6.15.1 Common to LAN/wireless LAN interface

When opening or closing the print data port (Port 1024) or the status port (Port 1025) or the sending and receiving port
(Port 9100), 150 msec to 200 msec interval is necessary between closing the port and opening the port again. If the
time interval after closing the port is too short, it may cause double connection. Double connection means that the
connection request "CONNECT" is sent to the port (Port 1024, Port 1025 or Port 9100) already connected (CONNECT
(Socket OPEN)). In this case, this connection request will be rejected "Socket CLOSE". When receiving request of
double connection, the printer responds to the request for disconnection (Socket CLOSE).

6.15.2 Wireless LAN interface

1) Communication distance and transmission speed between the host and the printer(wireless LAN board) varies
depending on the wireless LAN operation at the used environment.
2) When using the printer in the Infrastructure mode, it is recommended to use it at a wireless LAN field intensity
display of level 3 (see the
3) Communication data may be lost when wireless LAN environment is not adequate due to mobile use of the printer
or ambient conditions.
4) Please set the frequency of channels in each group are different for more than "5 channels" when multiple
wireless LAN network groups are neighboring.
Example) When the channel of the group 1 is "1", set the channel of the group 2 for "6" or later.

6.15.3 LAN interface

1) Connecting and disconnecting LAN cable while the printer is connecting to the PC may result in communication
failure. Please avoid connecting or disconnecting the cable while the printer is ON. In the case of communication
failure, restart the printer.
