August 20072-122 WorkCentre 5687 Family05-345, 05-346Status Indicator RAPs05-345, 05-346 DADH Exit Sensor Failure RAP05-345 The DADH exit sensor does not detect the lead edge of the document within the correcttime in the forward mode.05-346 The DADH exit sensor does not detect the trail edge of the document within the correcttime in the forward mode.Initial Actions• Remove all documents from the DADH exit tray. Raise the DADH, remove all documentsthat are wound around the CVT roll.• Make sure that the customer has set the document width guides correctly.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.NOTE: On 32-38 ppm machines, the DADH exit sensor is actuated by a flag. On 45-87 ppmmachines, the DADH exit sensor is a reflective type sensor.Enter dC330 code 05-345 to check the DADH exit sensor, Q05-345, Figure 1. Raise theDADH. Activate Q05-345. The display changes.Y NGo to Flag 1. Check Q05-345.References:• GP 11 How to Check a Sensor.• P/J189, DADH PWB.• (32-38 ppm) 01D +3.3 Distribution RAP.• (32-38 ppm) 01B 0V Distribution RAP, refer to the 3.3V return.• (45-87 ppm) 01E +5V Distribution RAP.• (32-38 ppm) 01B 0V Distribution RAP, refer to the 5V return.Install new components as necessary:• DADH exit sensor, PL 5.30 Item 2.• DADH PWB, PL 5.10 Item 5.Close the DADH. Open the DADH top cover. Remove the DADH rear cover, PL 5.10 Item 1.Hold the top cover interlock switch closed. Enter dC330 code 05-030 to run the DADH CVTmotor, MOT05-030, Figure 2. MOT05-030 runs.Y NGo to the 05D DADH Motor Failure RAP.The CVT roll rotates.Y NPerform the steps that follow:• Check the CVT motor drive belt, PL 5.25 Item 11.• Check the CVT motor tension spring. Check the CVT motor drive belt tension, ADJ5.1.• Check the CVT roll pulley, refer to GP 7.If necessary, install a new DADH CVT roll, PL 5.25 Item 5.NOTE: The exit roll idlers remain lowered for 30 seconds.Enter dC330 code 05-050 to energize the DADH duplex solenoid, SOL05-050, to lower the exitroll idlers Figure 3. The exit roll idlers lower.Y NPerform the steps that follow:• Go to Flag 2. Check SOL050-050.References:– GP 12 How to Check a Solenoid or Clutch.– P/J181, DADH PWB and P/J205.– 01D +3.3V Distribution RAP.– 01B 0V Distribution RAP, refer to the 3.3V return.• Check the baffle assembly link arm, PL 5.30 Item 13. Make sure that the link arm isconnected correctly to the DADH duplex solenoid, refer to REP 5.5.Install new components as necessary:• DADH duplex solenoid, PL 5.30 Item 4.• DADH PWB, PL 5.10 Item 5.• Baffle assembly, PL 5.30 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.The exit roll rotates.Y NPerform the steps that follow:• Check the feed motor drive belt, PL 5.35 Item 5.• Check the feed motor tension spring. Check the feed motor drive belt tension, ADJ5.1.• Check the exit roll and pulley, PL 5.35 Item 6 and PL 5.35 Item 15, refer to GP 7.NOTE: If a new DADH input tray assembly is installed, perform the DADH Width GuideAdjustment, ADJ 5.3.If necessary, install a new DADH input tray assembly, PL 5.35 Item 1.The fault only occurs in duplex mode.Y NGo to Final Actions.NOTE: During normal operation, the exit roll idlers remain raised (closed) in simplex mode. Induplex mode, the exit roll idlers remain raised unless the document is longer than 280mm (11inches). The exit roll idlers raise and lower while feeding longer documents in duplex mode.Exit the diagnostics mode. Close the DADH top cover. Make two copies in duplex mode.Check that the second document is held in the feed rolls until the first document is fed into theoutput tray. The feed rolls held the second document.AA
