Troubleshooting And Maintenance; Diagnosing The Problem - Epson LQ-800 User Manual

Troubleshooting and Maintenance

This appendix presents solutions for possible problems, explana-
tions of the LQ's advanced features, and maintenance tips.

Diagnosing the Problem

If the printouts from your LQ are not matching the document
you've prepared on your computer, you'll need to set up a test docu-
ment.
When you set up a test document on your computer, include the
symbols #, [, \, ], and {, because of their variation in the different
character sets. Also include numbers, punctuation marks, symbols,
carriage returns, and upper and lower case letters.
Now print the document. First check page B-4 to see whether the
LQ is printing the correct character set. When delivered, the LQ is set
to print the USA character set. If it's not printing the USA character
set, determine which character set it is printing. Then consult Appen-
dix A on DIP switches to find how to select the correct character set.
If the printout shows other problems, such as one line printing on
top of another, or too much space between lines, consult the following
list. The statements on the left list possible problems; the recommen-
dations are listed on the right.
