6. Telnet to the printer.
Note: After the wireless module has been reset, you may need to re-enable Telnet.
Once you have verified connectivity, Telnet to the printer. (i.e.telnet aa.bb.cc.dd)
You see “Welcome to MonarchNet2 Enter Password:”
Type access as the password and press Enter. (access is the default password.)
The password is case-sensitive. You may not be prompted for a user name. Once here,
you have verified operation to the wireless module.
7. 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)
8. 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 will see
A@
which means the printer is online and waiting. Alternatively, you can type
{J,2}
Note: The J must be capital.
The printer responds with {J,0,0,””,””}.
No response means that the printer may have an open session to some other connection.
Either terminate the other connection or turn off the printer and turn it back on.
Troubleshooting Wireless Configuration Problems
1. Your computer’s wireless adapter and/or access point should be configured to match your
printer’s wireless settings.
2. The printer should be within range (90 meters or 300 feet) of your computer and away from metal
objects and other devices with radio signals (Bluetooth, 2.4 GHz cordless phones, and
microwaves).
3. Use infrastructure mode to connect through an access point.
Use Ad-Hoc mode to connect without an access point.
4. To use encryption or to password protect your wireless network, and your wireless adapter or
access point normally uses a password or pass-phrase instead of WEP, it should allow you to
enter 0x followed by a ten digit (for 40-bit or 64-bit WEP) or twenty-six digit (for 128-bit WEP)
key in hexadecimal format (0-9 or A-F).
5. Change the RF channel (Ad-Hoc mode only) to correct intermittent connection problems or slow
performance. Change it to at least three channels lower or higher than any other wireless
networks within range.
