Table 6. General Symptom List
NOTE: Power-on initialization is explained on page 227.
1. Power off the printer. Remove the paper guide or pedestal
top cover. Reseat all cable connectors on the controller
board, especially connectors P106 and P107.
2. Check the shuttle for electrical shorts (page 259).
3. If the printer has the CT board, verify that the user is
running CT emulation software. If the printer does not
have the CT board, go to step 7.
4. If the printer has the CT board, check that the user has
enough flash memory installed to handle the emulation
software. (See Figure 33 on page 298, and the Boot
Diagnostics Menu on page 217.) Install flash memory and
download emulation software if necessary.
5. If the printer has the CT board, make sure it is correctly
seated in the controller board.
6. Power on the printer. If the fans run but the printer does
not initialize, replace the CT board.
7. Power on the printer. If the fans do not run and the printer
does not initialize, do the power supply operational check
(page 264). If the power supply fails the check, replace it.
If it passes the check, go to the next step.
8. Power on the printer. If the fans run but the printer does
not initialize, replace the controller board.
9. Power on the printer. If the problem persists, replace the
shuttle frame assembly.
10. Power on the printer. If the problem persists, replace the
control panel and cable.
