Problem The printer does not print when the computer sends data. Solutions 1 Is the SEL light on? If not, press the SEL key. 2 Check that the interface cable is securely connected to both the printer and the computer. 3 If you have the optional serial interface board installed, check to be sure that it is firmly seated in the printer. Problem I'm getting strange symbols, incorrect fonts, etc., when I try to print a document. Solutions 1 Check to be sure that the printer driver you have selected in your software matches the printer emulation. • Press SHIFT and SEL keys, then press GROUP key. • This will print a line showing the emulation you have selected. 2 If you have embedded any printer commands in your software, check to be sure that you entered them correctly.
