The Aficio MP C7501SP uses RIC 841357 (RIC C7501K), RIC 841358 (RIC C7501C), RIC 841359 (RIC C7501M), RIC 841360 (RIC C7501Y) toner cartridges.
When the Aficio MP C7501SP reports "Supply Problem", it usually just can't communicate with one cartridge's chip. Give the printer a full power-cycle, take out and firmly reinsert the flagged cartridge, and lightly buff its metal contacts with a dry, lint-free cloth. If the message stays, install a new cartridge in the reported colour.
