Initial Actions
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.
• Switch off the machine, then switch on the machine, GP 14.
• Check the fault history file for other 03-xxx fault codes. If the 03-xxx fault codes occur ran-
domly, the cause may be due to electrical noise. Go to the OF10 intermittent Failure RAP.
Procedure
1. Ensure all the P/Js on the IOT PWB, PL 1.10 Item 2 are correctly and securely con-
nected.
2. 03-395 Only: This fault can be caused by a poor ground on the duplex tray or a paper
path problem. Check the active fault list for an 08-XXX or 09-XXX. Go to the indicated
RAP.
3. 03-395 Only: This fault can also be caused by a paper guide in a paper tray being set to
the wrong paper size. Check the paper guide settings in the paper trays.
4. Perform the OF7 IOT PWB Diagnostics RAP.
5. Reload the software set, GP 4, Machine Software.
NOTE: The supply harness is a flying lead that is a part of the LVPS and is not spared
separately.
6. Go to Flag 1. Check the voltages. As necessary, refer to:
• 01G +24V Distribution RAP.
• 01F +12V Distribution RAP.
• 01E +5V Distribution RAP.
• 01D +3.3V Distribution RAP.
• 01B 0V Distribution RAP.
7. As necessary, install new components:
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed, PL
1.10 Item 2.
• LVPS and base module, PL 1.10 Item 3.
8. 03-396 Only: If necessary, go to the 04A Main Drive Motor and Photoreceptor Motor RAP.
Perform the photoreceptor motor checkout.
