Cannot Connect through Wired or Wireless Connections
Issue Possible Cause Recommended Solution
I manually entered a
wireless IP address,
subnet, and gateway on
my printer, but it won’t
connect to my wired or
wireless network.
The printer’s network must be
reset after values are changed.
Reset the network by touching Menu >
Connections > Networks > Reset Network and
then touching the check mark to save the
changes.
An ESSID value has not been
specified.
1. For a wireless connection, specify the ESSID
value that matches the value used by your
wireless router using the following
Set/Get/Do command:
! U1 setvar "wlan.essid" "value"
where "value" is the ESSID (sometimes
called a network SSID) for your router. You
can look on the back of your router for a
sticker with the router’s default information.
If the information has been changed from the
default, check with your network
administrator for the ESSID value to use.
2. If the printer still does not connect, reset the
network by touching Menu > Connections >
Networks > Reset Network and then
touching the check mark to save the changes,
and then power cycle the printer.
The ESSID or other value was
not specified correctly.
1. Print a network configuration label and verify
that your values are correct.
2. Make corrections as necessary.
3. Reset the network by touching Menu >
Connections > Networks > Reset Network
and then touching the check mark to save the
changes.
