January 20072-175WorkCentre 7132 012-224 (A-Finisher)Status-indicator-rapsRevision012-224 (A-Finisher) Rear Tamper Home Sensor OFF FailBSD-ON:CH15.4• At the end of the operation of trying to turn Off the Rear Tamper Home Sensor that wasOn, the Rear Tamper Home Sensor was not detected being Off.• The Rear Tamper Home Sensor should have turned Off and then the Rear Tamper Motorstopped, but the Rear Tamper Home Sensor was On.Initial Actions• Check the Rear Tamper Home Sensor is properly installed and has no foreign object andthat the actuator is not broken.• Power Off/ON.ProcedureCheck the Rear Tamper for any foreign object, deformation and binding that prevents it frommoving. The Rear Tamper is free from defects and binding.Y NRepair the deformation and remove the foreign object(s) and the binding.Check the drive mechanism to the Rear Tamper for a deformed or broken part and not-seatedgears. The drive mechanism is in normal condition, not deformed or broken and with nonot-seated gears.Y NRepair the Rear Tamper drive mechanism.Enter Component Control [012-221]. Move the Rear Tamper by hand to block and unblock theRear Tamper Home Sensor. The display of changes.Y NCheck the connections of P/J8700 and P/J8726. P/J8700 and P/J8726 are securelyconnected.Y NConnect P/J8700 and P/J8726 securely.Check for an open or short circuit between J8700 and J8726. The wires betweenJ8700 and J8726 are OK.Y NRepair the open wire or short circuit.Measure the voltage between Finisher PWB J8700-12 (+) and GND (-). The voltage isapprox. +5VDC.Y NGo to Wirenet 7.2.36 A-Finisher +5VDC and check the +5VDC circuit.Measure the voltage between Finisher PWB J8700-11 (+) and GND (-). Move the RearTamper by hand to block and unblock the Rear Tamper Home Sensor. The voltagechanges.Y NReplace the Rear Tamper Home Sensor (PL 22.9).Check the wires and connectors for an intermittent open or short circuit. If the problemcontinues, replace the Finisher PWB (PL 22.7).Enter [012-026] and [012-029] alternately. The Rear Tamper Motor rotates.Y NCheck the connections of P/J8710, P/J8737A and P/J8737B. P/J8710, P/J8737A andP/J8737B are securely connected.Y NConnect P/J8710, P/J8737A and P/J8737B securely.Check for an open wire or short circuit between J8710, P/J8737A and J8737B. The wirebetween J8710, P/J8737A and J8737B are OK.Y NRepair the open or short circuit.Measure the voltage between Finisher PWB J8710-1 (+) and GND (-), and betweenJ8710-3 (+) and GND (-). The voltage is approx. +24VDC.Y NGo to Wirenet 7.2.38 A-Finisher +24VDC and check the +24VDC circuit. If the prob-lem continues, replace the Finisher PWB (PL 22.7).Repair the Rear Tamper Motor (PL 22.10). If the problem continues, replace the FinisherPWB (PL 22.7).Check the wires and connectors for an intermittent open or short circuit. If the problem contin-ues, replace the Finisher PWB (PL 22.7).AABB
