| ricoh af550 light, even blank image
Hallo,
Just after power-on, my Ricoh aficio 550 copier copies normal, after serveral minutes the image becomes lighter and lighter and later its totaly blank. By off and immidiate on, sc 101 appears. By off and later on, no cs appears.
I think my SBICU or SBU board is defective, can anyone confirm that or is it more simple |
