Printer does not initialize NOTE: Power-on initialization is explained on page 125.
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 160).
3. If the printer has the expansion-CT board, verify that the
user is running CT emulation software. If the printer does
not have the expansion-CT board, go to step 7.
4. If the printer has the expansion-CT board, check that the
user has enough flash memory installed to handle the
emulation software. (See Figure 26 on page 191, and the
Boot Diagnostics Menu on page 118.) Install flash memory
and download emulation software if necessary.
5. If the printer has the expansion-CT board, make sure the
60-pin expansion adapter is correctly seated in both the
controller board and the CT board.
6. Power up the printer. If the fans run but the printer does
not initialize, replace the expansion-CT board.
7. Power up the printer. If the fans do not run and the printer
does not initialize, replace the power supply board.
8. Power up the printer. If the fans run but the printer does
not initialize, replace the controller board.
9. Power up the printer. If the problem persists, replace the
shuttle frame assembly.
10. Power up the printer. If the problem persists, replace the
control panel and cable.
