Interface troubleshooting
This section contains information to help the user troubleshoot interface problems.
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 7-39.
Communications check.
Table 7-39. 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.
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 7-8. HP Color LaserJet 5500 printer
configuration page), 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.
CAUTION
HP LaserJet printers are not designed to work with mechanical switch-box products without
proper surge protection. These devices generate high transient voltages that cause
permanent damage to the formatter PCB. This circumstance is not covered by the Hewlett-
Packard warranty.
AUTOEXEC.BAT standard configurations
Use the following standard command.
Parallel DOS commands
Ensure that the AUTOEXEC.BAT file contains the following statements for parallel interface
communications:
