Re: c7903
Have you tried swapping the drum with another from the machine? If you swap it with the yellow drum and get a C7904 code its the Drum.
The drums are different for a TA250ci than the TA4/500 even though all the connections fit the EEPROMs are different. Are you definetly using the correct drum?Comment
