Paper-path check
If media is not being picked up or is not moving through the paper path, you might want to
observe all of the paper-motion activities. Override the door interlock (SW301) and the laser/
scanner switch to observe the following actions:
● motor rotation
● solenoid action
● pickup-roller motion
● drive-roller, transfer-roller, fuser-roller and gear, and delivery-roller motion
To override SW301
Push a piece of heavy paper into the slot in the top cover (callout 1) to engage SW301.
To override the laser/scanner switch
Use a small flatblade screwdriver to override the laser/scanner switch (callout 2).
