Epson LQ-800 User Manual page 113

Problem
Nothing is printed
READY light flickers when you try
to print.
All the text is printed on the same
line.
D-2
Recommendation
Make sure the printer is switched
ON, and that the power source is
ON.
Check the connection between the
printer and the computer. Be sure
you are using the correct cable to
connect the computer to the printer.
Make sure the PAPER OUT light is
OFF If it's ON, reload the paper.
Check the indicator light on the
printer to see if the printer is on line.
Use the manual for your operating
system or applications software to
find out the command necessary to
configure the computer. Look for a
command like STAT or CONFIG-
the name depends on the operating
system you use.
If you are using the parallel inter-
face, either you have changed
switch 2-7 to OFF by mistake, or
you have an incorrect printer cable.
If you are using the serial interface,
the setting of the LQ's baud rate,
parity, number of bits per character
and number of stop bits may not
match the computer's settings.
Either change the configuration of
the computer or reset the DIP
switches on the LQ until the printer
and computer match. Refer to your
computer's manual or your dealer
for details.
This happens if there is no line feed
signal being sent from either the
computer or the printer at the end
of each line of text. To remedy the
problem, change the setting of DIP
switch 2-8 from OFF to ON.
