Cyan refill kit for HP 645A cartridges

The Laser Tek Services cyan refill kit is designed for HP C9731A 645A cartridges used in Color LaserJet 5500 and 5550 series printers. It provides toner and a reset chip so the cartridge reports full capacity after refilling. The kit targets offices and home users who want to reuse existing cartridges rather than buy new ones.

Refill process and cartridge reuse

Each kit contains the toner and chip required for a single cyan cartridge refill. The reset chip allows the printer to recognise the refilled cartridge without error messages. Users can refill the same cartridge up to three times, reducing waste and ongoing consumable cost while keeping the original cartridge shell in the printer.

Suited for high-volume colour printing.

This kit suits environments that print regularly in colour and want to lower per-page expense by refilling HP 645A cyan cartridges. It does not fit cartridges from other HP series or third-party printers, and it is only for cyan — separate kits are needed for magenta, yellow or black.

Questions about this item

How many refill cycles can the cyan 645A cartridge handle before print quality drops?

The kit supports up to three refills of the original CF331A cartridge while maintaining sharp, consistent output.

Does the refill process generate extra heat or noise during continuous printing?

Refilling the cartridge itself adds no heat or noise; the printer operates at its normal levels once the reset chip is installed.

Which original cartridge must I already own for this cyan 645A kit to work?

You need an empty HP CF331A (645A) cyan toner cartridge to refill with this kit.
