Toner Cartridges, Maintenance Kits and Parts

One Item
The 1040 uses a single toner cartridge, XER 6R112. XER 6R112 yields 12500 pages.
The XER 6R112 cartridge has an approximate yield of 12500 pages.
When the 1040 throws a "Supply Problem" error, the printer often simply can't read the cartridge chip. Give it a full power-cycle, take the cartridge out and put it back securely, and lightly buff the metal contacts with a dry, lint-free cloth. If it persists after all that, the cartridge is likely worn — install XER 6R112.
