Interface troubleshooting
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 7-10, 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 an HP JetDirect configuration
page. If the message “I/O CARD READY” does not appear on the configuration page, see the
troubleshooting section of the HP JetDirect Print Server Software Installation Guide.
If the host system and printer still are 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.

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.
