Check item Check work
Action to be taken
at NG
(6-1-1) Check condition of the running path.
Paper running path
of the front unit
Check if paper is jammed or not in the paper
running path.
Remove the
jammed paper.
(6-1-2) Check condition of the mechanical parts
Check the sensor
lever of the WR
sensor.
Check if shape and movement of the sensor
levers have any abnormality or not.
Replace the
sensor lever with
the good sensor
lever.
(6-1-3) Check condition of electrical parts
Check the detection
condition of the
sensor signal.
Confirm that the sensor signals are normally
detected by using the SWITCH SCAN function of
the self-diagnostic mode.
Replace either
the PU board
or the front
sensor board
(RSF PCB)
or connection
cable.
Check the sensor
lever of the WR
sensor.
Check for the following signals at the FSNS
connector
of the PU board.
Pin-2: WR sensor
Confirm that the above signal levels change
when the sensor lever is operated.
Replace the
front sensor
board (RSF
PCB)
Check the power
voltages supplied
to the front sensor
board (RSF PCB)
Check the 5V power at the CN connector
of
the front sensor board (RSF PCB).
Pin-1: 5V power supply
Pin-5: 0VL
Replace the
connection
cable.
(6-2) Jam occurs immediately after a paper is taken into printer.
Check item Check work
Action to be taken
at NG
(6-2-1) Check condition of the paper running path
Paper running path
on the belt.
Remove the ID unit and check if paper is jammed
or not in the paper running path.
Remove the
jammed paper.
(6-2-2) Check condition of the mechanical parts
Check the sensor
lever of the WR
sensor.
Check if shape and movement of the sensor
levers have any abnormality or not.
Replace the
sensor lever with
the good sensor
lever.
(6-2-3) Motor operation check
Paper feed motor
driver, belt motor
driver and ID motor
Confirm that the paper feed motor, belt motor
and ID motor work normally by using the Motor
& Clutch Test of the self-diagnostic mode.
Check if any load exists or not.
Replace the PU
board, or replace
the defective
motor among
paper feed
motor, belt motor
and ID motor, or
replace the ID
unit or belt unit.
If any attempt
of using new ID
unit or new belt
unit as a trial
is going to be
made, be sure to
use the System
