February, 20082-318 WorkCentre 5225, 5230024-980 (A-Finisher)Launch VersionStatus Indicator Raps024-980 (A-Finisher) Stacker Tray Full StackBSD-ON:12.8One of the following:• At Power On, the Stack Height Sensor detected the height and the Full position.• During the operation of adjusting (lowering) the height of the Stacker Tray for small paperto be ejected, the Full position was detected.• During the operation of adjusting (lowering) the height of the Stacker Tray for large paperto be ejected, the Half position (Full-of-Large-Sheets position) was detected.• With the Half position (Full-of-Large-Sheets position) already detected, paper (largepaper) a stack of which is limited to the Half position was ejected.Initial Actions• Check that the Stack Height Sensor is properly installed, not broken and has no foreignobjects.• Check Stacker Stack Sensors 1 and 2 are properly installed and free from foreign objectsand that their actuators are not broken.• Power Off/On.ProcedureCheck for remaining paper and foreign objects on the Stacker Tray. The Stacker Tray is freeof paper and/or foreign objects.Y NRemove the remaining paper and/or foreign object(s).Check the drive mechanism to the Stacker Tray for a deformed or broken part and not-seatedgears. The drive mechanism is free of defects and the gears seat properly.Y NRepair the Stacker Tray mechanism.Enter COmponent Control [012-267]. Block and unblock the Stack Height Sensor with a pieceof paper. The display changes.Y NCheck the connections of P/J8708 and P/J8727. P/J8708 and P/J8727 are securelyconnected.Y NConnect P/J8708 and P/J8727 securely.Check for an open or short circuit between J8708 and J8727. The wires betweenJ8708 and J8727 are OK.Y NRepair the open or short circuit.Measure the voltage between J8708-3 (+) on the Finisher PWB and GND (-). The volt-age is approx. +5VDC.Y NGo to Wirenet A-Finisher +5VDC and check the +5VDC circuit.Measure the voltage between J8708-2 (+) on the Finisher PWB and GND (-). Block andunblock the Stack Height Sensor with a piece of paper. The voltage changes.Y NReplace the Stack Height 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).Run DC330[012-278].Enter [012-278]. Rotate the Stacker Stack Sensor 1 actuator by hand to block and unblock thesensor. The display changes.Y NCheck the connections of P/J8707 and P/J8722. P/J8707 and P/J8722 are securelyconnected.Y NConnect P/J8707 and P/J8722 securely.Check for an open or short circuit between J8707 and J8722. The wires betweenJ8707 and J8722 are OK.Y NRepair the open wire or short circuit.Measure the voltage between J8707-6 (+) on the Finisher PWB and GND (-). The volt-age is approx. +5VDC.Y NGo to Wirenet A-Finisher +5VDC and check the +5VDC circuit.Measure the voltage between J8707-5 (+) on the Finisher PWB and GND (-). Rotate theStacker Stack Sensor 1 actuator by hand to block and unblock the sensor. The voltagechanges.Y NReplace the Stacker Stack Sensor 1(PL 22.8).Check the wires and connectors for an intermittent open or short circuit. If the problemcontinues, replace the Finisher PWB (PL 22.7).Run DC330[012-279].Enter [012-279]. Rotate the Stacker Stack Sensor 2 actuator by hand to block and unblock thesensor. The display changes.Y NCheck the connections of P/J8707 and P/J8721. P/J8707 and P/J8721 are securelyconnected.Y NConnect P/J8707 and P/J8721 securely.Check for an open or short circuit between J8707 and J8721. The wires betweenJ8707 and J8721 are OK.Y NRepair the open or short circuit.Measure the voltage between J8707-3 (+) on the Finisher PWB and GND (-). The volt-age is approx. +5VDC.AABBC
