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.

1.Your computer’s wireless adapter and/or access point should be configured to match your print server.

2.The printer should be within range (up to 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 WEP (Wired Equivalent Privacy) or other advanced security on your wireless network, temporarily disable the security on your computer in order to configure the print server. You may need to temporarily change the wireless mode of your computer to Ad-Hoc (802.11) mode to allow non-secure clients to communicate with each other.

Note: You many need to temporarily disable the security on your access point to set your computer to Ad-Hoc mode. When you are done configuring the print server, you can reenable the security on your computer and change the wireless mode back if necessary. You can also use a serial (wired) connection to configure the print server.

5.To use encryption or password protect your wireless network, and your wireless adapter or access point normally uses a password or passphrase 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).

6.Change the RF channel (Ad-Hoc mode only) to correct intermittent connection problems or slow performance. This can be done in the NetManager Wireless Configuration screen. Change it to at least 3 channels lower or higher than any other wireless networks within range.

♦To use TCP/IP, your computer and the print server should be on the same IP segment or can reach each other with a PING command from the host. The IP address you assign to the print server must be on the same logical network as your host computers.

♦If your print server is set to Auto or DHCP for obtaining an IP address, the print server’s IP address can change. Either configure your DHCP server to give the print server a permanent lease or configure the print server to be on a static address that does not conflict with any other address.
