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.
