Paper path check

If paper is not being picked up or is not moving through the paper

path, you might want to observe all of the paper motion activities.

Overriding the door interlock (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

To override SW301

Figure 100. Overriding SW301

Open the left side door and print cartridge door. Disengage the

two print cartridge door arms.

2 Install the print cartridge, which will press SW301.

3 Press down the laser/scanner interlock switch (callout 1) on the

laser/scanner.

4 While SW301 and the laser/scanner interlock are engaged,

perform an engine test or self-test to observe paper motion. (See

procedures elsewhere in this chapter.)
