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 PS204 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 PS204
1 Remove the Printer Covers (Figures 6-2, 6-3, and 6-4).
2 Press the Door Open flag down (Figure 7-7, callout 1) and lift the EP Cartridge flag
(Figure 7-7, callout 2). These flags are located on top of the printer chassis to the
left of the Laser/Scanner assembly.
Overriding PS204
3 While holding the flags up, perform either an Engine Test or a Self Test to observe
paper motion. (See procedures earlier in this chapter.)
