Explanation
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.
The printer detects a twinax
protocol communications
error and reports the error.
Power off the printer.
Disconnect the AC power
cord from the printer. Check
the twinax host data cable
and twinax I/O cable
connection at the expansion-
CT board.
List Of Messages
Solution
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.
1. Reseat the twinax host data cable
connection and the twinax I/O
cable connection at the

termination cable from the printer
or from the last device on this
twinax port. Test the cable for the
resistances shown in the Main

termination cable.
