Troubleshooting
Problem: Nothing happens when I turn on the printer.
Solution: Check the power cable connection the outlet and
to your printer. If you are using a power strip,
make sure it is turned on, and that the fuse has
not blown nor the circuit breaker tripped.
Problem: The printer does not print when data is sent.
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 computer and the
printer.
(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.
Solution: (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.
Problem: I've installed a new ribbon and the printing is
smeared and streaked.
Solution: The ribbon shield is either loose or missing.
Remove the ribbon cartridge and check the clear
plastic ribbon shield: if it's loose, secure it in
place, if it is missing, find it and reinstall it.
