Troubleshooting
Cannot Print Properly through Wireless
Communication
The following are the causes of trouble may occur when printing through infrared communication
between a mobile phone and the machine. They do not apply to troubles when printing from a
computer over a wireless LAN.
For the trouble when printing through Bluetooth communication, refer to the Bluetooth User’s Guide.
Cause Action
The installation place, distance,
and/or angle is improper.
When printing through infrared communication, confirm that the infrared
communication ports on both the machine and the mobile phone are placed
to face each other at the proper angle and distance, and that there is
nothing to block the communication between them, and then try printing
again. The proper distance and angle for communication vary depending
on the specifications of your mobile phone and on external environment.
Place the machine within 7.87" / 20 cm from the mobile phone for proper
communication.
During infrared communication,
infrared rays were interrupted or
another infrared communication
device is operating nearby.
If infrared communication between the infrared ports of the machine and
the mobile phone is interrupted by any obstacle for ten and several
seconds or longer during printing, the paper on which data is being printed
is ejected and the machine is reset. Remove the obstacle and retry printing.
If an infrared communication device is operating nearby, interference can
occur and fail in printing the document to the end. While printing a
document through infrared communication, do not operate another infrared
communication device, such as a remote controller of a TV, nearby.
The version of the infrared
communication port being used is
not compatible with IrDA.
The infrared communication function of the machine is only compatible
with mobile phones with IrDA compliant infrared communication ports.
Printing through infrared communication cannot be performed by any other
types of mobile phones.
