INTERRUPT UNUSED
VECTOR 00
This message is generated
when the controller board
gets an interrupt it does not
understand. The problem
can be created by electrical
noise, by a software
problem, or by a hardware
problem.
1. Cycle power. If this message
occurred once and never again,
you can ignore it. If the message
reappears or appears
consistantly check the grounding
of the printer. If the machine is
correctly grounded, replace the
controller board.
2. Power on the printer. Cycle
power. If the message appears,
suspect an application software
error. Request assistance from
your local support group. Install
the original controller board.

connection and the twinax I/O
cable connection at the

2. Disconnect the twinax auto-
termination cable from the printer
or from the last device on this
twinax port. Test the cable for the
resistances shown in the Main
Wire Harness Test Tables in
Appendix A. If resistances are not
correct, replace the twinax auto-
termination cable.
