F-120 1K Lcss Pwb Damage Rap - Xerox WorkCentre 5687 Series Service Manual

11F-120 1K LCSS PWB Damage RAP

Use this RAP to determine the cause of damage to the 1K LCSS PWB, so that the cause can
be repaired before a new 1K LCSS PWB is installed.
Procedure
The 1K LCSS PWB can be damaged by a component connected to it going short-circuit. If a
new 1K LCSS PWB is installed and power applied to the machine, the new 1K LCSS PWB will
be damaged in the same way. The cause of the damage must be found by following this proce-
dure.
WARNING
Switch off the electricity to the machine, GP 14. Disconnect the power cord. Electricity
can cause death or injury. Moving parts can cause injury.
Remove the 1K LCSS PWB and inspect the components shown in Figure 1 for damage. The
damage to the component may be in the form of a crack, a small crater or a burnt patch. Refer
to Table 1 to locate the component causing the damage to the 1K LCSS PWB.
