Yes I have as per the manual, check and adj voltage for new drum , completed the 1-10 sequence, etc changed sensor board.
Some suggestions from KMBS.
Light/blank copies & 29-03 - Write unit may be bad.
SC29-03 after Toner concentration dipswitch settings changed - reset dipswitch.
this is what the service manual says.
f-29-03
control patches are not output while Dmax correction is in progress.
no output from the Dmax sensor.
remedy:
TSCB (toner control sensor board) thats the sensor that looks at the drum in the drum carraige.
or
PRCB (printer control board)
i would try the sensor (TSCB) first.
