D. If you have a hub or multiport repeater, verify that the hub or repeater port is operating
properly by connecting the IntelliBar printer cable on a different port.
E. If you have a bridge or router located between the printer and the host computer, make
sure that the device is set up to allow the print server to send and receive data from the
host. For example, a bridge can be set up to allow only certain types of Ethernet ad-
dresses to pass through (a process known as filtering); therefore, such a bridge must be
configured to allow IntelliBar print server addresses. Likewise, a router can be set up to
pass only certain protocols, so be sure that the desired protocol can be passed through to
the IntelliBar AS Net print server. In the case of routers, also make sure that the proto-
col is routable (LAT, NetBEUI, and DLC/LLC are not routable).
If all of the physical hardware connections and cabling check OK, check the TCP/IP protocol
troubleshooting section below for additional causes of intermittent printer problems.
6.1.2 Intermittent Problems
If you are able to print configuration self-tests from the front control panel main controller and
through diagnostic settings for the print server and IPDS interpreter, but you intermittently have
problems printing jobs from the host, check the following:
A. If you able to print small jobs without errors, but large graphics jobs are distorted or in-
complete, make sure that you have adequate memory in your printer. IntelliBar printer
memory is expandable up to 10 Mbytes. You can check how much memory is installed
in your printer by printing a test page from the printer control panel that will list the in-
stalled memory.
B. If you have sufficient memory for your print job size, check the TCP/IP troubleshooting
section below for additional causes of intermittent printer problems.
C. If you have sufficient memory for your print job size, verify that you have ‘Page Protect
*ON set in the main control panel LJIII setup menu.
D. If you are seeing data shifting, character substitutions diagonal lines or overprinting, you
are attempting to on an area that is off the printer’s logical page. Remove all borders in
your print job. Verify that your line length does not exceed the width of the label you are
attempting to print.
6.1.3 Network Protocol Problems
Protocol problems generally fall into two categories: a TCP/IP protocol-related problem or an
OS/400 setup problem.
