Epson DFX-9000
1.2.1.6 Platen gap setting (SelecType)
The DFX-9000 platen gap is controlled by firmware, and is configured
through SelecType. There are two platen-gap setting modes: Auto and
Manual.
When set to Auto, the Automatic Paper Thickness Control (APTC)
mechanism measures the paper thickness whenever you load paper. The
distance between the head and platen is automatically adjusted for
proper printing according to the thickness of the paper.
Manual mode can be used to fix some print quality problems, especially
with multi-part and variable-thickness forms. The table below defines
the manual SelecType platen gap settings by paper thickness. When
using the Manual Platen Gap mode, the platen gap must be set to the
proper position as shown below.
