Notes on Wi-Fi connection
Because not all the combinations of the printer and Wireless LAN units have been checked for operation, the
operation of the printer in combination with all the Wireless LAN units is not guaranteed. Especially in the
adhoc mode, the printer may not operate normally, depending on the combination of the device to connect
with. Be sure to carry out evaluation of the operation before use.
Notes on use
When you initialize or change the printer settings, the printer is reset to reflect the settings. It may take about
one minute depending on the network settings or environment. Also, your application may indicate power off
during the time waiting for reset. In that case, wait for about one minute, and then reconnect to the printer.
Where Wi-Fi communication is in heavy traffic, your application may falsely recognize that the communication
is disconnected and indicate power off due to response delay. In that case, disable Power Save to improve the
trouble.
