Checkstand Considerations
Careful planning of how the checkstand and 7870 work together can
improve flow and ergonomics. An evaluation of the checkstand
should take into consideration:
•
weight of the 7870,
•
ventilation,
•
service clearance to the 7870,
•
display clearance,
•
power on and off,
•
secure fit and mounting in the cutout for the 7870,
•
item diverter (optional),
•
adjustable plate (optional),
Ventilation Requirements
The NCR 7870 Scanner/Scale does not need an exhaust fan in the
checkstand provided
•
there is adequate convection air flow,
•
no other equipment in the checkstand raises the temperature in the
checkstand to more than 7° C (12.6° F) above the ambient
temperature, and
•
the temperature inside the checkstand does not exceed 40° F.
If the checkstand contains other heat producing equipment, forced air
may be needed to keep the temperature within the 7870’s operating
range. If forced air is used, air coming into or leaving the checkstand
MUST NOT enter or exit past the 7870.
