4.3.2.4 Malfunction
Error Status
Check
Solution
Cover open
1.
When close Side cover, check the
lever is pressed
2. Micro switch’s contact
3. CPU and related circuit
1.
Open Side cover and press the lever with pen.
If Controller detects cover close, there is some
mechanical trouble in Side cover and lever’s
assembly. If not so there is electrical problem.
Jam 0
Check where Jam 0 happens
1. Paper is not picked up
2. Paper is located in feed sensor
3.
Happened when inserting specific
papers such as envelope into the
MPF (Multipurpose Paper Feeder)?
4.
Happened when inserting specific
papers such as envelope into the
Manual Feeder?
5.
Is the Stacker Extender is folded
out?
6.
Does not the Guide Adjust distort the
papers
1.
Check whether solenoid is working or not by using
Engine test mode
2. Check feed sensor malfunction.
3. Re-try inserting a fewer papers.
• fan the papers and align
•
take out the loaded papers and insert them
reverse direction
4.
Take out the loaded papers and insert them
reverse direction
•
inserted papers as recommended for Manual
Feeding?
•
When loading, tap the papers until paper detect
sensor senses loading
5.
When using long papers, use the Stacker
Extender
6. Adjust Guide to fit the paper width
Jam 1
Paper is stopped in just after of fuser
unit.
1.
It is mostly resulted from double feeding.
Check paper is well stocked in feeder.
2.
Check feed actuator position and actuator’s
operating. There may be stiff movind or double
reflection. If not so, check the operation of feed
sensor by Engine test mode.
3.
Check exit lever operation. Remore jam and
check actuator moving by hand. If actuator is
too stiff, paper is wrapped around the heat roller.
Remove obstacles or replace.
Jam 2
Check where Jam 2 happens
1. Paper is curled and cannot exit.
2. Paper is curled in the exit cover?
1.
Remove paper using pinset or some tool and
watch if separate claws have any troble.
Clean around fuser.
2.
Check locking works wells. Watch whether the
