Modification of the thickness gauges
Application procedure of Teflon tape
1. Clean the surfaces of the thickness gauge using alcohol, and make sure no dirt or contamination remains on the
surfaces.
2. Apply Teflon tape on the thickness gauge as shown below.
Figure 3-4. Modification of Thickness Gauge (1)
The Printhead of this printer has an integral structure of the Printhead Cover and
Printhead nozzle surface. Therefore, if the thickness gauge touches the nozzle surface in
the same way as performed in the traditional procedure, the nozzle surface may be
damaged. When performing the PG Adjustment or checking the platen gap, make sure
to apply Teflon tape (thickness: 0.08 mm) on all the thickness gauges used for the
adjustment or check in advance.
Use commercially available Teflon tape of 0.08 mm in thickness.
When applying Teflon tape on the thickness gauges, make sure no bubbles or foreign
material remain under the tape.
