Fuser solenoid adjustment

Perform the fuser solenoid adjustment whenever you replace the fuser solenoid. Adjust the fuser solenoid while
installed in the printer. Adjust the screw on the eccentric mounted on the solenoid housing to provide an air gap
between the rear of the solenoid stator and the solenoid armature. The solenoid air gap for all models is 4.5 mm
± 0.1 mm.

Gap adjustment

The gap adjustment allows you to increase the minimum gap between sheets of paper as they are fed through
the printer. This adjustment reduces the printer overall performance, such as pages per minute, but can help in
reducing the amount of curl of some printed media, thus improving media stacking in the output bin.
