Verify that the printer is operating properly, is online, and supplies are loaded
correctly.
General Troubleshooting Information
Use the following information if your print server is not operating properly.
1. Verify that the printer is turned on.
2. Verify the print server is connected to the network.
The 9460 printer’s display shows the <T> symbol when the printer is connected and
ready to receive data.
The 9493 printer’s display shows the M or the n symbol when the printer is connected
and ready to receive data.
3. Print a test label. See Chapter 2, “Configuring the 802.11b/g and IP Settings” for more
information.
Use 2-inch supply or some information may print off the label.
If a label does not print, check the printer's display to see if it shows a receiving status.
Turn off the printer, wait fifteen seconds and then turn it back on.
4. On the test label, verify your IP and wireless settings.
Check the “Actual SSID” and the “Sig Strength”. Is the actual SSID correct? Is the
signal quality greater than zero? If the signal quality is 0, you lost connection with the
access point. If it is very low, you may be experiencing interference or are very close to
being out of range or an access point. A value of 100 is the best you can have for
signal quality. You can probably operate at a minimum of 60, but the number of retries
is likely to increase.
5. Telnet to the printer.
Note: After the print server has been reset, you may need to re-enable Telnet, or connect
serially.
Once you have verified connectivity, Telnet to the printer. This gives you access to
console operation of the printer. Press Enter (on your host) and enter access as the
password. Press Enter to by-pass the user name. Once here, you have verified
operation to the print server.
6. Ping the printer.
Pinging the printer tells you if it is “seen” on the network. If you cannot ping the printer, turn
the printer off and then on. Then ping every device in the path to the printer - access points,
routers, etc. Any device you cannot ping needs attention.
ping <ip address> (i.e. ping 192.0.0.192)
7. Verify connection to the data port by starting a Telnet session to the printer using port 9100
(i.e. Telnet aa.bb.cc.dd 9100).
Press
Ctrl-E on your keyboard. This sends an ENQ request. The printer responds with
three characters. Depending upon the Telnet being used, you may not see the first
character, as it is a hex 05 value. The other two characters are ASCII characters.
You see
A@
which means the printer is online and waiting. Alternatively, you can type
[J,2]
Note: The J must be capital.
