CHAPTER 9: Troubleshooting
Problem: When a 3270-coax printer is initially attached to the print server, the Line
Sync LED does stays off.
Resolution: The print server is shipped from the factory with a default setting for a
twinax printer. Use the PrintControl utility to identify that the attached printer is a
3270-coax type of printer. The LED will function properly afterwards.
Problem: The twinax printer repeats its self-test cycle.
Resolution: Only one twinax cable should be attached to the printer and to one
side of the “v” connector on the print server. If you have two twinax cables attached
to the printer and to both connectors on the “v” connector, remove one.
Problem: When attaching an IPDS printer using AnyNet, the AS/400 will configure
the printer device but won’t start the print writer.
Resolution: For LANRPCs with firmware version 1.43 or older, IPDS printers must
be connected to the AS/400 using PPR/PPD and not AnyNet. (Newer LANRPC
versions now support IPSD through AnyNet.) Following the directions in this
manual for setting printing IPDS over TCP/IP.
Problem: The print server’s Printer Error LED comes on, but the printer continues
to print.
Resolution: This indicates that an invalid character or command has been received
by the printer. The print server reports the error to the host and instructs the
printer to clear the error. It will continue printing. The LED remains turned on
during the rest of that print job as an indicator that an error was encountered. If
this condition continues, you may need to preform a DataCapture process and
print a diagnostic report. These should be forwarded on to Black Box’s Technical
Support group for analysis.
