DMU Oil Blot
This function raises the Drum
Maintenance Unit up against
the Drum and then lowers
again. A Chase sequence is
then performs, which picks a
sheet of media from Tray 2
and moves it through the
paper path without printing.
The result is an oil print of the
contact of the DM Unit with
the Drum (appears about 2/3
of the way down the page).
This image should be viewed
in a timely fashion, as it will
tend to fade with time.
