4060-xxx Remove Paper - Output Bin x is displayed, POST incomplete, unable to clear the message. FRU 1 Dual output bin sensor flag Action Check the flag for correct operation, binding, broken parts, or interference from the sensor cable, If incorrect, repair as necessary. 271 Paper Jam - Check Bin x, POST incomplete FRU 1 Pass thru sensor and flag assembly Control board Action Check the sensor flag for proper operation. If correct, check to make sure the pass thru sensor cable is correctly connected to J3 on the control board. Disconnect the pass thru sensor cable from J3 on the control board and check the voltage at J3-3. The voltage measures approximately +5 V dc. If incorrect, replace the control board. If correct, check the voltage at J3-2. The voltage measures approximately 0 V dc. If incorrect, replace the sensor assembly. If this does not fix the problem, replace the control board. 271 Paper jam - Check Bin x, POST complete, first sheet of paper feeds into output bin x. Note: Before performing the following checks, run the Output Bin X Sensor Test and check for the failing sensor. Sensor Test: NF = Near Full (Upper part of sensor assembly) F = Full (Lower part of sensor assembly) P = Pass Thru Sensor 990 Service - Bin x FRU 1 D.C. motor mechanical linkage assembly Action Make sure the DC motor cable connector is correctly installed at J4 on the output expander option board. If correct, disconnect J4 from the option board and check the resistance of the motor on the cable connector: J4-1 to J4-2 (measures between 115 and 135 ohms.) Also check J4-1 and J4-2 to the motor case for shorts. If either the resistance is incorrect or a short is found, replace the motor/ mechanical linkage assembly. Note: If the DC motor is shorted, it may also be necessary to replace the control board. 2-74 Service Manual
