The Eject Clamp mechanism movessmoothly.Y NReplace the parts that are interfering with operation.Execute Component Control[012-251 Set Clamp Home Sensor]. Actuate the Set ClampHome Sensor with paper. The display changes.Y NCheck the connections of J8871 and P/J8988. J8871 and P/J8988 are connectedcorrectly.Y NConnect J8871 and P/J8988.Check the wire between J8871 and J8988 for an open circuit or a short circuit (BSD12.23). The wire between J8871 and J8988 is conducting without an open circuit ora short circuit.Y NRepair the open circuit or short circuit.Measure the voltage between the Finisher PWB P8988-12 (+) and GND (-) (BSD 12.23).The voltage is approx. +5VDC.Y NReplace the Finisher PWB (PL 23.16).Measure the voltage between the Finisher PWB P8988-11 (+) and GND (-) (BSD 12.23).Actuate the Eject Clamp Home Sensor with paper. The voltage changes.Y NReplace the Eject Clamp Home Sensor (PL 23.11).Replace the Finisher PWB (PL 23.16).Alternately execute Component Control[012-054 Eject Motor FWD LO] and Component Con-trol[012-055 Eject Motor FWD HI]. The Eject Motor (PL 22.9) starts up.Y NCheck the connections of P/J8878 and P/J8983. P/J8878 and P/J8983 are con-nected correctly.Y NConnect P/J8878 and P/J8983.Check the wire between J8878 and J8983 for an open circuit or a short circuit (BSD12.22). The wire between J8878 and J8983 is conducting without an open circuit ora short circuit.Y NRepair the open circuit or short circuit.Measure the resistance of the Eject Motor (PL 22.9) between each point of J8878-1/3/4/6(BSD 12.22). The resistance is approx. 2Ohm.Y NReplace the Eject Motor (PL 22.9).Measure the voltage between the Finisher PWB (PL 23.16) P8983-5/6/7/8 (+) and GND (-) (BSD 12.22). The voltage is approx. +24VDC.Y NReplace the Finisher PWB (PL 23.16).Replace the Eject Motor (PL 22.9). If the problem persists, replace the Finisher PWB (PL23.16).Execute Component Control[012-050 Set Clamp Clutch ON]. The Set Clamp Clutch (PL23.11) starts operating.Y NCheck the connections of P/J8877 and P/J8983. P/J8877 and P/J8983 are con-nected correctly.Y NConnect P/J8877 and P/J8983.Check the wire between J8877 and J8983 for an open circuit or a short circuit (BSD12.23). The wire between J8877 and J8983 is conducting without an open circuit ora short circuit.Y NRepair the open circuit or short circuit.Measure the voltage between the Finisher PWB (PL 23.16) P8983-4 (+) and GND (-).The voltage is approx. +24VDC.Y NReplace the Set Clamp Clutch (PL 23.11). If the problem persists, replace the Fin-isher PWB (PL 23.16).Replace the Eject Motor (PL 22.9). If the problem persists, replace the Finisher PWB (PL23.16).Replace the Finisher PWB (PL 23.16).AABB
