Points to Note When Making Checks on the Printer Side
The machine's potential control mechanism is designed for both
copier image output and printer (PDL) image output, and its parameters
for potential control in service mode may be adjusted independently of
each other.
As such, when an image fault occurs, try to find out which side is
causing it, and generate the appropriate images (data) for adjustment of
related parameters.
