GPR-42 Black Toner Cartridge

The Canon 4791B003 GPR-42 is a genuine OEM toner cartridge engineered specifically for compatible Canon printers. It delivers consistent black output for professional documents and photos. This new unit is built to maintain the high print standards expected from original Canon supplies.

Offices needing reliable high-volume mono printing

This cartridge suits workgroups that require dependable quality and a yield of up to 34200 pages without frequent changes. It is not for users who need colour output or anyone whose printer model does not accept the GPR-42 series. Buyers seeking refilled or third-party alternatives should look elsewhere.

34200-page rated yield

The headline specification is the rated capacity of up to 34200 pages, which determines how long the cartridge lasts before replacement. This figure lets IT managers plan supply cycles and cost per page accurately. Verify that your device lists the GPR-42 as a compatible supply before ordering.

Questions about this item

How do I install the Canon GPR-42 toner cartridge without triggering a low-toner error?

Power off the printer, open the front cover, pull out the old cartridge, gently rock the new GPR-42 five times, remove the sealing tape completely, slide it in until it clicks, then close the cover before powering on.

Which part will need replacement after I print the rated 34200 pages?

The GPR-42 cartridge itself is the only consumable rated for 34200 pages; drums, fusers and waste-toner boxes are separate maintenance items with their own service intervals.

What print-quality issue appears first when I run long continuous jobs with this cartridge?

Extended runs can cause toner depletion inside the GPR-42, leading to faded text or light streaks across the page before the 34200-page yield is reached.
