A sheet stacking device is provided with a hopper unit configured to stack a sheet, a feeding unit configured to feed out the sheet to the hopper unit, a distance detection unit configured to detect an inter-sheet distance, in the vertical direction, between a rear end portion of the sheet that is preceding and a tip end portion of the sheet that is subsequent, and an output unit configured to output a behavior stabilization command for the sheet based on the inter-sheet distance.

A post processing device includes: a processing tray that supports media on which post processing is performed; a post processing section configured to perform post processing on the medium supported by the processing tray; and a blowing section configured to blow air at the medium supported by the processing tray, wherein a control section for controlling the blowing section sets a blowing amount by the blowing section to a first blowing amount when the number of sheets of medium supported by the processing tray is less than a predetermined set number of sheets and sets a blowing amount by the blowing section to a second blowing amount, which is larger than the first blowing amount, when the number of sheets of medium supported by the processing tray is equal to or greater than the set number of sheets.

A media handling assembly contains a transport path for driving a document sheet downstream in a process direction. A first side edge extends lengthwise along the process direction. A registration guide edge extends lengthwise along the process direction and is situated opposite the first side edge. The media handling assembly includes at least one nozzle that is arranged proximate the first side edge. The at least one nozzle selectively discharges an airstream transverse the process direction towards the registration guide edge. The airstream drives the sheet against the registration edge guide for side registering and deskewing of the sheet.

This disclosure provides methods, components, devices, and systems for providing positioning and alignment of raw stock sheets during the manufacturing process. Some aspects, more specifically, relate to detecting a position of a raw stock sheet lifted from an initial position using proximity sensors and realigning the sheet to a desired position. Current techniques can cause misalignment or damage to sheets during placement. In some aspects, a raw stock sheet can be analyzed by a plurality of sensors to accurately and consistently place raw stock sheets from an initial position to a desire position for downstream manufacturing processes.
