Good afternoon. I have the problem that a Ricoh C305 does not recognize the black toner canister, the equipment has already been cleaned and 3 different toner canisters have been placed to discard the damaged chip, the toner canisters are original and completely new. It only indicates on the screen that the black toner bottle is not properly positioned. I would greatly appreciate your contributions. Best regards.

I have the same problem and I already cleaned the end of toner sensor

Hi Juan CV, any possibility of sharing this equipment manual

Hi, I have the same problem, the black has original cartridges if it detects it but the color ones say "independent supplier" and does not indicate any level of toner, but it works, this arose after disassembling the machine to change the pinions of the motor driver of the fuser, and above the counters of the machine of both copies and service were reset, I am about to update the firware, haver what happens. and I don't think it's a problem with the sensors or the tuffs or the boat.
