The voltage changes.Y NReplace the Registration Sensor (PL 2.4).Replace the MCU PWB (PL 9.1).Replace the MCU PWB (PL 9.1).024-916 Mix Full Stack RAPThe output paper stacked on the Finisher Stacker Tray reaches capacity (for the same papersize only).Initial Actions• Refer to BSD 12.8.ProcedureCheck 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 (BSD12.8). The wire between J8815 and J8850 is conducting without an open circuit or ashort circuit.Y NRepair the open circuit or short circuit.Measure the voltage between the Finisher PWB P8850B-6 (+) and GND (-) (BSD 12.8).The voltage is approx. +5VDC.Y NReplace the Finisher PWB (PL 22.7).Measure the voltage between the Finisher PWB P8850B-5 (+) and GND (-) (BSD 12.8).Actuate the Stack Height Sensor with paper. The voltage changes.Y NReplace the Stack Height Sensor (PL 22.10).Replace the Finisher PWB (PL 22.7).Alternately execute Component Control[012-060 Stacker Motor up ON] and Component Con-trol[012-061 Stacker Motor down ON]. The Stacker Motor (PL 22.10) starts up.Y NCheck the connections of P/J8847 and P/J8827. P/J8847 and P/J8827 are connectedcorrectly.Y NConnect P/J8847 and P/J8827.Check the wire between J8847 and P8827 for an open circuit or a short circuit (BSD12.8). The wire between J8847 and P8827 is conducting without an open circuit or ashort circuit.AA
