8-2 Chapter 8: NCR 7401 7890/7892 Scanner Differences
Starting the 7401 Scanner Motor and Laser
The NCR 7890 and NCR 7892 Scanners have a built‐in detector that
senses when an object is in front of the unit. When an object is detected,
it turns the laser and motor on so it can scan. This detector is provided
so the scanner can be put into a low‐power‐consumption state when
the unit is not in use, permitting the scanner to last longer and use less
power.
The 7401 Scanner does not have a detector, but it does turn off the
motor and laser after a programmable period of time called the Active
Time. This period of time is from when the motor and laser are first
started until they are automatically turned off. The Active Time is set
by default to 20 seconds for the 7890 and 7892 Scanner; to 30 seconds
for the 7401 Scanner.
NCR OPOS and the FitClient platform handle the lack of an integrated
motion detector by using the 7401ʹs 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.
Note: 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.
