2-4 Phaser 3635MFP01-700, 01ADraft 4Status Indicator RAPs01-700 Stapler Door Open RAP01-700 The machine has detected that the stapler door is open. When the stapler door is openthere is no +24V to the stapler.ProcedureWARNINGSwitch off the electricity to the machine. Disconnect the power cord from the customersupply while performing tasks that do not need electricity. Electricity can cause death orinjury. Moving parts can cause injury.Refer to Wiring Diagram 9. Perform the following:1. Switch off the machine, then switch on the machine.2. Open the stapler door, PL 28.10 Item 9.3. Check that the interlock switch actuator on the stapler door is not missing or damaged. Ifnecessary, install a new stapler door, PL 28.10 Item 9.4. Check that the stapler door assembly closes correctly.5. Check the stapler door interlock switch. If necessary, install a new stapler door interlockswitch, PL 11.10 Item 2.NOTE: There is no component control code for the stapler door interlock switch.6. Check the wiring between the stapler door interlock switch and CN3 on the ConnectionPWB.7. If necessary, install a new connection PWB, PL 3.10 Item 17.01A Power Failure RAPUse this RAP to identify the cause of a power supply failure.ProcedureWARNINGSwitch off the electricity to the machine. Disconnect the power cord from the customersupply while performing tasks that do not need electricity. Electricity can cause death orinjury. Moving parts can cause injury.WARNINGTake care when measuring AC mains (line) voltage. Electricity can cause death or injury.WARNINGDo not repair or install a new fuse F01 on the SMPS. Repairing or installing a new fusecan cause overheating and a risk of fire.NOTE: Throughout this procedure, where further steps require the reconnection of a compo-nent, ensure they are reconnected before performing the next step.Refer to Wiring Diagram 1, Wiring Diagram 2, Wiring Diagram 3, Wiring Diagram 4, Wiring Dia-gram 5, Wiring Diagram 6, Wiring Diagram 7, Wiring Diagram 8, Wiring Diagram 9, Wiring Dia-gram 10 and Wiring Diagram 11. Perform the following:1. Ensure the supply voltage is correct. If possible, connect the machine to a known goodpower supply. If the original power supply is faulty, inform the customer.2. Disconnect the power cord from the power outlet and the machine. Check the continuityof the power cord. If necessary, install a new power cord.3. Disconnect CON1 on the SMPS. Check for AC supply voltage between pins 1 and 2 onthe connector. If necessary, install a new SMPS assembly, PL 1.12 Item 8.4. Check the fuse F01 on the SMPS. If necessary, install a new SMPS assembly, PL 1.12Item 8.NOTE: Fuse F01 is not spared.5. Remove the fuser, PL 10.10 Item 1. Check for continuity across the fuser heat lamp.Install new components as necessary, PL 10.12 and PL 10.15.NOTE: A cold fuser heat roll has a resistance of approximately 9 ohms (220V/240V) or1.6 ohms (110V).6. Switch off the power to the machine. Disconnect all connectors on the Connection PWBexcept CN5 and CN6.7. Switch on the power to the machine. If the machine switches on, perform step 8. If themachine fails to switch on, go to step 9.8. Sequentially reconnect each connector onto the Connection PWB. If the faulty circuit isidentified, repair the wiring or install components as necessary. If the machine still fails toswitch on, install a new connection PWB, PL 3.10 Item 17.9. Reconnect all connectors onto the Connection PWB. Disconnect all connectors from theMain PWB except CN26 and CN31.10. Switch on the power to the machine. If the machine switches on, perform step 11. If themachine fails to switch on, go to step 12.
