4061-xx0 Ready-Bin x Full displays and paper feeds into bin x FRU 1 Bin x sensor Bin x sensor control board Action Check the sensor flag for binds. Make sure the sensor flag is not in an up position. If the sensor flag is operating correctly, replace the bin x sensor. If this does not fix the problem, replace the control board. 271.xx Paper Jam - Check Bin 1 displays-paper does not feed into the bin selected FRU 1 Deflector Deflector spring Deflector cover Deflector cover spring Shaft assemblies 2 Bin x solenoid assembly Control board 3 Mechanical linkage Motor assembly Action Check all the bin parts for missing or loose springs, binds in the deflector or deflector cover, broken or binding shaft assemblies, or broken gear teeth. If incorrect, repair as necessary. Check the solenoid for any binds. Make sure the solenoid is contacting the latch correctly. If incorrect, repair as necessary. If the solenoid appears to be operating mechanically, check the resistance of the solenoid. It measures between 30 and 50 ohms. If incorrect, replace the failing solenoid assembly. If correct, replace the control board. If the DC motor is functioning properly, check the gears, clutch, and other linkage parts for correct operation and wear, broken gear teeth, or damaged parts. If incorrect, replace the mechanical linkage assembly/DC motor assembly. 990.xx Service Error displays FRU 1 Mechanical linkage DC motor assembly 2 Control board Action Check the DC motor cable connector to be sure it is correctly installed at J2 on the control board. If correct, disconnect J2 from the control board and check the resistance of the motor on the cable connector. J2-1 to J2-2 measures between 115 and 135 ohms. Also check J2-1 and J2-4 to the motor case for shorts. If either the resistance is incorrect or a short is found, replace the mechanical linkage/DC motor assembly. Note: If the DC motor is shorted, it may also be necessary to replace the control board. Disconnect the motor cable J2 from the control board and check the voltages at J2 on the board. Warning: Use caution not to short adjacent pins on the connector as damage to the board could result. Pin Measured (motor idle) J2-1 +24 V dc J2-2 +24 V dc J2-5 +5 V dc J2-6 +5 V dc If any of the voltages are incorrect, replace the control board. If correct, replace the mechanical linkage/ DC motor assembly. 2-74 Service Manual
