Compatible HP 970 & 971 Refillable Cartridges with 100ml Tank and Resettable Chip

Finding a reliable and economical ink solution for your HP Officejet Pro printer is a common concern. These compatible HP 970 and 971 series cartridges are designed to work with several popular Officejet Pro models, including the X451dw, X551dw, and X576dw. They arrive as empty, high-capacity tanks holding 100ml of ink space, offering a substantial supply that can reduce the frequency of changes compared to standard cartridges. Each unit includes a resettable chip, which communicates with your printer to allow operation. Available in the core printing colours—black, blue, red, and yellow—you can purchase them individually to replace specific depleted cartridges in your printer's colour lineup.

Features and Construction

This product is built as a direct physical and electronic replacement for the original HP 970 and 971 cartridges. Its primary features focus on capacity, compatibility, and reusability to provide a practical alternative for home office or small business printing.

Material and Build

The cartridge is constructed from durable plastic, forming the main ink tank body. The key functional component is the integrated, resettable electronic chip. This chip is essential as it allows the printer to identify and accept the cartridge, preventing error messages and enabling normal printing functions. The design is specifically engineered to fit precisely into the cartridge bays of the listed HP Officejet Pro printer models.

Size and Practical Fit

Each cartridge has external dimensions of 15.0 cm in length, 10.0 cm in width, and 5.0 cm in height. This standardised size ensures a correct physical fit within the printer. The 100ml internal capacity is a significant volume, intended to hold much more ink than a typical original equipment manufacturer (OEM) cartridge. This large capacity is the core differentiator, aiming to provide more printed pages per fill and lower the cost per page over time.

Uses and Placement

These cartridges are suited for users who print regularly and seek to manage their ink costs effectively. They are a fit for both document printing and colour graphics where the listed HP printers are used.

Event or Professional Use

For small businesses, home offices, or educational settings that rely on the HP Officejet Pro X451, X551, or X576 series printers, these compatible cartridges can be a cost-saving component. The high 100ml capacity means fewer interruptions for cartridge changes during high-volume printing tasks, such as producing reports, marketing materials, or student assignments. Being able to purchase individual colours allows for targeted replacement, only swapping out the colour that has run out.

Everyday Home Use

For household printing needs—including school projects, personal documents, and family photos—these refillable cartridges offer a way to maintain printer functionality without frequently purchasing new OEM cartridges. The resettable chip feature suggests the cartridge shell can be reused multiple times after refilling, aligning with a more sustainable approach to printing by reducing plastic waste from disposable cartridges.

Benefits and Buying Value

The value of this product lies in its potential for cost reduction and extended printing intervals compared to using only original manufacturer cartridges.

Reuse and Low Maintenance

The resettable chip is central to the product's reuse proposition. After the initial 100ml of ink is depleted, the chip can often be reset (using methods described by the supplier or found online), and the tank can be refilled with compatible ink. This cycle can potentially be repeated, making the physical cartridge a long-term component. It requires the user to handle ink refilling, which is a simple maintenance step compared to the cost of a brand-new cartridge.

Why Choose This Product

Choose these compatible cartridges if you own one of the specified HP Officejet Pro printers and are looking for a high-capacity, refillable alternative. They are a practical choice for users comfortable with the refilling process who want to decrease their printing expenses. The package of three cartridges per colour provides a backup supply, ensuring you have a replacement ready when one runs empty. It is important to use high-quality, compatible ink to ensure optimal print results and printer health.
