Step
1 Is the drive from the main motor
and the pre-registration motor 1/2
transmitted to each roller through
gears?
2 Set the meter range to 30 VDC, and
measure the voltage between J312-
A3 (+) and -A4 of the registration
path driver PCB. Does it change
from about 0 to about 24 V after
pickup?
3 Replace the registration path driver
PCB. Is the problem corrected?
