2-10. Control Panel Displays the Error Message “CASS: REFILL ???” or “LCAS: REFILL ???” or
“TRAY: REFILL ???”
Step Check
Measure
YES NO
1 Is there paper in the pertinent paper supply section?
2 Check parts with different specifications for problems with
usage, defective installation, breakage, deformation, and adhe-
sion of foreign matter.
•
Main parts to be checked:
(1) Feeder assy, (2) Optional feeder unit, (3) Feeder PCB
(4) Feeder PCB aux, (5) No paper actuator
(6) Paper cassette, (7) MBF sensor, (8) MBF actuator
(9) Harness assy out, (10) Harness assy 1tray
(11) Harness assy sensor, (12) MCU PCB
(13) LVPS assy, (14) Multi-purpose tray
3 Is paper being supplied from the front tray (multi-purpose
tray)?
4 (Check MBF actuator)
Does the MBF actuator move smoothly?
5 (Check bottom plate assy)
When there is no paper in the front tray (multi-purpose tray),
does the MBF actuator move into the notch provided for it in
the bottom plate assy, and when there is paper present, does it
rest on the paper?
6 (Check MBF sensor)
Is the MBF sensor functioning normally?
7 (Check paper cassette)
When the paper cassette is set in place, is the paper in the paper
cassette lifted upwards normally?
•
Check visually from the rear side of the machine.
8 (Check no paper actuator) *1
Does the no paper actuator of the feeder PCB {feeder PCB aux}
move smoothly?
9 (Check no paper sensor)
Is the no paper sensor of the feeder PCB {feeder PCB aux}
functioning normally?
*1: This is noted for both Tray 1 (upper cassette feeder) and Tray 2 (lower cassette feeder). To distinguish Tray 1 from
Tray 2, items concerning Tray 2 are enclosed in brackets { }.
