, and confirm that the correct ink was installed in each tank. Also check whether you changed from pigment to dye or mixed different formulations. If the problem continues, contact the ink supplier or printer support before repeatedly cleaning the printhead.
Is a cartridge refill kit better than a Smart Tank bottle set?
The better choice depends on the printer. A cartridge kit is appropriate when you own refillable cartridges or a CISS setup and want to replenish individual cartridges. A direct-fill bottle set is usually easier for a compatible Smart Tank or Ink Tank printer because it avoids syringe transfer and sealing plugs.
Final Thoughts on Choosing the Best HP Ink Refill Bottles Kit
The HP 31 Color Ink Bottles stand out for a polished direct-fill experience and a 4.8 rating, while the 31 32XL High-Yield Set offers the largest stated capacity for heavy users. The JetSir four-pack provides a practical, compact option with a 4.7 rating and broad Smart Tank compatibility.
Prioritize exact printer and ink-number compatibility before considering capacity or yield. Choose syringe kits for refillable cartridges and CISS systems, direct-fill bottles for built-in tanks, and pay attention to pigment versus dye formulations. Refill tools, anti-spill features, and included instructions can make a substantial difference for first-time users.
Ratings, product availability, and prices change over time, so review the current listing before purchasing. Confirm the printer model, read the ink-type guidance, and compare the package contents with your printing volume to find the most suitable refill solution.
