Black Genuine Toner Cartridge Standard Yield, 1,500 pages
The ML 1640 uses a single toner cartridge, SAS MLT-D108S (SAS 108 SU786A). SAS MLT-D108S yields 1500 pages.
The SAS MLT-D108S cartridge has an approximate yield of 1500 pages.
When the ML 1640 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 SAS MLT-D108S.
