Abstract
In order to mitigate image defects caused by unwanted disturbances as a carriage module travels from a continuous velocity transport module across a CVT ramp to a platen module, a bottom surface of the CVT ramp is recessed relative to bottom surfaces of the CVT glass and platen glass to facilitate a smooth transition as the CIS carriage passes the CVT ramp during scanning. An additional carriage button is also provided on the carriage surface to ensure that at least two carriage buttons are biased against the CVT-platen assembly at all times, thereby mitigating vibrational disturbance in the system during scanning motion. The carriage module may be a contact image sensor (CIS) carriage module, a Full Width Array (FWA) carriage module, or a folded Charged Coupled Device (CCD) carriage module.
