Periodically clean the Weight Guard system surfaces to ensure optimal functionality.
Several factors can impact Weight Guard performance after continued use.
Dirt, scratches, or other substances on the transmit/receive window on either side of the tower
Dirt or other substances on the platter surface
Dirt, scratches, or other substances on the retroreflector inlays on either side of the far edge of the platter
Damaged or peeling retroreflector inlays
Clean the Weight Guard as follows during regular cleaning of the MP7200 scanner, as well as when a Weight Guard warning or error code displays on the 7-segment display.
Wipe all Weight Guard surfaces with a damp cloth or Zebra approved cleaning agent. This includes transmit/receive windows, platter surface, and retroreflector inlays.
Wait two minutes while the system surfaces dry completely. If the warning or error codes clear, no further action is required.
If the warning or error codes persist, attempt a field calibration using the scale
0
button on the touch UI panel. Also perform a field calibration after replacing any parts of the Weight Guard system.
If field calibration fails (U39), check all Weight Guard surfaces for damage. A Weight Guard field calibration may compensate for minor damage. More significant damage, such as deep scratches to transmit receive windows, peeling or missing retroreflectors, or hard to remove substances require additional service to restore performance.
Wait a minimum of two minutes after cleaning to allow liquid cleaning agents to completely evaporate. Weight Guard function is not reliable when system surfaces are wet or damp.
