Step
Check
Treatment
Yes
No
1
*Initial setting
Use of parts of non-EPSON specifications, improper mounting, damage, distortion, dirt,
adherence of foreign matter?
*Main parts to check
FUSER ASSY, MAIN HARNESS ASSY, MCU PWB
Replace and remount
the concerned part(s).
Go to step 2.
2
*Engine and controller division check
Can a test print (single sheet / consecutive printing, about 10 sheets each) be performed
normally with the engine alone?
Printer controller check
(If an error still occurs
after replacing, go to
step 3.)
Go to step 3.
3
*FUSER ASSY mounting check
Is the FUSER ASSY pushed in securely?
Go to step 4
Replace the faulty
part(s).
4
*FUSER ASSY mounting detection check
Is the detection of the FUSER ASSY mounting functioning properly?
Replace the MCU PWB.
Go to step 5.
5
*FUSER ASSY power supply check
Is the voltage 5VDC between P19-16PIN <=> P19-15PIN 5VDC ?
Go to step 6.
Go to FIP-2.1
6
* MAIN P/H FRAME mounting signal check
Is the voltage between P19-16PIN <=> P19-15PIN as follows?
When the FUSER ASSY is closed, the value is 0VDC.
When the FUSER ASSY is opened, the value is 5VDC.
Go to step 7.
Replace the MCU PWB.
7
*MAIN HARNESS ASSY continuity check
Is there a proper continuity between J019 <=> P71?
Replace the FUSER
ASSY.
Replace the MAIN
HARNESS ASSY.
