Operating Your 7890 Scanner
The NCR 7890 Presentation Scanner
User’s Guide 1-3
Because your NCR 7890 scanner is a hands-free
presentation type scanner, it is much easier to use in
the retail environment. The scanner sits on the
counter and you present the bar code label to the
scanner. By using an optional Holder, you can hang
the scanner on a wall, or define a space on the
counter top, depending on the construction of your
checkout area.
Although the 7890 is a presentation scanner, there
may be times when the merchandise is too large to be
presented to the scanner. In these cases, you can pick
up the scanner and move it to the merchandise.
Because the scanner is very light, you can maneuver
it easily in these circumstances.
The design of your scanner permits it to sit on a
counter top in either a horizontal or vertical position.
However, you may want to use a Holder to prevent
the scanner from moving. The optional Holder kit
contains three different Holders: horizontal mount,
vertical mount, and hanging mount. You fasten the
Holders that you want to use to the counter top or an
adjacent wall. The Holders keep the scanner in a
position that is comfortable to use.
Your 7890 Presentation Scanner does not have an
On/Off switch. To minimize the amount of time the
laser is on, and to reduce wear in the unit, the
scanner contains circuitry that turns it off when not
in use. If you present a label to the scanner when it is
off, it detects the object and turns on. This occurs
with no noticeable delay in reading the label. After
several seconds of not detecting a valid bar code, the
scanner shuts off.
