Adjustment of the Printhead

For optimum print quality, the line of heating elements on the printhead must be

parallel and aligned correctly to the print roller. This alignment has already

been performed in the factory. Nevertheless, it may become necessary to

adjust it.

A misaligned printhead causes a poor print quality which appears as described

below :

- the print image looks generally light, spotted, and irregular; or

- the print image appears uneven from one side to the other.

Adjust the printhead as follows :

1. You may leave the transfer ribbon (1) inside the printer, and simply poke

through it with your hex wrench.

2. Loosen the locking screw (2) on the printhead by half a turn. This will allow

for the required horizontal adjustment of the printhead.

3. By turning the two screws underneath (3) you may shift the printhead as

follows :

- The overall distance for adjusting is .1 in or 2.5 mm.

- By turning the screws clockwise, the printhead will be shifted backwards.

(about .02 in or .5 mm per turn)

- Adjust in small steps ! (quarter turns only)

- First, turn both screws constantly until at least one side of the print image

is optimum.

Following, adjust the screw which is located at the side of the label where

the quality is still poor.
