Step C h e c k p o i n t
1 Is connector disconnected?
2 Disconnect connector CN6
on the PWB-A board and
check coil resistance
between pin 7 and pin 8 on
the disconnected cable side
of the connector using a
multimeter.
Is the resistance
approximately 80 ohms?
If the coil is shorted, check
the solenoid drive circuit
using the procedure below:
1. Set the multimeter for
voltage.
2. Place the (--) terminal of
the multimeter on pin 7
of connector CN6 on the
PWB-A board.
3. Place the (+) terminal of
the multimeter on pin 5
(GND).
With power on, does the
multimeter detect any
current?
3 Is paper take-up sensor flag
position incorrect?
