7 Troubleshooting

The programs should work properly if the procedures described above are
followed. Nevertheless, something unexpected could cause them to fail to
operate normally. This chapter explains how to diagnose any problems.
7.1 Troubleshooting the NDPS Printer Configura-
tion Module
7.1.1 Why does the "Authentication failed" message
appear?
This occurs only with the QMS (Queue Management Services) port handler.
The configuration utility requires an authorized connection with sufficient
privileges in order for it to add objects and link them together.
The Windows-based configuration does not login for you. Instead, it will
request that you login before configuring printer agents. If your login does
not have sufficient privileges, the "Authentication failed" message may
appear.
7.1.2 Why is a particular printer not found in the
"Discovered Printers" list?
This may be caused due to any of the following reasons.
• Loosened network cables — Check all cable connections and verify
the connections with the "ping" command.
• Incorrect IP address is configured on the printer — Make sure the IP
address is reachable from the client's machine. If the printer is located
in another subnet, remember to specify the default gateway (i.e.,
router address) on both the client's machine and the printer.
• Incorrect read community name — Provide a valid community name
for detection. Normally, "public" is a valid name.
