RAP 7.50 Error Codes

Power On Diagnostics (POD) Failures
Insure that the Test LED is functioning properly. The Test LED can be viewed through a small hole
located in the right of the RJ45 Connector or to the left of the USB Connector on the System Controller.
• When printer power is applied, the Test LED will glow to indicate the start of the "Power On
Diagnostics" (POD) tests. At the successful completion of the Power On Diagnostics, the LED will
go off then glow again for one second, the go off.
• If a fault condition occurs during one of the "Power On Diagnostic" tests, that test is immediately
halted and the LED will flash a sequence that identifies the halted test. (Refer to Table 7.50.1
Diagnostic LED Flash Sequence Table.)
• If the LED does not glow or glows continuously, perform the following:
1 Switch OFF the printer.
2 Remove the System Controller. Remove all option/peripheral components from the System
Controller.
3 Reinstall the System Controller ensuring proper seating, and switch on the printer.
4 The diagnostic LED functions properly.
Y: Reinstall the option/periperal components one at a time and retest.
NOTE: If the LED still does not function properly, check the +5 VDC to the System Controller PWB
before replacing the System Controller PWB.
N: Replace the System Controller PWB.
