Abstract
A data reading system including one or more imagers and a lower main housing structure with a horizontal surface and a horizontal window, across which items to be read are passed. At least one or more of the imagers in the data reading system is a part of a top-down data reader having a generally downwardly-facing field of view projecting through a scan window and onto the horizontal surface and the horizontal window. The top-down data reader may be freely repositioned at a range of height positions and angular configurations for processing items of various dimensions. The data reading system may further include a calibration system for assisting in adjusting the field of view of the top-down data reader to ensure proper aim and focus of the top-down data reader after adjustment.
