Poor Dot Positioning If poor dot positioning occurs, the horizontal dot alignment has to be
performed by an authorized technician.
Characters On The Screen Don’t Match The Printed Characters Many graphics characters
and special symbols are produced by different ASCII codes on each make of computer and printer.
Compare the character set charts in your computer manual with the printer character sets.
You Selected A Printer Driver In Your Application Program But The Codes Don’t Do The
Right Thing (Or Anything) On The Printer Contact your software manufacture to check if a
driver for your printer is available.
The Paper Jams Frequently When Using Continuous Forms Make sure that the incoming and
outgoing paper is straight. Be sure that the incoming paper is not sticking.
The Paper Jams When Doing Reverse Paper Feeds
Be sure that the lid is shut correctly. Don’t
tear off continuous forms while you are printing. With wider paper the right edge of the first page
may not be flat against the platen. Increase the top margin or advance to the second sheet before
you start printing.
