Service Access Requirements
The scanner and scanner-scale have been engineered to allow performance of
all routine service and maintenance (such as “zeroing” and calibration) without
removing the scanner from the checkstand. Additionally all cable connections
made at the scanner can be connected and removed while the unit is sitting on
the countertop. The installer should provide service access to all remaining
cable connectors as well as the AC/DC Power Supply (if installed).
Recommended Power Installation
Since the typical grocery environment includes conveyor belts and electric
motors, care should be taken to ensure that the scanner has a supply of “clean”
power (power without excessive electrical noise).
Liquid Drainage
Select a checkstand design which allows fluids to flow through, and directs liq-
uids away from any electronic equipment or storage areas.
Should a liquid spill occur, ensure that moisture can flow through the check-
stand without pooling.
Leveling
Both flange mount and shelf mount scanners may require leveling during
installation to ensure the platter is flush or just below flush with the counter.
Each type is leveled using different methods:
• Shelf mounted scanners use built-in leveling screws that mount to the
support rail and can be adjusted as needed. These adjustable leveling
screws are adjusted from the top of the scanner with a slotted screw
driver, with the platter removed. They should be adjusted so the platter is
flush with the top of the counter.
• For a flange mount scanner, adjustment screws must be provided by the
user if leveling is required. The leveling screws should be installed where
shown on the counter cutout/ installation page (see
Counter
Cutout, starting on page 27). Similarly to the shelf mount scanner, the
flange mount scanner platter should be adjusted level to the top of the
counter.
Cable Routing
Placement of the scanner-scale should be planned to allow easy access to other
components, as well as optimize communication between the scanner, the POS
terminal and the optional Remote Scale Display. Note that cables may drop
straight down from the scanner’s connector panel, or may be routed along the
unit’s side using the hardware provided. Do not route interface cables near any
electrical motors or other sources of electromagnetic interference.
Remote Scale Display Placement
The customer, and checker in some instances, must be able to easily view and
read the Remote Scale Display (if one is present). Ambient light and mounting
height considerations are discussed later in this section.
