Abstract
Some examples of a document scanning system can include a scanner and a sheet output stacker. The stacker includes an upper surface configured to mate with the scanner configured to scan and transfer contents of a paper document. The stacker is configured to receive paper sheets from the scanner. The stacker includes multiple, upward extending interface housings positioned on the upper surface. The multiple interface housings are configured to be received in respective multiple receiving structures in the scanner, and are configured to mechanically and electrically couple the sheet output stacker and the scanner. The interface housings allow care-free electrical and mechanical pairing of a scanner to a stacker with no tools or adjustments. Simply positioning the scanner on the stacker such that the interface housings are aligned with the receiving structures results in the scanner being automatically guided into place and connected to the stacker through gravity.
