Black Genuine Toner Cartridge Standard Yield, 1,500 pages
The SCX 3400F uses a single toner cartridge, SAS MLT-D101S (SAS 101 SU700A). SAS MLT-D101S yields 1500 pages.
The SAS MLT-D101S cartridge has an approximate yield of 1500 pages.
A "Supply Problem" message on the SCX 3400F 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 SAS MLT-D101S will clear it.
