Compatible Black Toner 2-Pack

This SuppliesMax aftermarket cartridge set replaces the Gestetner Corp 841284_2PK and fits the MP-C4000, MP-C4000G, MP-C4000MFP, MP-C4000SPF, MP-C5000, MP-C5000G, MP-C5000MFP and MP-C5000SPF series. Each pack contains two black cartridges rated for 23000 pages at 5% coverage, suited for offices that run high-volume monochrome jobs on these machines.

Reliable Output on Supported 110V Printers

Built with new and recycled components in ISO 9001 and ISO 14001 certified facilities, the cartridges are designed for 110V devices sold in the U.S. and weigh 510 grams each. They install without tools and deliver crisp black text with consistent density across the rated yield, keeping maintenance intervals predictable for daily business use.

Upgrade From Single OEM Cartridges

Moving from a single OEM unit to this 2-pack cuts the cost per page and halves the frequency of swap-outs for the listed Gestetner models. The jump makes sense when monthly volumes approach the 23000-page rating; buyers who need colour toner or MICR formulation will not be served by this black-only kit.

Questions about this item

How do I install the SuppliesMax 841284_2PK black toner cartridge in my Gestetner MP-C5000, and what step is commonly missed?

Open the front cover, pull out the used black cartridge, remove all protective seals from the new 510-gram cartridge, and shake it gently five times to distribute toner evenly — skipping the shake causes streaky first prints.

What maintenance or replacement will the SuppliesMax 841284_2PK pack require after the 23000-page yield is reached?

Once each cartridge reaches its 23000-page rating at .05 coverage, replace the empty black cartridge with a new one; no drum or developer unit is included, so those stay in the printer unless a separate alert appears.

What limit appears first during continuous high-volume printing with the SuppliesMax 841284_2PK on a 110V Gestetner MP-C4000?

The 23000-page yield at .05 coverage is the first hard limit — after that volume the toner is exhausted and the cartridge must be swapped, even if the printer shows no other warnings.
