4085-001 FRU Action 3 Paper Feed Pick Motor With the power on, check for the following readings: (J3) pin 3 to ground = 5 V dc (J3) pin 6 to ground = 35 V dc (J3) pin 7 to ground = 35 V dc (J3) pin 10 to ground = 5 V dc If voltage is incorrect, replace tray 2 card. If voltage is correct, disconnect (J3). Check between 6 and 7 on the connector for approximately 11.8 ohms. If reading is incorrect, replace the paper feed pick motor assembly. If reading is correct, check the continuity between each 6 and 7 to the motor case. If continuity exists, replace the paper feed pick motor assembly. Paper Feed Motor With the power on, check the voltage at (J1) paper feed motor connector. The voltage at each pin should read approximately 34 V dc. If voltage is correct check continuity. If continuity is incorrect, replace the paper feed motor. If symptom remains, go to step 4. Note: If a short exists in the paper feed motor, damage to the engine board drivers and power supply may occur. 4 Tray 2 Sensor Check See "Tray 2 Sensor Test" on page 3-27 . If test fails, replace the sensor. 5 RIP Card Cable Check the continuity of the RIP card cable. If incorrect, replace the cable. If correct, replace the RIP card. Power Supply Service Check Dead Machine Note: Remove paper from printer prior to performing the dead machine service check. Observe all necessary ESD precautions when removing and handling the RIP card, engine board, or any of the installed option cards or assemblies. FRU 1 AC Outlet Action Check the AC outlet for correct line voltage. If incorrect, inform the customer. Diagnostic Information 2-63
