Paper curl
Paper curl is inherent to the laser printing processes, and occurs when paper is subjected to
heat. Paper curl tends to relax as the paper cools while resting on a flat surface. The
specification for maximum paper curl when the paper is lying flat before print is 0.2 inches (5
mm).
Paper path check
If paper is not being picked up or is not moving through the paper path, you may want to
observe all of the paper motion activities. Overriding SW301 allows you to observe:
•
Motor rotation
•
Solenoid action
•
Kick plate motion
•
Paper pickup roller motion
•
Drive roller, transfer roller, fuser roller and gear, and delivery roller motion
