31 32XL Ink Refill Bottles for HP Smart Tank — 165ml Black + 80ml Colour Set

What this is and what it’s for

The 31 32XL ink refill bottles are a multi‑pack designed for HP Smart Tank printers across a wide range of models. It includes two 165ml black bottles and three 80ml colour bottles (cyan, magenta, yellow) plus a pair of gloves and a bottle‑opening tool. On the page yield, the black 32XL bottle is rated up to 8,000 pages, while the colour bottles together can reach around 7,000 pages for everyday printing. If you’re looking to keep a busy printer running without frequent cartridge changes, this set aims to offer a practical balance of capacity and cost per page.

How it refills and what to expect

The refills incorporate an automatic shut‑off bottle system to minimise spills and overflow during the refill process. For most users, that means fewer interruptions and less mess when topping up your HP Smart Tank. As with any refill system, it’s important to monitor the amount you pour and to avoid cross‑contamination between ink types. The black ink uses a pigment base, while the colour inks are dye‑based, the manufacturer notes that mixing different ink types can affect print stability. This is a sensible reminder to keep black and colour refills separate if you’re running a mixed supply.

What stands out (and what to temper)

On paper, the kit’s standout is the generous capacity—particularly the 165ml black bottles, which can stretch more pages between refills. The inclusion of a refill tool and gloves is helpful for a tidier operation, especially if you print a lot and want to minimise drips. However, the colours are single packs per bottle (cyan, magenta, yellow) and the total colour capacity is lower than the black, which is common in dye/ pigment style sets. If you prioritise long black print runs and reliable colour for everyday documents, this set can represent a practical middle ground. If you’re a high‑volume photo or graphics printser, you may notice the need for occasionally refreshing both black and colour supplies independently.

Who it’s for

This kit suits households or small offices with HP Smart Tank printers in the 300–7000 range that want a cost‑per‑page layout with decent page yields and a cleaner refill experience. It’s particularly appealing if you frequently print text documents and mixed colour pages, and you value a tidy refill process over chasing individual component inks from a single supplier.

Who it isn’t ideal for

If you rely heavily on photo‑quality colour or run very high‑volume colour graphics, you might want to review whether the dye‑based colour inks meet your accuracy or longevity expectations. Also, if you prefer separate colour cartridges with guaranteed interchangeability, a fixed colour cartridge set from a dedicated supplier might feel simpler. Finally, if you often print in large solid blacks, you’ll need to ensure you keep the black supply topped up to avoid interruptions.

When does it make sense to buy

This refill set makes sense when you’re aiming to reduce per‑page costs, keep downtime low during refills, and you’re printing a mix of text and everyday colour documents. The kit’s page yields are competitive for the volumes typical of home and small‑office use, and the spill‑minimising refill design helps during busy periods.

What to check before purchasing

• Confirm your printer model is within the compatible HP Smart Tank range listed (the set targets 32XL Black and 31 Colour bottles for multiple series).
• Be mindful of the ink type mix: 31 colour inks are dye‑based, 32XL black is pigment‑based, and avoid mixing different ink types for stable printing.
• Consider your usual print load: if you print heavily in colour, you may want to gauge whether your colour bottles will meet demand alongside the black supply.
• Assess whether you value the included accessories (gloves and bottle opener) for a tidier refill process.

Practical use case

Imagine a busy home‑office morning: you’re chasing QAs, printing a batch of reports with a splash of colour in graphs. With this kit, you can top up the black ink quickly and then run a thousand or so pages with the colour bottles ready to go, without swapping entire cartridges. The spill‑free design helps keep the desk tidy, which is a real plus when you’re juggling tasks.

Quick comparison (implicit alternatives)

If you want maximum simplicity with guaranteed colour accuracy, some users might prefer individual colour cartridges or a different refill system with a tighter control on dye vs pigment usage. For those who value higher page yields per refill and a more economical approach to daily document printing, this kit sits as a sensible middle ground between frequent small top‑ups and more expensive full cartridge replacements.

FAQ (typical questions you may have)

• Do I need to mix black and colour inks? No. The kit notes avoiding mixing different ink types to maintain stable printing.
• What’s the advantage of the 165ml black bottles? They offer higher page yields per refill, reducing how often you refill the black ink during busy periods.
• Are the included tools essential? The bottle‑opening tool and gloves ease refilling and help keep hands cleaner, especially if you refill often.

Is it worth it?

It’s worth it if you prioritise cost per page and a cleaner refill process for everyday HP Smart Tank printing. It may not be the best fit if your usage skews heavily towards high‑end photo output or you want absolute simplicity with a single colour supply solution. For many users, this kit represents a pragmatic compromise between capacity, price and practicality.
