In some examples, a media stacker includes a drawer defining a chamber, and a plurality of moving elements to engage media sheets of different sizes as the media sheets are output from a system. The plurality of moving elements are to slide the media sheets to a target position in the drawer, and the plurality of moving elements are to disengage from the media sheets once the media sheets have reached the target position. A plurality of retaining elements are to engage the media sheets of the different sizes as the media sheets slide into the drawer.

Media stacker to receive media sheets

A sheet scanner comprises a sheet inlet on a front side, a scanned sheet outlet on a rear side, and a deflector to direct scanned sheets from the outlet towards the front side of the scanner, over the top cover thereof, and further comprises a stopper on the top cover, at the front side of the scanner and above the sheet inlet, to temporarily restrain the leading edge of a scanned sheet such that the sheet advances and folds over itself and beyond the stopper, the leading edge being released from the stopper when the sheet folded over itself and beyond the stopper pulls it downwards.

Sheet scanners

According to one example, there is provided a controller readable medium on which are stored controller readable instructions. The instructions are such that, when executed by a controller, perform the steps of commencing the printing of a print job on a media sheet, determining when about half of the media sheet ejected out of a printer media output is at the level of a stacker unit, activating a first array of fans to retain a portion of the ejected media sheet, completing the print job, and activating a second array of fans to blow the trailing edge of the ejected media sheet over the stacker unit.
