PROBLEM SOLVING TASKS
Figure 12-34. Boot button on the operator control panel
3. Reenter the BOOT command.
If the system still does not boot, call for service.
Printer does not respond to system controller
If the printer control console displays PRESS CONTINUE TO
RESUME PRINTING, but the printer does not respond when you
press the Continue button, or if the printer does not respond to
directions from the PC UI or the system controller keyboard
(non-U.S markets only), they may have lost communication with
each other. Use the following procedure to restore the
communication between the system controller and printer.
1. Press the Continue button on the printer control console, if
directed to do so.
If the printer responds and resumes printing, do not follow
the rest of this procedure.
2. If the printer does not respond and resume printing, either:
• Enter the RESET command.
• Select the Reset task from the Job Control menu of the
PC UI.
(Refer to the “Reset” section of chapter 5, “Job control
tasks.”)
3. Enter the PSC (printer subsystem controller) command. This
should put the printer back in communication with the
system controller.
Note: Ask your Xerox service representative to change this
command to a Logon Level 2 if not already done.
Otherwise, you will not be able to access it.
4. Retry the command to which the printer would not respond
earlier. If it still does not respond, tell your supervisor or a
systems analyst.
