4060-xxx High-capacity feeder input tray service check Note: Voltage measurements in the high-capacity feeder input tray service checks must be made with the high-capacity feeder attached to the base printer to obtain accurate results. Service tip: Be sure the paper size switch is set to the correct paper size setting and the rear paper guides are in the correct locations for the size of paper installed in the high-capacity feeder tray. Service tip: Check the other paper sources to be sure they are operating correctly. The base printer indicates a dead machine condition when the high-capacity input tray is installed. FRU Action 1 AC line cord If the base printer works normally using the AC line cord from the AC AC jumper (HCIT to printer) wall outlet and does not work when using the AC jumper from the AC input and output HCIT, check the AC jumper cord. If defective, replace the cord. If not receptacles defective, check the AC input and output receptacles and wiring AC wiring harness harness in the HCIT. Repair or replace the receptacles or AC wiring harness as required. Note: Make sure the ground wire is installed correctly from the AC wiring harness to the frame of the HCIT and the nut and lock washer are tightened. The base printer does not recognize that the high-capacity input tray is installed. FRU 1 high-capacity feeder autoconnect mechanical check 2 Base printer or option mounted above 3 LVPS Option system board Action Check the high-capacity feeder input tray to make sure it is mounted correctly and is not pushed down into the frame assembly or damaged. Be sure the high-capacity feeder input tray autoconnect is properly connected to the high-capacity feeder tray option board assembly. Check the option or base printer autoconnect for signs of damage. Repair the high-capacity option autoconnect as necessary. Check the voltages at J11-2 and J11-4. The voltage measures +24 V dc, If the voltage is correct, replace the high-capacity system board assembly. If the voltage is incorrect, check the continuity of the AC input cable to the LVPS. If correct, replace the LVPS assembly. If incorrect, replace the AC cable to the input of the LVPS. 2-56 Service Manual
