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 SW101 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 SW101
1 Remove the covers.
2 Press SW101 (callout 1).
Figure 78. Overriding SW101
3 While SW101 is engaged, perform an Engine Test to observe
paper motion. (See procedures earlier in this chapter.)
