012-260 Eject Clamp Home Sensor On Failure RAP (LX)

BSD-ON: BSD 12.22 - Office Finisher LX Eject Control (1 of 2)
After the Eject Clamp started ascending, the Eject Clamp Home Sensor did not turn On within
500ms.
Initial Actions
• Manually operate the Eject mechanism. Check for binding, a dirty sensor, or damage.
• Check the actuator for the Eject Clamp Home Sensor b for damage
Procedure
Execute Component Control [012-250], Eject Clamp Home Sensor. Block and unblock the
Eject Clamp Home Sensor The display changes.
Y N
Check the wire between J8870 pin 2 on the Eject Clamp Home Sensor and
8 on the Finisher PWB for an open or short circuit, or loose or damaged connectors. The
wire is OK.
Y N
Repair/replace as required.
Measure the voltage between P/J8988, pins 9 and 7 on the Finisher PWB. The voltage
is approx. +5VDC.
Y N
Replace the Finisher PWB (PL 23.16).
Measure the voltage between P/J8988
Eject Clamp Home Sensor. The voltage changes.
Y N
Replace the Eject Clamp Home Sensor
Replace the Finisher PWB (PL 23.16).
Alternately execute Component Control [012-052], Eject Clamp Up and [012-053], Eject Clamp
Down. The Eject Motor (PL 22.9) starts up.
Y N
Check the wires between P/J8878 pins 1~6 on the Eject Motor and
the Finisher PWB for an open or short circuit, or loose or damaged connectors

Y N
Repair/replace as required.
Measure the resistance of the Eject Motor between each pin of P/J8878-1/3/4/6. The
resistance is approx. 2Ohm.
Y N
Replace the Eject Motor (PL 23.11).
Replace the Finisher PWB (PL 23.16). If the problem remains, replace the Eject Motor
