Error with my bizhub 420 again
Error code C-2701 related with charging abnormality. Based on Service manual, estimated abnormal part is Charging Corona, HV and PRCB. I replaced the Charging corona, then checking the HV and PRCB is fine Then I do trouble reset. No C-2701 appear. But, next day the evil code is appear again.
I don't know what's going on with my bizhub 420.
Any solution? Thank you for sharing solution.
