The Transport Roll is ok.Y NReplace the Transport Roll.Check for foreign substances, distortion and paper powder in the paper transport path. Nodistortion, foreign substances, or paper powder are found in the paper transport path.Y NClear away the foreign substances and paper powder. Correct the distortion.Execute Component Control[012-190 H-Transport Entrance Sensor]. Actuate the H-TransportEntrance Sensor (PL 23.4) with paper. The display changes.Y NCheck the connections of J8861 and J8987. J8861 and J8987 are connected cor-rectly.Y NConnect J8861 and J8987.Check the wire between J8861 and J8987 for an open circuit or a short circuit (BSD12.14). The wire between J8861 and J8897 is conducting without an open circuit ora short circuit.Y NRepair the open circuit or short circuit.Measure the voltage between the Finisher PWB P8987-4 (+) and GND (-) (BSD 12.14).The voltage is approx. +5VDC.Y NReplace the Finisher PWB (PL 23.16).Measure the voltage between the Finisher PWB P8987-6 (+) and GND (-) (BSD 12.14).Actuate the H-Transport Entrance Sensor with paper. The voltage changes.Y NReplace the H-Transport Entrance Sensor (PL 23.4).Replace the Finisher PWB (PL 23.16).Power OFF. Open the H-Transport Top Cover. Cheat the H-Transport Interlock Sensor. PowerON. The H-Transport Belt rotates.Y NCheck the connections of P/J8862 and J8987. P/J8862 and J8987 are connectedcorrectly.Y NConnect P/J8862 and J8987.Check the wire between J8862 and J8987 for an open circuit or a short circuit (BSD12.14). The wire between J8862 and J8987 is conducting without an open circuit ora short circuit.Y NRepair the open circuit or short circuit.Measure the resistance of the H-Transport Motor between each point of J8862-1/2/5/6(BSD 12.14). The resistance is approx. 20Ohm.Y NReplace the H-Transport Motor (PL 23.4).Measure the voltage between the Finisher PWB J8987-21/22/23/24 (+) and GND (-),(BSD 12.14). The voltage is approx. +24VDC.Y NReplace the Finisher PWB (PL 23.16).Replace the H-Transport Motor (PL 23.4). If the problem persists, replace the FinisherPWB (PL 23.16).Replace the Finisher PWB (PL 23.16).AA
