To identify the correct RAP to use, go to the 05-330, 05-331 DADH Feed Sensor Failure Entry RAP.• Remove all documents from the DADH.• Make sure that the customer is not using damaged documents. If the DADH damages thedocuments, go to the 05F Damaged Documents RAP.• Figure 1. Check that the feed roll assembly is installed correctly, go to REP 5.14.• Figure 1. Make sure that the feed rolls are clean and rotate freely, refer to ADJ 5.4. If nec-essary, install a new feed roll assembly, PL 5.15 Item 1 or feed roll assembly cover, PL5.15 Item 21.• Figure 2. Check the operation of the feed yoke. Make sure that the feed yoke shaft isunder the clip. Make sure that the feed yoke spring is connected to the feed assembly andto the feed yoke.• While the DADH feed solenoid is not energized, make sure that the feed gates are lockedin the down position. Manually activate the DADH feed solenoid then make sure that thefeed gates move freely. Manually de-activate the DADH feed solenoid, PL 5.15 Item 5.NOTE: The feed solenoid remains activated (after being energized) until the last docu-ment has been fed. Then a reverse pulse de-actuates the armature to lift the nudger roll.• Check the location of the feed solenoid spring. Make sure the spring is correctly locatedon the solenoid armature.• Clean the DADH feed sensor and the area around the sensor, PL 5.15 Item 2.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.Open the DADH top cover. Remove the DADH rear cover, PL 5.10 Item 1. Hold the top coverinterlock switch closed. Enter dC330 code 05-330 to check the DADH feed sensor, Q05-330.Activate Q05-330. The display changes.Y NGo to Flag 1. Check Q05-330.References:• GP 11 How to Check a Sensor.• P/J184 DADH PWB.• 01D +3.3V Distribution RAP.• The 3.3V return in the 01B 0V Distribution RAP.Install new components as necessary:• DADH feed sensor, PL 5.15 Item 2.• DADH PWB, PL 5.10 Item 5.Enter dC330 code 05-020 to run the DADH feed motor, MOT05-020. MOT05-020 runs.Y NGo to the 05D DADH Motor Failure RAP.While MOT 05-020 runs, stack the code 05-025 to energize the DADH feed clutch, CL05-025.NOTE: The feed clutch disengages after 30 seconds. The feed motor stops after 3 minutes.CL05-025 energizes, the nudger rolls and the feed rolls rotate.Y NPerform the steps that follow:• Go to the 05E DADH Feed Clutch Failure RAP and check CL05-025.• ADJ 5.1, DADH Drive Belt Adjustment.Enter dC330 code 05-010 to energize the DADH feed solenoid, SOL05-010. The feed rollassembly lowers, then raises after 10 seconds.Y NGo to Flag 2. Check SOL05-010.References:• GP 12 How to Check a Solenoid or Clutch.• P/J183, DADH PWB and P/J201.• 01G +24V Distribution RAP.• The 24V return in the 01B 0V Distribution RAP.Install new components as necessary:• DADH feed solenoid, PL 5.15 Item 5.• DADH feed assembly, PL 5.15 Item 18.• DADH PWB, PL 5.10 Item 5.Perform the steps that follow:• Check that the DADH feed sensor, Q05-330 is installed correctly. If necessary, install anew feed roll assembly, PL 5.15 Item 1.• Ensure the feed motor drive belt and CVT motor drive belt are tensioned correctly, ADJ5.1.• When large documents are fed (A3 or 11x17 inch), check the following:– The CVT motor rotates freely, refer to 05D DADH Motor Failure RAP– The CVT drive belt, refer to ADJ 5.1 DADH Drive Belt Adjustment.– That the CVT roll is clean and rotates freely, refer to ADJ 5.4.NOTE: If necessary install a new CVT motor, PL 5.25 Item 9.• Go to the 05E DADH Feed Clutch Failure RAP and check CL05-025.• Make sure that the size of the documents are sensed correctly. Refer to the 05C Docu-ment Size Sensor Failure RAP.
