WARNINGTake care during this procedure. Sharp edges may be present that can cause injury.
CAUTION
Ensure that E.S.D. procedures are observed during the removal and installation of the IOT
PWB and the NVM chip. Make a visual check to ensure that the pins are fully inserted, without
being damaged.
Use the appropriate tool to remove the NVM chip.

Replacement
If a new LVPS and base module is installed with the HVPS and IOT PWB transferred from
the failed LVPS and base module then perform steps 1 to 3.
If a new power and control assembly complete with IOT PWB and NVM has been
installed then perform steps 1 to 4. If the NVM has not been corrupted, it can be transferred from the IOT PWB on the failed
power and control assembly and installed onto the new IOT PWB. This will retain the orig-
inal machine configuration and NVM data for the IOT.
Figure 7, Ensure that the NVM chip is installed with the notch at the bottom. Improper
installation can damage the NVM.
Install the new power and control assembly with the original NVM chip on the IOT PWB
and perform steps 1 to 3.
CAUTION
Ensure the HT leads are correctly connected. Do not connect the female spade connector
between the male spade connector and the outer casing of the HT leads.CAUTION
Do not trap the harnesses when the power and control assembly is installed.
Perform the following:
1. Figure 7. Ensure that the bypass tray ribbon cable is routed correctly.

Switch off the electricity to the machine, GP 14. Disconnect the power cord. Electricity
can cause death or injury. Moving parts can cause injury.
WARNING
Do not attempt any repairs to the power cord or safety ground harness/conductor.
NOTE: Safety ground connections use green/yellow cables, or green cables with a yellow
stripe or band.
NOTE: Refer to PL 31.20 for identification of different connectors and terminal types.
The following steps identify the relevant procedures for repairing the various connectors con-
tained within the copier.
1. If wiring is damaged, use connector splicing blocks from the appropriate repair kit, PL

WARNING
Switch off the electricity to the machine, GP 14. Disconnect the power cord from the
customer supply while performing tasks that do not need electricity. Electricity can
cause death or injury. Moving parts can cause injury.
NOTE: Molex connectors have small black housings in single and double row form with minia-
ture square section pins and sockets.
1. If the damaged connector is located in the centre of a double row housing beneath the
latching clip, the latching prong will not be accessible to release the connector from the
housing. Therefore it will be necessary to disassemble the housing as shown in Figure 1.

WARNING
Switch off the electricity to the machine, GP 14. Disconnect the power cord from the

cause death or injury. Moving parts can cause injury.CAUTION
Amp CT connectors use in-line adaptors to connect housings together. Ensure that the correct
adaptor is used for each in-line connection (Table 1). Do not attempt to disassemble or repair
the in-line adaptors.
NOTE: There are two types of CT connector: insulation displacement connector (IDC) or crimp
terminal. Repairing crimp terminal CT connectors is performed by installing individual replace-
ment terminals with flying leads, connected to the existing wiring with connector splicing blocks
(removal steps 2 and 3). Repairing IDC connectors is performed by installing a complete
replacement housing with wires already fitted, connected to the existing wiring with connector
splicing blocks (removal steps 4 and 5). The replacement procedure is only applicable to crimpterminal connectors.
1. Identify the terminal type. Go to step 2 for a housing containing crimp terminals, or go to
step 4 for a housing containing insulation displacement (IDC) terminals.

WARNING
Switch off the electricity to the machine, GP 14. Disconnect the power cord from the
customer supply while performing tasks that do not need electricity. Electricity can
cause death or injury. Moving parts can cause injury.
CAUTION
Ensure that E.S.D. procedures are observed during the removal and installation of the IOT
PWB and the NVM chip. Make a visual check to ensure that the pins are fully inserted, without
being damaged.
Use the appropriate tool to remove the NVM chip
1. Remove the rear cover, PL 8.10 Item 1.
2. Figure 1, disconnect the PJs from the IOT PWB.
NOTE: 32-38 ppm IOT PWBs do not have PJ33 and PJ64.
3. Remove the IOT PWB (8 screws).
Replacement If a new IOT PWB and NVM has been installed, perform steps 1 and 2.
If the NVM has not been corrupted, it can be transferred from the failed IOT PWB and
installed onto the new IOT PWB. This will retain the original machine configuration and
NVM for the IOT.
Ensure that the NVM chip is installed with the notch at the bottom, Figure 1. Improper
installation can damage the NVM.
Install the new IOT PWB. Ensure the IOT PWB ground contact screw is tight and the
spade contact does not damage any components or tracks on the IOT PWB, Figure 2.
Ensure the contact faces are clean. Ensure the screw is bright plated and not black. Per-
form step 1.Perform the following:
1. Reconnect the power cord and switch on the machine, GP 14.
If necessary, reload the software set, GP 4. If the machine is fitted with a network control-
ler, the machine will automatically upgrade or downgrade the software when the machine
is switched on.
NOTE: After the software reload has been completed, the machine resets and gives a
message Restoring Configuration Settings. Do not switch off the machine or intervene
during this NVM transformation process.
