Dear All,
I'm facing a problem on Ricoh Aficio MP-2554SP (Corona). Copy or print quality is very poor, First I've replaced OPC drum, then developer. But problem not solved then I also replaced full PCDU unit and Laser unit also but after a few days problem appears again. Another thing is that, if I give force toner supply by entering SP mode, machine runs well 2-3 hours but again copy/print quality became poor .
In this regard please help me to solve this issue.
