1. Remove paper using pinset or some tool and
watch if separate claws have any trouble.
Clean around fuser.
2. Check locking works wells. Watch whether the
ribs of exit cover hace any burr or resisitive
edge. If they do, remove obstacles or replace.
1. When using the thick paper such as envelope,
card stock, label and OHP, one-sheet printing
is recommended
2. To use thin paper, face-down is recommended
1. Check whether the spring is expanded or not.
2. Check armature is well installed. It may be
unstable assemble.
1. Remove the Toner cartridge and open the
cover and press cover open switch lever and
measure the voltage with high voltage probe
and sending printing data. If the voltage is
normal, change the toner cartridge.
2. Check HV of in Engine B’d and change it.
1. Re-insert the film neatly into the front. When
inserting it, the Plate-knockup needs to be
aligned to the front.
2. Turn the power off and on. Open and close the
Top cover to return to the original state.
Fit the paper width using the Guide adjust.
Check where Jam 2 happens
1. Paper is curled and cannot exit.
2. Paper is curled in the exit cover?.
1. Tried to print and stack pages which
are not allowed for specific paper
type?
2. Does the too thin paper, which
passed through the fuser, touch the
Cover Fornt?
1. Check the spring of solenoid
2. Check the armature
assembly/cushion
3. Electrical check
1. Check the terminal output voltage
2. Check HVPS
1. Does the black film in MPF prevent
the paper loading?
2. Does the Plate-knockup prevent the
paper loading?
Is the Guide adjust set to the paper
width?
