the gap is
automatically
adjusted every time
fanfold paper or
manually-inserted paper is
loaded. When CSF is used,
automatic paper thickness
adjustment is performed
when the paper is first
loaded. Thereafter,
automatic paper thickness
adjustment is performed
when the next sheet is fed
if printing is not performed
within 3 to 4 seconds after
the paper is ejected.
The smaller the number, the
smaller the gap between the
head and platen.

Every click changes the gap by 0.04 mm.
The recommended gap for 70 kg 1P paper is at the 0 click
position in the FIX mode.
● AUTO mode
In the AUTO mode, the gap between the print head and
platen is automatically adjusted according to the paper
thickness. Since the most appropriate gap differs with the
type of paper, select the proper position between -2 and +5
according to the printing results.
● FIX mode
The gap between the print head and platen is fixed as
specified.
Select the proper position according to the paper type and
thickness by referring to the table below.
