Notes on Wireless LAN connection
Because not all the combinations of the printer and wireless LAN devices have been checked for operation, the
operation of the printer in combination with all the wireless LAN devices is not guaranteed. Especially in the
ad-hoc 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
1 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 1 minute, and then reconnect to the printer.
 Where wireless LAN 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.
Notes on using the roaming function
When the roaming function is enabled, if you continue to use the printer in an area where the radio waves for
the access point that is connected to are weak, the printer will continue to search for an access point with
stronger radio waves, thus shortening the battery life.
