Head up/down mechanism positions
The carriage moves to a higher position when
the mechanism is set to the right.
(For thick media)
Normally the mechanism is set to the
up position.
(For thin or normal thickness media)
Next, while raising the front of the carriage,
change the position of the right head up/
down mechanism.
TIP

The carriage position is 0.5 mm higher when both
the right and left head up/down mechanisms are set
to the horizontal position.
Generally, Normal is used for glossy and matte vinyl
chloride media, and High is used for tarpaulin and
FF media. If the media thickness exceeds 0.5 mm,
High should be used regardless of the media type.
Use also High even with thin media if it is severely
wrinkled or contains irregularities that may touch
the print head.
