Firmware error on the controller
board.
1. Cycle power. Run the print job again. If the message appears,
download the emulation software again.
2. Remove the shuttle cover. Remove the paper guide assembly or
the pedestal top cover. Make sure the MPU cable (P/N 14H5329)
is not pinched. Check both the section of MPU cable coming from
the sensor and the intermediate cable extension that runs to the
controller board. (Refer to the Interconnection Diagram in Chapter
3.) Check the resistance of the MPU at connector P107. (Refer to
the Main Wire Harness Test Tables in Chapter 3.) Replace the
MPU if it fails the test. Adjust the gap between the MPU and the
shuttle motor flywheel to 0.010 inch (0.254 mm).
3. Check the shuttle for electrical shorts (page 252).
4. Power on the printer. If the problem reappears, the controller
board or microcode is suspect. Do the following:
5. Save the printer configuration values. (Refer to the
User’s
Manual
.)
6. Clear NVRAM (page 237).
7. Download and install the latest code from IBM First (page 231).
8. Power on the printer in download mode and load flash memory
(page 238).
a. If you encounter loading problems, go to the appropriate error
code for resolution.
b. If you encounter the failure or message that brought you to
this procedure, replace the controller board (page 319). After
replacing the controller board, DO NOT make the printer
READY, but proceed immediately to the next step.
9. Download and install the latest code from IBM First (page 231).
10. Power on the printer in download mode, and load flash memory
(page 238). If you encounter the failure after replacing the
controller board, reinstall the original controller board and contact
your DDS and Second Level Support.
