Troubleshooting communication interfaces
The following sections provide instructions for interface troubleshooting.
Check communications
NOTE Communication problems are normally the customer's responsibility. Time spent
attempting to resolve these problems might not be covered by the Hewlett-Packard product
warranty. Refer the customer to the network administrator for assistance in troubleshooting
network problems.
If the device is not connected directly to a Windows or MS-DOS-based host, see Troubleshooting the
EIO on page 500.
CAUTION HP LaserJet printers are not designed to work with mechanical switch-box products
that do not have correct surge protection. These devices generate high transient voltages that
cause permanent damage to the formatter. This circumstance is not covered by the Hewlett-
Packard product warranty.
Troubleshooting the EIO
If the device contains an optional HP Jetdirect print server, and you cannot communicate with the device
over the network, verify that the print server is operating. Print a configuration page (see
Use information
pages on page 76). If the Jetdirect card does not appear under "Installed personalities and options" on
the configuration page, reseat or replace the Jetdirect EIO card. See the troubleshooting section of
the HP Jetdirect Print Server Software Administrators Guide.
When the HP Jetdirect print server is installed correctly, print a Jetdirect page (this page automatically
prints when a Jetdirect print server is installed and a configuration page is printed). See
Use information
pages on page 76. The Jetdirect page contains valuable network-related information about the device.
Jetdirect page
The following information is on the Jetdirect page.
●
HP Jetdirect Configuration If the EIO Jetdirect card is installed correctly and the device completes
its internal diagnostics, the I/O CARD READY status message prints. If communication is lost,
an I/O NOT READY status message prints, followed by a two-digit error code. See the HP Jetdirect
Network Interface Configuration Guide for further details and recommended action.
●
Network Statistics This block indicates that network activity has been occurring. Bad packets,
framing errors, unsendable packets, and collisions should be minimal. If a high percentage (greater
than 1%) of these occur, contact the network administrator. All of the statistics are set to zero when
the device is turned off.
●
TCP/IP In this block, the default IP address is "192.0.0.192." You can operate the device by using
this default address. The error message ARP DUPLICATE ADDRESS might appear in this block.
This is an acceptable error code if the TCP/IP protocol is not being used. Check with the network
administrator to determine the correct IP address for the device. To configure the device's
IP address, go to the control panel EIO menu, select CFG NETWORK=YES, select CFG TCP/
IP=YES, and then select BOOTP=NO.
●
Novell/NetWare This block should state the name of the Novell printer server to which the device
is connected. If the node name reads "NPIxxxxxx" (where xxxxxx = the last six digits of the EIO
LAN address), the EIO card has not been configured for a Novell server. This could indicate that
