Soiling on paper The printer 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 printer, 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.)
