Troubleshooting

Cause Solution Reference
The encryption key is incorrect. Check the encryption key of the wireless LAN access point
you want to connect is correct, and set the correct
encryption key.
When a same number is lined up in the encryption key, be
sure to press «OK» after inputting each number.
Example: To input 1233,
press «1» → «2» → «3» → «OK» → «3».
It is incorrect to press «1» → «2» → «3» → «3». In that
case, «1»«2»«d» is input, which is not the correct
encryption key.

The setting of [Security] does not
match the security of the wireless
LAN access point.* Above ③
Check the security (encryption method) of the wireless LAN
access point that you want to connect, and set it to keep
consistent.

Communication is not stable
Cause Solution Reference
The RSSI value is too small.*
Above ⑥
The signal strength is insufficient.
Put this machine in an unobstructed view position near the
wireless LAN access point. (The recommended distance is
30 m or less.)
Do not place an electric appliance (especially microwave
oven or digital cordless telephone) that emits weak
electronic waves near this machine.
It may be difficult to connect if there is a metal, aluminum
sash or reinforced concrete wall between this machine and
the wireless LAN access point.
-
The current frequency band is
congested.* Above ⑤
[Band] displays the current frequency band to which this
machine is connected.
This machine is compatible with the 2.4 Ghz/5.0 GHz band.
If the wireless LAN access point is compatible with the 2.4
GHz/5.0 GHz band, try changing the connecting frequency
band of the machine (or changing the SSID settings).

Able to connect to the access point but unable to communicate
Cause Solution Reference
The IP address is in the same
segment as the one on the wired
side.
Since the communication may be unstable if the wired LAN
and
wireless LAN are connected to the same subnet, please
connect to a different subnet.
-
The setting of the enabled default
gateway is wired LAN instead of
wireless LAN.
To communicate with a terminal outside the segment via a
wireless LAN, press the
scroll buttons on the operator panel
to select [Admin Setup] - [Network Setup] - [General Setup]
- [Enabling Default Gateway] and set it to
[Wireless(Infrastructure)].
In that case, the wired LAN cannot communicate with
terminals outside the segment.
*You can check from [General Information] - [Enabling
Default Gateway] in Network Information.
