List Of Messages
Solution
1. Power off the printer. Reseat the
twinax host data cable
connection and twinax I/O cable
connection at the CT board.
2. Disconnect the twinax auto-
termination cable from the printer.
Test the cable for the resistances
shown in Appendix A. If the
resistances are incorrect, replace
the twinax auto-termination cable.
3. Power on the printer. Send a print
job to the printer. Verify that all
other devices on the twinax line
are working properly. (Refer to
line problem determination
procedures, as recommended by
the host system.)
4. If the message is gone, the host
has reestablished communication
with the printer. If all other twinax
devices work properly and the
message still appears, replace
the CT board. Record the
message and return it with the
defective board.
