    Re: Yellow print on RICOH MPC 6503

    Hello, I just called Ricoh tehnician support, and He say me that the problem may come from humidity and temperature sensor : The toner density use infos of the humidity and temperature sensor in order to calibrate and make process control.
    Maybe the copier is too close of the wall...
    He say me too that the electric card is not at fault because there will be always the problem... and not alternatively...

    A few days ago on an MP C5000 the yellow unit gave a problem, with a yellow background but erasing the location of the ID sensor, I did what the guy described and nothing, then I cleaned all the contacts and it allowed me to take readings. and full image quality.

    Re: Yellow print on RICOH MPC 6503

    Hey mate did you change the whole developer unit or just the yellow dev? Has the issue come back? I have the same issue on the same machine but i am getting yellow potential sensor errors 381-04. I have a sensor dev and dev unit on order.
