[Major Occurrence Timing]
• Paper loading timing
[Major Troubleshooting]
1 Put papers in cassette and push
"Start" button.
2 If a paper stops before reaching
PE Sensor, remove it and
check the paper condition.
3 A) If no damage in the above 2),
set edge guide correctly after
putting papers in cassette and
retry.
B) If damage in the above 2),
check foreign materials /
parts come-off / parts
transformation in paper
path.
4 If not resolved by 3-A) & 3-B),
check foreign material / Part
come-off / surface condition of
LD Roller / PE Sensor Lever /
Main Board / PF Motor.
*1: If the printer can turn on but turns off right away, the protection circuit may cut off
the power due to an error such as a circuit failure.
*2: Only for manual duplex print
*3: Only for L200/L201.
*4: In case of "Not Trouble Found", check fatal error code.
