12-100 H Transport Entrance Sensor On
The H Transport Entrance Sensor does not detect paper within the specific time after the Reg-
istration Clutch (in IOT) actuated.
Procedure
Enter dC330 [012-001] and press Start. The Finisher Drive Motor energizes.
YN
Press Stop. Repair the drives as required (PL 17.7) for mechanical problems. If the
drives are mechanically good, check the circuit of the Finisher Drive Motor (Figure 4). +5
VDC is measured between J846-3 on the Finisher PWB and Finisher PWB Chassis
(-).
YN
Check the wire between J846-3 on the Finisher PWB and J879-1 on the Finisher
Drive Motor PWB.
If the wire is good, replace the Finisher Drive Motor (PL 17.7).
Press Start and check the voltage between J846-3 on the Finisher PWB and Finisher
PWB Chassis (-). Less than +1 VDC is measured.
YN
Replace the Finisher PWB (PL 17.3).
Check the voltage between J846-7 and -5 on the Finisher PWB and Finisher PWB Chas-
sis (-). +24 VDC is measured.
YN
Replace the Finisher PWB (PL 17.3).
Check the resistance between j846-11 and -9 on the Finisher PWB and Finisher PWB
Chassis (-). Less than 10 ohms is measured.
YN
Replace the Finisher PWB (PL 17.3).
Replace the Finisher Drive Motor (PL 17.3).
Enter dC330 [012-103] and press Start. Actuate and deactuate the H Transport Entrance Sen-
sor. The display changes.
YN
Repair the sensor as required (PL 17.4) for mechanical problems. If the sensor is
mechanically good, check the circuit of the H Transport Entrance Sensor (Figure 2).
Enter dC330 [012-060 or 061] and press Start. The gate changes position.
YN
Repair the gate as required (PL 17.4) for mechanical problems. If the gate linkage is
mechanically good, check the circuit of the Gate In Solenoid (Figure 3).
Check the following:
ï Paper path failure for burr and foreign substance.
ï H-Transport Belt for contamination, wear and a drive failure
ï Sensor Actuator for breakage
