Adjustment Procedures
CAUTION: Be sure to unplug the power cord whenever you are
working on the printer with one of the covers removed.
Print Registration Adjustment
Print the service diagnostic test page after you replace the engine
board. Check the position of the bottom left and right registration
lines. Adjust VR1 on the engine board to position both lines exactly
on the trailing edge of the page. A slight turn on VR1 produces
significant change in the registration line position. Turning the
adjustment clockwise increases the gap between the registration
lines and the trailing edge of the page and counter clockwise
decreases the gap.
