Toner Cartridges, Maintenance Kits and Parts

One Item
The X534DN uses LEX C540A4KG toner cartridge. LEX C540A4KG yields 1000 pages.
The LEX C540A4KG cartridge has an approximate yield of 1000 pages.
A "Supply Problem" message on the X534DN 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 LEX C540A4KG will clear it.
