Laser Tek Services 4PK High Yield Toner Refill Kit for HP 507A Cartridges

Four-Pack High-Yield Refill Kit for HP 507A

This four-pack refill kit supplies toner powder and replacement chips for HP 507A black, cyan, magenta and yellow cartridges. It is designed for owners of LaserJet Enterprise 500 Color M551, M575 and M570 series printers who want to reuse original shells. The kit provides enough material for multiple refill cycles per cartridge. Small offices and home users benefit from lower cost per page.

Refill Process With Included Chips

Each colour bottle comes with a dedicated smart chip that resets the printer’s page counter after refilling. Step-by-step instructions guide the user through opening the cartridge, pouring toner and seating the new chip. The patented powder formulation reduces spillage, but care is still required to avoid contaminating the waste-toner compartment. Cartridges worn beyond three cycles may develop mechanical faults that toner cannot fix.

Yield Limits at Five-Percent Coverage

The quoted page yield assumes a standard five-percent page coverage across all four colours. Heavy graphics, solid fills or frequent duplex printing will reduce actual output well below the rated figure. Environmental factors such as humidity can also affect toner flow and density. Users printing mostly dense colour documents should expect fewer pages per refill than the laboratory rating suggests.
