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
