hi.
i've got a sharp mxm850 stating "install developer cartridge blk".
I have lots of these machines in the field and have never seen this message before. it has been displaying this message on and off for the past few months. each time the problem would be cleared by switching off, taking the dev unit out, putting back in and turning on. the fault would clear for a month , then reappear. only this time the message will not clear. ive cleared the developer counter, and even tried changing the dev. all looks ok with the connector on back of machine and dev unit itself. no damage to pins and no scraps of paper caught.
Has anybody ever seen this message on one of these machines before?
thanks in advance
