Printhead Gap
Adjusting the Head Gap
The head gap is the distance between the printhead and the platen roller.
When you use envelopes or multipart forms, you need to have a larger gap
than when using plain paper. Use the recommended head gap to ensure the
best print quality and easy paper feed.
To adjust the head gap, remove the access cover. Then move the lever on
the right side of the ribbon cartridge to the correct position for the type of
media being used as detailed in the following tables.

CAUTION!
Incorrect setting of the head gap can cause printhead damage
or ribbon jams. To avoid these problems set the head gap for
the type of media being used.
