Abstract
Barcode readers with off-platter detection assemblies are disclosed herein. An example barcode reader includes a weigh platter and an off-platter detection assembly including a light emission assembly, a light detection assembly, and a controller. The light emission assembly emits a light along a first lateral edge of the weigh platter and the light detection assembly detects at least a portion of the light from the light emission assembly. The controller is configured to: receive a light detection signal from the light detection assembly; compare the light detection signal to a first signal threshold and a second signal threshold range; execute a first event if the light detection signal is less than the first signal threshold, indicating an off-platter event; and execute a second event if the light detection signal is within the second signal threshold range for a predetermined period of time, indicating a maintenance event.
