TROUBLESHOOTING

2-8. Control Panel Displays the Error Message "SET EP CARTRIDGE"

Step
1 Has the EPX toner cartridge been set in position?
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) CRU sensor PCB, (2) MCU PCB, (3) CRU sensor assy
(4) EPX toner cartridge, (5) Harness assy HVPS
(6) LVPS assy
3 (Check CRU switch of CRU sensor PCB)
Is the CRU switch of the CRU sensor functioning normally?

2-9. Control Panel Displays the Error Message "LOAD ??? CASS." or "LOAD ??? LCAS."

Step
1 Has the cassette been set in place?
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) Size spring, (6) Harness assy out
(7) Harness assy 1tray, (8) Paper cassette, (9) MCU PCB
(10) LVPS assy
3 (Check paper cassette) *1 *2 *3
On the paper cassette, have the positions of the size springs (the
section which comes in contact with the paper cassette) changed,
so that the ON/OFF combinations of the four paper size switches
for the feeder PCB {feeder PCB aux} match the paper size?
• As the paper cassette is set in place, visually check the
clearance at the back of the machine.
4 (Check paper size switch data) *1 *2
Does the paper size switch data match the ON/OFF combina-
tions of the four paper size switches for the feeder PCB {feeder
PCB aux}?
• Change the positions of the size springs (the section which
comes in contact with the paper cassette) to check the
alignment.
*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 { }.
*2: For the correspondence between the paper sizes, the ON/OFF combinations of the paper size switches, and the paper
size switch data, please refer to Chapter 4, Section 5-2-4.
*3: The paper guides on the paper cassette should be lined up to match the paper being used.
