2.3 Media Width Adjustment
To maintain even pressure distribution across media that is less than the width of the platen roller, the
printer requires a Media Width Adjustment. Whenever using media that is less than four inches wide,
proceed as follows:
1. Load media, then generate a batch of labels –
Non-Display models: Simultaneously press the
PAUSE +
FEED
buttons.
Display-equipped models: Select a quantity of Print Quality Labels (see the Operator’s Manual for
details).
2. While printing, loosen the Thumbscrew then move it to the left-most position. (The printing on the
labels should fade, as shown in Example 1, below.)
3. Move the Thumbscrew to the right until the labels contain a complete, even image (see Example 2)
and then tighten the Thumbscrew.
Example 1 – Over adjustment:
Too much adjustment produces an image that fades across the label. To correct
this, decrease the Media Width Adjustment.
Example 2 – Correct adjustment:
Proper adjustment produces a complete image, with even print contrast across
the label (see note below).
Note: Under-adjustment can cause ribbon wrinkling, lateral label movement, and
excessive wear on the printhead and platen roller.
