Canon GPR-42 Black Toner Cartridge

The Canon CNMGPR42 is a GPR-42 black toner cartridge designed to keep imageRunner Advance printers operating reliably day after day. Built for the 4045, 4051, 4245, and 4251 models, it drops into the toner bay quickly and locks in place, so anyone in the office can handle a replacement without calling support.

With a yield of roughly 34,200 pages, the cartridge supports teams that move a steady stream of reports, invoices, contracts, or training manuals through the printer. Long runs finish without mid-job interruptions, and scheduled maintenance becomes easier to plan.

Because this is genuine Canon toner, every page shows text that looks deep black and graphics that appear clear, preserving the professional tone of client packets or internal presentations. Using the correct toner also helps protect the printer’s internal imaging components, reducing the risk of expensive downtime.
