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 1 Figure 59. Override SW301 1 Remove the left side cover. (See “Left side cover” on page 18.) Disconnect the door swing arms. 2 Install the toner cartridge, which will press SW301. 3 Press 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 to observe paper motion. See “Engine test” on page 79. 86 Chapter 3 - Troubleshooting Q1342-90910
