7.3.1.
Cleaning the Ultra Sonic Sensors
Since the Ultra Sonic Sensors for Double Feed Detection
in the front area of the Scan Plane are fitted somewhat
lower, it is especially important for the lower sensors that
they tested at regular intervals for deposits and most
easily cleaned using the dusting brush (
see chapter
If the sensors are too dirty or there are residues on them,
this could lead to incorrect Double Feed Detections.
7.3.2.
Cleaning the Scan Areas
The Scan Areas for front and back side, as the respective
Scan Background, are covered dust-protected with
very scratch-resistant Glass Guides. Therefore surface
cleaning of the Glass Guides with the supplied Swiffer®
Dusters™ Cleaner Kit or a soft cloth is normally sufficient.
Should adherent residues be on the Glass Guides, these
should be removed with SCAMAX® Cleaning Solution
for Optics.
7.3.3.
Vacuum Cleaning Below the Scan Plane
As mentioned at the beginning of the main chapter, accrued dust and other impurities should be
sucked from the scanner at intervals basis (

)
.
Since most residues deposit at the beginning of the
paper transport path as experience has shown, the
area below the Scan Plane thereof is mostly affected.
In order reach this point, the Front Pressure Unit, the
area between feeder and scan areas, must be removed.
To do this, the Pressure Unit is lifted behind on the si-
de-mounted retaining brackets and then it is removed
completely from its holder. Since this is a metal part,
a small force is needed. Now, using the dust brush,
sweep the accumulated paper or ink dust and scraps
of paper, staples or the like from the visible areas and
vacuum clean. It should be ensured that the existing
connections are not detached or damaged by mistake
during the cleaning process. Then install the Pressure
Unit again by being taken with the brackets and first
lodged with the leading edge into their holder.
