setting in the ASF
paper
with the longer
side down, the LF
roller cannot catch
the paper,
preventing paper
feeding.
The edge of paper
rises due when
paper is curled,
causing the ink
cartridge to rub
against the printed
surface of paper.
When borderless
printing is
conducted
continuously, ink
mist attaches to the
ribs on the platen,
and is transferred
to the backside of
the following
paper.
When the paper
end comes off the
pinch roller,
printing is
performed without
the paper being
held, preventing
the ink drops from
being ejected in the
correct positions,
resulting in
unevenness.
As the print media
slightly slips while
being fed by the
LF roller, printed
areas overlap,
causing the
problem.
