Table 5-6. Clear Paper Jam (2)
Cause Step Checkpoint Finding Solution
The paper take-up
solenoid coils may be
open or shorted.
1
Disconnect CN203 on the
C180 MAIN board, and check
the coil resistance between
pins 5 and 6 on the
disconnected cable side of the
connector using a multimeter.
Is the resistance
approximately 80 ohms?
No
Replace the paper
take-up solenoid.
If the coil is shorted, check the
solenoid drive circuit using the
procedure below:
1. Set the multimeter to
voltage.
2. Place the (–) terminal of
the multimeter on pin 5
of connector CN207 on
the C180 MAIN board.
3. Place the (+) terminal of
the multimeter on pin 6
(GND).
With power on, does the
multimeter detect any current?
Yes
Replace the paper
take-up solenoid
and the C180 MAIN
board.
The main motor coils
may be open or shorted.
2
Disconnect CN206 on the
C180 MAIN board, and check
the coil resistance between
pins 1 and 2 and between pins
3 and 4 (2 points total) on the
disconnected cable side of the
connector using a multimeter.
Pin 1 — Pin 2
Pin 3 — Pin 4
Are the resistances of all four
points approximately 10 ohms?
No
Replace the main
motor.
3
If any coil is shorted, check the
main motor drive circuit using
the following procedure:
1. Set the multimeter to
voltage.
2. Place the (–) terminal of
the multimeter on pins
1, 2, 3, or 6 of CN206
on the C180 MAIN
board.
3. Place the (+) terminal on
pin 2 of CN207 on the
C180 MAIN board
(GND).
With power on, does the
multimeter detect current?
Yes
Replace the C180
MAIN board.
