Status Indicator RAPs Initial issue
12-262 Eject Clamp Home Sensor Off
The Eject Clamp Home Sensor does not turn off within 200ms after the Eject Clamp DOWN
has started.
Procedure
Remove the Rear Cover ( PL 17.5 ) and the Eject Clamp Home Sensor bracket ( PL 17.8 ) (leave
sensor connected). Enter dC330 [012-210] and press Start . Actuate the Eject Clamp Home
Sensor ( PL 17.8 ) ( Figure 1 ). The display changes.
Y N
Press Stop . Check the Eject Clamp Home Sensor components for mechanical problems.
If the components are good, check the circuit of the Eject Clamp Home Sensor ( Figure 2 ).
Refer to the OF 99-2 RAP for troubleshooting procedure
Press Stop . Restore mounting of the Eject Clamp Home Sensor. Enter dC330 [012-032] and
press Start . The Eject Clamp ( PL 17.6 ) moves down.
Y N
The Eject Motor (
Figure 3 ) energized.
Y N
Remove the Rear Cover ( PL 17.5 ). +24 VDC is measured between P/J881 - 2 and
5 on the Eject Motor and GND.
Y
N
+24 VDC is measured between
P/J846 - 6 and 12 on the Finisher PWB and
GND.
Y
N
Replace the Finisher PWB ( PL 17.13 ).
Check wiring between P/J846- 6 and 12 and P/J881- 2 and 5 for damage or
poor contact.
+24 VDC is measured between P/J881- 1, 3, 4 and 6 on the Eject Motor and
GND.
Y
N
Replace the Eject Motor ( PL 17.8 ).
Check the wires from P/J846 to P/J881 for an damage or poor contact. If the check
is OK, replace the Finisher PWB ( PL 17.13 ).
Check the Eject Motor and its associated gears, pulleys and belts ( PL 17.8 ) for damage,
contamination and misalignment.
Press Stop .
• Ensure that the connectors shown in the circuit diagrams ( Figure 2 , Figure 3 ) are securely
connected and that the wires are not damaged.
• Replace the Eject Clamp Home Sensor ( PL 17.8 ).
• If the problem persists, replace the Finisher PWB ( PL 17.13 ) ( Figure 4 ).
