Kyocera Mita ECOSYS MA4000WIFX Supplies

The KYO TK1272 cartridge has an approximate yield of 10000 pages.

A "Supply Problem" message on the ECOSYS MA4000WIFX 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 KYO TK1272 will clear it.
