Infrared Menu (continued) Menu item Window Size Values Auto* 1 Transmit Delay The Window Size setting specifies the maximum number of infrared frames the printer can receive before it must send an acknowledgment to the host computer. If Auto is selected, the printer automatically sets the window size during power-on to maximize link performance. In most cases, Auto is the recommended setting. If you have trouble printing using the infrared port, changing the Window Size setting to 1 may resolve the problem. Auto* None 1...15 Max Baud Rate The Transmit Delay setting defines the amount of time the printer must wait before transmitting meaningful infrared data to the host computer, as well as the amount of time the printer requests the host computer to wait before it transmits infrared data. If Auto is selected, the printer automatically sets the Transmit Delay value during power-on to maximize link performance. In most cases, Auto is the recommended setting. If you have trouble printing using the infrared port, selecting a high Transmit Delay setting, such as 15, may resolve the problem. 2400 9600 19200 38400 57600 115200 576000 1152000* 4000000 *Factory default The maximum baud rate possible for both the printer and the infrared adapter is automatically set during power-on. However, if your printer is situated in a bright or highly reflective environment, you may experience intermittent communication problems. If you do, select a lower baud rate for the infrared connection. Menus 51
