14-730 Scanner Application Card Failure RAP
14-730 There is no response or an incorrect response to the command issued by the scan ser-
vice.
Procedure
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.
Perform the following:
1. Switch off the machine, then switch on the machine,
2. Check that the harness from PJ152 is not routed under the single board controller PWB. If
the harness was under the PWB, examine the harness sleeving for punctures or other
damage. If necessary, install a new DADH/power distribution PWB harness,
6. Route the new harness to the right, away from the single board controller PWB. If this
has caused a blown fuse F1 on the power distribution PWB, install a new power distribu-
tion PWB, PL 3.24 Item 5.
NOTE: This fault has been caused on a number of machines by bad routing of the DADH/
power distribution PWB harness PL 3.24 Item
