CHAPTER 9: Troubleshooting
9.5.7 P RINT -S ERVER O PERATION
The following is a list of some other problems that you may run into when using
the Ethernet to Twinax/Coax Print Server:
Problem: During the normal power up process, all LEDs on the top cover turn on
and do not turn off.
Resolution: This indicates a hardware failure. Contact Technical Support
Problem: During the normal power up process, both Mode LEDs flash together.
Resolution: This indicates a hardware failure. Contact Technical Support.
Problem: During the normal power up process, the Line Sync LED continues to
flash.
Resolution: The twinax or 3270-coax printer is not attached, not powered on, not
on-line, or has some other error condition that prevents the printer from
accepting print jobs. Check each of this conditions.
Problem: The print server flashes the Printer Error LED and prints on the attached
printer a description of the problem.
Resolution: The LED will blink when a data mismatch has been received by the
print server and a message about the error will print on the attached printer. This
condition requires the print server to be either reset from the PrintControl utility
or have the power cycled off and back on.
Problem: The Diagnostic Report indicates that the twinax printer is not “busy”
when data is received.
Resolution: The twinax protocol requires printers to report BUSY after a
command is received. Some faster IBM and compatible printers do not do this.
Using the PrintControl utility, take the Printer Ports/Emulations option, then the
Twinax Port, and finally on the Busy on Commands selection, choose No to disable
checking for BUSY.
