January 20072-326 WorkCentre 7132024-916RevisionStatus-indicator-raps024-916 Mix Full Stack RAPBSD-ON:12.8The output paper stacked on the Finisher Stacker Tray reaches capacity (for the same papersize only).Initial Actions• Power Off/OnProcedureCheck the tray raise/lower mechanism for foreign substances and distortion. No distortion orforeign substances are found in the tray raise/lower mechanism.Y NClear away the foreign substances. Correct the distortion.Execute Component Control [012-267 Stack Height Sensor]. Actuate the Stack Height Sensorwith paper. The display changes.Y NCheck the connections of P/J8815, P/J8825 and P/J8850. P/J8815, P/J8825 and P/J8850 are connected correctly.Y NConnect P/J8815, P/J8825 and P/J8850.Check the wire between J8815 and J8850 for an open circuit or a short circuit (BSD 12.8Flag 1/Flag 2). The wire between J8815 and J8850 is conducting without an opencircuit or a short circuit.Y NRepair the open circuit or short circuit.Measure the voltage between the Finisher PWB P8850B-6 (+) and GND (-) (BSD 12.8Flag 2). The voltage is approx. +5VDC.Y NReplace the Finisher PWB (PL 17.12).Measure the voltage between the Finisher PWB P8850B-5 (+) and GND (-) (BSD 12.8Flag 2).Actuate the Stack Height Sensor with paper. The voltage changes.Y NReplace the Stack Height Sensor (PL 17.5).Replace the Finisher PWB (PL 17.12).Alternately execute Component Control [012-060 Stacker Motor up ON] and Component Con-trol [012-061 Stacker Motor down ON]. The Stacker Motor starts up.Y NCheck the connections of P/J8847 and P/J8827. P/J8847 and P/J8827 are con-nected correctly.Y NConnect P/J8847 and P/J8827.Check the wire between J8847 and P8827 for an open circuit or a short circuit (BSD 12.8Flag 5). The wire between J8847 and P8827 is conducting without an open circuit ora short circuit.Y NRepair the open circuit or short circuit.Replace the Stacker Motor (PL 17.10) If the problem persists, replace the Finisher PWB(PL 17.12).Replace the Finisher PWB (PL 17.12) If the problem persists, replace the MCU PWB (PL 11.1).AABB
