Time spent attempting to resolve these problems might not be covered by the Hewlett-Packard warranty. Refer the customer to the network administrator for assistance in troubleshooting network problems. Note Test message After the printer is installed, verify communications between the printer and the IBM-compatible computer. Enter the following at the DOS prompt: C:\DIR>LPT1 ENTER (for printing to parallel port #1) The printer should print a directory listing of the C: \ directory. Some Windows operating systems do not run true DOS. Consequently, printing the directory may not accomplish a true test of the communication between the printer and the computer. Note EIO troubleshooting If the printer has been turned on for at least 10 minutes, it will not recognize a LAN cable plugged into the Jetdirect server until you turn off the printer and then turn it on again.

Bad packets, framing errors, unsendable packets, and collisions should be minimal. If a high percentage (greater than one percent) of these occur, contact the network administrator. All of the statistics are set to zero when the printer is turned off. q The "Novell Status" block should state the Novell printer server name to which the printer is connected. If the node name reads "NPIxxxxxx" (xxxxxx=last six digits of the EIO's LAN address), the EIO card has not been configured for a Novell server. This could indicate that the card is operating under an IPX protocol other than Novell. Consult with the network administrator if the node name is not present. q In the TCP/IP protocol block, the default IP address is "0.0.0.0." It is acceptable to operate the printer with this default address. The error message "ARP DUPLICATE ADDRESS" might appear in this block. This is also 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 printer. 226 Troubleshooting ENWW

Communication troubleshooting

Communications check

Note

Communication problems are normally the customer’s responsibility. Time spent attempting to

resolve these problems might not be covered by the Hewlett-Packard warranty.

Refer the customer to the network administrator for assistance in troubleshooting network

problems.

Test message

After the printer is installed, verify communications between the printer and the IBM-compatible

computer. Enter the following at the DOS prompt:

C:\DIR>LPT1

NTER

(for printing to parallel port #1)

The printer should print a directory listing of the C: \ directory.

Note

Some Windows operating systems do not run true DOS. Consequently, printing the directory may

not accomplish a true test of the communication between the printer and the computer.

EIO troubleshooting

Note

If the printer has been turned on for at least 10 minutes, it will not recognize a LAN cable plugged

into the Jetdirect server until you turn off the printer and then turn it on again.

Before attempting to troubleshoot a network problem or notifying the network consultant of a

problem, always print a configuration page.

See the

HP Jetdirect Print Server Software Installation Guide

for detailed explanations of

network issues (go to http://www.hp.com/go/Jetdirect).

Jetdirect configuration

●

If the EIO Jetdirect card has started successfully and completed its internal diagnostics, the

I/O CARD READY

message appears on the Jetdirect configuration page. If communication is

lost, an

I/O NOT READY

message appears followed by a two-digit error code. See the

Jetdirect Network Interface Configuration Guide

for further details and recommended action

(go to http://www.hp.com/go/Jetdirect).

●

The “Network Statistics” column indicates that network activity has been occurring. Bad

packets, framing errors, unsendable packets, and collisions should be minimal. If a high

percentage (greater than one percent) of these occur, contact the network administrator. All

of the statistics are set to zero when the printer is turned off.

●

The “Novell Status” block should state the Novell printer server name to which the printer is

connected. If the node name reads “NPIxxxxxx” (xxxxxx=last six digits of the EIO’s LAN

address), the EIO card has not been configured for a Novell server. This could indicate that

the card is operating under an IPX protocol other than Novell. Consult with the network

administrator if the node name is not present.

●

In the TCP/IP protocol block, the default IP address is “0.0.0.0.” It is acceptable to operate

the printer with this default address. The error message “ARP DUPLICATE ADDRESS”

might appear in this block. This is also 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

printer.
