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, move the colored lever (1) located to the
left of the ribbon cartridge to the correct position for the type of
media being used …
…as detailed in the following table:
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.
