Genuine Canon GPR-42 Black Toner

The Canon GPR-42 is an original black toner cartridge built for the imageRUNNER ADVANCE 4045, 4051, 4245 and 4251 multifunction printers. It suits offices that need consistent output from a manufacturer-supplied consumable rather than a third-party alternative. The cartridge delivers approximately 34200 pages at five percent coverage.

Sustained Print Volume

Rated at 34200 pages, the cartridge maintains stable density across long print runs without the yield drop sometimes seen with non-OEM supplies. Offices printing thousands of pages each month can rely on the rated capacity for predictable replenishment cycles. The genuine formulation reduces the risk of streaks or background toner during continuous operation.

Build Quality and Fit

As an OEM component the cartridge seats precisely in the four compatible models, eliminating the misalignment that can cause jams or sensor errors. The sealed design protects toner from humidity until installation, preserving shelf life. Buyers who need colour output or a higher-capacity black cartridge for other Canon devices will need a different product.

Questions about this item

Does the GPR-42 toner cartridge produce noticeable fan noise or heat during long print runs?

The cartridge itself has no moving parts or fans; any noise or heat comes from the imageRUNNER ADVANCE printer engine, not from the toner supply.

Which specific printer models must I already own for this 4791B003AA cartridge to work?

It is designed for the Canon imageRUNNER ADVANCE 4045, 4051, 4245 and 4251; it will not fit other Canon or third-party devices.

Will the 34200-page yield at 5% coverage still be accurate if I keep using an older imageRUNNER ADVANCE 4045?

Yes, the rated yield is based on the cartridge formulation and 5% coverage standard, so it applies equally to all four compatible models regardless of age.
