The components that needed frequent operation
were placed, as far as possible in front of the cashier to
reduce the twisting of the torso and neck. The width
and depth of the laser scanner was reduced to
accommodate the printer and code catalogue right in
front of the cashiers. The reduced width scanner
improved the cashiers’ reach over both conveyor belt
and the bag handling area. A deflector was provided on
the conveyor belt to ensure that the products are within
the maximum reach of the cashiers. The original
product bin handling requirements at the left of the
cashiers was eliminated and was replaced by plastic bag
hangers at appropriate height and location. The superimposition
of the normal and maximum horizontal and
vertical working areas on the checkstand drawing
facilitated the determination of the size and the
placement of the checkstand components (step 8).
