Problem: The amber fault light comes on and stays on.
This indicates that the twinax interface PCB assembly has failed and is no longer
functioning. In this situation, call for service.
Problem: The green online light stays on or flickers as it should, but the printer
does not print.
This indicates that the connection between the host and the twinax interface is
good, but that the host is sending bad printer commands. Check the printer
commands for errors. Correct any error you find and try again. If the printer
still does not print, try examining the data the twinax interface is receiving from
the host. Refer to "Printing unprocessed data" on page 33 for more information.
Problem: The green online light goes out and the twinax interface stops
communicating with your host system.
This problem has several possible causes:
• The twinax cable has become disconnected. Check twinax cable connections
at the host and all twinax devices including the printer twinax interface.
• The twinax cable has been terminated before the end of the cable or has been
unterminated. Check the last twinax device for proper termination; check all
other twinax devices to see that they are unterminated.
• Another twinax device has the same address as the printer twinax interface.
Check addresses of all other twinax devices (especially those added after the
printer twinax interface). Change addresses that conflict with the printer
twinax interface.
• The host has broken off communications with the twinax interface. Check
the program and the host configuration, making certain that the host is
ignoring the twinax interface.
