To identify the correct RAP to use, go to the 05BDADH Document Present Sensor Failure Entry RAP.• Remove all documents from the DADH.• Check the actuator for the document present sensor, PL 5.15 Item 12.• The DADH document present sensor can fail to detect the last document in a documentset if static electricity is on the input tray. If necessary, clean the input tray with the anti-static fluid, refer to ADJ 5.4.ProcedureWARNINGSwitch off the electricity to the machine, GP 14. Disconnect the power cord from thecustomer supply while performing tasks that do not need electricity. Electricity cancause death or injury. Moving parts can cause injury.Enter dC330 code 05-310 to check the DADH document present sensor, Q05-310, Figure 1.The display changes.Y NGo to Flag 1. Check Q05-310.References:• GP 11 How to Check a Sensor.• P/J184, DADH PWB.• 01D +3.3V Distribution RAP.• 01B 0V Distribution RAP, refer to the 3.3V return.Install new components as necessary:• DADH document present sensor, PL 5.15 Item 13.• DADH PWB, PL 5.10 Item 5.Make sure that the area around the sensor is clean. If the problem continues, install new com-ponents as necessary:• DADH document present sensor, PL 5.15 Item 13.• DADH PWB, PL 5.10 Item 5.• DADH document present sensor actuator, PL 5.15 Item 12.Figure 1 Component locationFigure 2 Circuit diagramDADH document present sensorQ05-310
