Adjusting the Printhead Pressure
The printhead pressure can be changed with the screws (1a) and (1b) at the inside and outside of the printhead.
Increasing the head contact pressure leads to an improvement of the print image density on the corresponding side
and to a shifting of the ribbon feed path in the corresponding direction.

Notice!
At A8+ also use the screw on the middle plunger for the adjustment.

Adjusting the printhead pressure
Turn the adjustment screws (1) counterclockwise until turning becomes perceptibly easy.
The heat level is to be reduced in the printer configuration until the print image is only barely recognizable. Under
these conditions, inaccuracies become clearly visible during adjustment.
Create print samples with the test function
Test grid
(
Configuration Manual) or a similar print pattern.
Adjust the adjustment screw (1a or 1b) clockwise in small increments on the side with the weaker print image until
the print image is even across the entire width. At A8+ include the screw on the middle plunger to the adjustment.
It may happen that you must turn the adjustment screws in an alternating fashion, resulting in a print image which
is too light overall.
For A4+M printer move the plunger to the A4+M standard position (22 upper graduation
operator's manual) and
repeat the test print. Possibly rerun procedure and adjust new.
When the print image is set evenly, continue with setting of the transfer ribbon feed path
