Chapter 16
16.3.10.6 E004-0003 Error code Or message 'Remove the paper from the finisher
trays.': after implementing countermeasure against malfunction of fixing feeder
unit open/closed sensor
Symptom
E004-0003 or message 'Remove the paper from the finisher trays.': after implementing countermeasure against
malfunction of fixing feeder unit open/closed sensor Error Code
Description
This symptom occurs after attaching a sheet of mylar to the sensor flag for the fixing feeder unit open/closed
sensor as a countermeasure against malfunction
Cause
1. While attaching a sheet of mylar to the sensor flag, the delivery vertical path cover open/closed sensor comes
off and short-circuited due to a contact with the sheet metal. Finally, the DC fuse PCB (FG3-2337) is broken.
2. Since the face-down delivery sensor 1 comes off, a message 'Remove the paper from the finisher trays.' is
displayed.
Field Remedy
1. Replace the DC fuse PCB with a new one.
2. Reinstall the face-down delivery sensor 1.
Note: When implementing the countermeasure, be careful not to detach the face-down delivery sensor 1 and the
delivery vertical path cover open/closed sensor.
