Chapter 6: NCR 7401/7890 Scanner Differences
The 7401 Scanner does not have a detector, but it does turn off the
motor and laser after a period of time (programmable). This period of
time is from when the motor and laser is first started until when they
are automatically turned off. This is called the Active Time. The Active
Time is set by default to 20 seconds for the 7890 Scanner; to 30 seconds
for the 7401 Scanner.
NCR OPOS and the FitClient platform can handle the lack of an
integrated motion detector by using the 7401's motion detector located
under the LCD screen. The NCR OPOS driver receives information
(events) from the motion detector on the front of the 7401 to determine
when the scanner should be started.

This detector, although good at detecting someone walking up
to the 7401, may not detect someone who has been standing in front of
the 7401 for a while and then presenting an item below the 7401
Scanner for reading.
After the Active Time period expires, if the NCR OPOS scanner driver
does not get another motion event, the motor and laser are turned off.
If a motion event is received during the Active Time period, the motor
and laser will continue to run and the timer is restarted. The
application using NCR OPOS should keep track of the motion
detection events (and the time since the last event) to ensure that the
scanner is running when the application is requesting scanner input. If
no motion events are received before the Active Time period expires,
and a transaction is still active, the application must either restart the
scanner or perform some other recovery procedure, such as asking the
customer if they still want the same service performed. These
procedures should be well designed and tested so that the customer is
not attempting to scan an item when the motor and laser are off.
The motion events are documented in the NCR OPOS Online Help file
that comes with the NCR OPOS software; the help file is also available
on the IPP web site (search for a Title containing OPOS). Use of the
motion detector without using the NCR OPOS drivers is not
recommended and is currently not documented.
