Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
Remove all documents from the DADH.

Perform the steps that follow:
• Check the DADH CVT motor drive belt, PL 5.25 Item 11 .
• Check the DADH CVT motor tension spring. Make sure that the DADH CVT motor
drive belt tension is correct,
ADJ 5.1 .
• Check the CVT roll pulley, PL 5.25 Item 17 .
If necessary, install a new DADH CVT roll, PL 5.25 Item 5 .
The fault only occurs in duplex mode (fault code 05-352-00).

Go to the
Final Checkout .
NOTE: The exit roll idlers remain lowered for 30 seconds.
Enter dC330 code 05-100 to check the DADH duplex solenoid, SOL05-100. Energize SOL05-
100 to lower the exit roll idlers, PL 5.35 Item 6 . The exit roll idlers lower.
Y N
Refer to
WD 5.1 . Check SOL05-100.

• Lower baffle assembly, PL 5.30 Item 14 .
NOTE: During normal operation, the exit roll idlers remain raised (closed) in simplex mode. In
duplex mode, the exit roll idlers remain raised unless the document is longer than 280 mm (11
inches). 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 the
output tray. The feed rolls held the second document.

N
Go to the
05D DADH Feed Clutch Failure RAP.
The fault is caused if the DADH feed motor runs too slowly in reverse, refer to the 05C DADH
Motor Failure RAP. If the fault continues, go to the Final Checkout .
Final Checkout
Perform the steps that follow. Install new components as necessary:
• Check that the CVT roll is clean and rotates freely, refer to ADJ 5.4 .
• Check the DADH CVT sensor, PL 5.20 Item 12 is installed correctly.
• Check the takeaway roll static eliminator and ground harness, PL 5.35 Item 7 .
• Make sure that the DADH ground harness is connected correctly, PL 5.10 Item 11 .
• Make sure the feed motor drive belt tension is correct, ADJ 5.1 .
• DADH feed assembly, PL 5.15 Item 18 .
If the fault continues, make sure that documents correctly exit the previous sensor in the docu-
ment path. Refer to the
05-335-00 DADH TAR Sensor Failure RAP.
