Rep 9.1.1 Mcu Pwb - Xerox WorkCentre 7132 Service Documentation

REP 9.1.1 MCU PWB

Parts List on PL 11.1
Removal
To avoid personal injury or shock, do not perform repair or adjustment with electrical
power applied to the machine.
Static electricity may damage electrical parts.
Always wear a wrist strap to protect electrical parts from static damage. If a wrist strap is not
available, touch some metallic parts before servicing to discharge the static electricity.
Perform GP 4 Part 2 after each PWB is replaced. To maintain the integrity of the serial number
and billing data NEVER replace all of the PWBs at once. Replacing all three PWBs at once will
cause unrecoverable NVM corruption. If a PWB needs replacing, only replace ONE AT A TIME
and perform this procedure after each one is replaced. If the problem is not resolved, reinstall
the original PWB and re-enter the serial number (if necessary) before attempting to replace a
different PWB.
1. Whenever the MCU PWB is being replaced, go to GP 4 Replacing Billing PWBs and per-
form PART 1 to document Customer Settings and Machine Settings.
2. Switch off the power and disconnect the power cord.
3. Remove the ESS Cover, the MCU Cover and the Rear Lower Cover. (REP 10.2.1)
4. Disconnect the connectors from the MCU PWB. (Figure 1, Figure 2)
