Toner Cartridges, Maintenance Kits and Parts

One Item
The 5042 uses a single toner cartridge, XER 6R112. XER 6R112 yields 12500 pages.
The XER 6R112 cartridge has an approximate yield of 12500 pages.
A "Supply Problem" message on the 5042 usually points to a chip-communication hiccup rather than an empty cartridge. Power-cycle the printer (off for 30 seconds, then on), reseat the cartridge until it clicks into place, and gently clean the gold chip contacts with a dry cloth. If the message returns, a replacement XER 6R112 will clear it.
