February, 20082-106 WorkCentre 5225, 5230012-223 (A-Finisher)Launch VersionStatus Indicator Raps012-223 (A-Finisher) Front Tamper Home Sensor OFF FailBSD-ON:12.4• At the end of the operation to turn Off the Front Tamper Home Sensor that was On, theFront Tamper Home Sensor was not detected being Off.• The Front Tamper Home Sensor should have turned Off and then the Front Tamper Motorstopped, but the Front Tamper Home Sensor was On.Initial Actions• Check the Front Tamper Home Sensor is properly installed and has no foreign object andthat the actuator is not broken.• Power Off/ON.ProcedureCheck the Front Tamper for any foreign object, deformation and binding that prevents it frommoving. The Front Tamper free from defects and binding.Y NRepair the deformation and remove the foreign object(s) and the binding.Check the drive mechanism to the Front Tamper for a deformed or broken part and not-seatedgears. The drive mechanism is free from defects and the gears seat properly.Y NRepair the Front Tamper drive mechanism.Run DC330[012-220].Enter Component Control [012-220]. Move the Front Tamper by hand to block and unblock theFront Tamper Home Sensor. The display changes.Y NCheck the connections of P/J8700 and P/J8724. P/J8700 and P/J8724 are securelyconnected.Y NConnect P/J8700 and P/J8724 securely.Check for an open or short circuit between J8700 and J8724. The wires betweenJ8700 and J8724 are OK.Y NRepair the open or short circuit.Measure the voltage between Finisher PWB J8700-6 (+) and GND (-). The voltage isapprox. +5VDC.Y NGo to Wirenet A-Finisher +5VDC and check the +5VDC circuit.Measure the voltage between Finisher PWB J8700-5 (+) and GND (-). Move the FrontTamper by hand to block and unblock the Front Tamper Home Sensor. The voltagechanges.Y NReplace the Front Tamper Home Sensor (PL 22.10).Check the wires and connectors for an intermittent open or short circuit. If the problemcontinues, replace the Finisher PWB (PL 22.7).Enter [012-020] and [012-023] alternately. The Front Tamper Motor rotates.Y NCheck the connections of P/J8710, P/J8738A and P/J8738B. P/J8710, P/J8738A andP/J8738B are securely connected.Y NConnect P/J8710, P/J8738A and P/J8738B securely.Check for an open wire or short circuit between J8710, P/J8738A and J8738B. The wirebetween J8710, P/J8738A and J8738B are OK.Y NRepair the open wire or short circuit.Measure the voltage between Finisher PWB J8710-5 (+) and GND (-), and betweenJ8710-7 (+) and GND (-). Each voltage is approx. +24VDC.Y NGo to Wirenet A-Finisher +24VDC and check the +24VDC circuit. If the problem con-tinues, replace the Finisher PWB (PL 22.7).Replace the Front Tamper Motor (PL 22.10). If the problem continues, replace the Fin-isher PWB (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
