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.
•
Make sure that the correct RAP is used. To identify the correct RAP to use, go to the
05-
330, 05-331
DADH Feed Sensor Failure Entry RAP.

Figure 2
. Check the operation of the feed yoke. Make sure that the feed yoke shaft is
under the clip. Make sure that the feed yoke spring is connected to the feed assembly and
to the feed yoke.
•
While the DADH feed solenoid is de-energized, make sure that the feed gates are locked
in the down position. Manually activate the DADH feed solenoid then make sure that the
feed 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 located
on the solenoid armature.
•
Clean the DADH feed sensor and the area around the sensor,
