Adjusting the Printer Head Gap:

The size of the gap between the print head and the paper determines the
printing pressure. This affects the darkness and quality of the type. The
print-head gap also determines how smoothly the paper feeds.

Set the print-head gap correctly for the type of paper you are using, as
shown below.

CAUTION: If you do not correctly set the gap between the print head and
paper, you might damage the print head.

Standard, 20-pound paper: Position 3 (A mark shows this is the standard
                          setting)

Most 2-Part Copies:       Position 5 or 6

When you begin using a different thickness of paper, run a self test and
adjust the print-head gap until the print quality is good and the paper
feeds normally.

Notes:

* If the print smudges, the paper jams, or feeds abnormally, or the ribbon
  loosens or comes off the print head during printing, select a higher gap
  setting.

* If the print is too light or characters or parts of characters are 
  missing, select a lower gap setting.

Print-Head Protection:

If the print head becomes too hot, printing automatically stops. When the
print head cools, printing automatically resumes.
