Soiling on paper The machine has
been used for a long
period of time with
the ASF cover
closed before
printing is
performed using the
ASF.
Due to ink mist
attached to the ASF
sub-pick-up rollers.
If printing is done
from the cassette
with the ASF cover
closed, ink mist is
kept inside the
machine, attaching
to the ASF sub-
pick-up rollers.
Since the sub-
rollers usually do
not contact the
paper, ink mist can
easily accumulate,
especially during
printing on small-
sized paper which
never contacts the
sub-rollers.
Clean the ASF sub-
rollers (see *3 for
details.)
