Adjusting the print head contact
pressure
The pressure unit ensures, that the print head
exerts an even contact pressure on the feed
roller. This contact pressure must be adapted to
different material widths and/or material
strengths. A contact setting knob (1) is fitted for
this purpose.
For details about setting the contact
pressure, refer to the user manual, topic
section "Setup", chapter "Print head".
The contact pressure can be set in 3 stages: a
sprung pressure plate clicks into the selected
position and prevents unintentional adjustment of
the contact pressure.
Adjustment
1. Remove the printers rear hood.
How to? - Read chapter Rear hood on
page 7 for details.
2. Set knob (1) to small setting
(see picture).
3. Turn the sliding block (2) at the head motor
to the print position.
4. Screw the coupling (3) onto the end of the
threaded bolt. Hang the spring balance (5)
onto the coupling.
5. Unscrew the nuts (4).
6. Pull at the spring balance until 8 N are
shown; simultaneously turn the nuts (4)
onto the threaded bolt up to stop.
7. Secure the nuts.
8. Remove the coupling.
