1. Check power is supplying
2. Check fuse F1 open
1. Thermostat open
2. AC wire open
3. Thermistor wire open
4. Main PBA
1. When close
Side cover, check the lever is
pressed
2. Micro switch’s contact
3. CPU and related circuit
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
Paper is stopped in just after of fuser unit.
1. If supplying power differs from machine’s
power rating, replace the machine.
2. Replace it.
1. Detach AC connector and measure the
resistane between pin 1 and 2. If it is
megohm, thermostat is open, Replace it.
2. Check bad connector contact or wire is cut.
3. Check thermistor wire and its connection.
4. Replace Main PBA
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 elec-
trical problem.
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
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 opera-
tion of feed sensor by Engine test mode.
3. Check exit lever operation. Remore jam
and check actuator moving by hand. If actu-
ator is too stiff, paper is wrapped around the
heat roller. Remove obstacles or replace.
