The MX-M3550 uses a single toner cartridge, SHR MX-561NT (SHR MX561NT). SHR MX-561NT yields 40000 pages.
The SHR MX-561NT cartridge has an approximate yield of 40000 pages.
When the MX-M3550 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 SHR MX-561NT.
