Cannot Print Properly Through Wireless Communication The following are some causes of problems that may occur when printing via infrared communication. For problems when printing via Bluetooth communication, refer to the Bluetooth User's Guide. Cause Action The installation place, distance, and/ or angle is improper. When printing via infrared communication, confirm that the infrared communication ports on both the machine and the mobile phone are facing 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 computer and on the external environment. Place the mobile phone within 20 cm of the machine 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 about ten seconds or longer during printing, the paper on which the 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 the document may fail to print to the end. While printing a document through infrared communication, do not operate another infrared communication devices, such as the remote controller for a TV, nearby. The version of the infrared communication port being used is not compatible with IrDA. The infrared communication function of this 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. Chapter 11 Troubleshooting 111
