Communications checks
Note Communication problems are normally the customer’s responsibility. Time spent attempting to
resolve these problems might not be covered by the product’s Hewlett-Packard warranty.
Refer the customer to the network administrator for assistance in troubleshooting network problems.
If the printer is not connected to an MS-DOS-based host, proceed to Table 7-40, Communications
check.
EIO troubleshooting
If the printer contains an optional HP Jetdirect print server, and you cannot communicate with the
printer over the network, verify the operation of the print server. Print a configuration page. If the
Jetdirect card does not appear under “Installed personalities and options” on the configuration
page (indicated by the arrow in Figure 7-4), see the troubleshooting section of the HP Jetdirect
Print Server Software Installation Guide.
If the host system and printer are still not communicating, replace the formatter PCB and the EIO
card and reconfigure the printer. If the problem persists, a protocol analyzer might be needed to
find the source of the problem.
Table 7-40 Communications check
Check Action
Is your computer configured to
the parameters described in
the configuration instructions?
These parameters are required to communicate with the printer.
Verify that the configuration of the computer's communications port
matches these parameters.
Note: If these parameters are not set properly, an error might display
on the control panel.
