Abstract: A media transfer system comprising a media drive component and a vent. The media drive component supports and transfers a media in a drive direction. The vent directs air flow towards the leading edge of the media in the drive direction to exert a separating force on the leading edge of the media, the separating force acting on the media away from the media drive component.

Abstract: In an example, a print apparatus includes a controller and a printing unit. The controller may control the printing unit to print a media sheet with at least one indicia indicating an intended location of a fold line, wherein the media sheet is to be folded along the fold line. The controller may be to control the printing unit to print the at least one indicia to provide an offset gauge such that, when the media sheet is folded along a formed fold line, the indicia provides an indication of an offset between the intended location of the fold line and the formed fold line.

Abstract: Examples of a method for detecting misalignment cause a printer to print a calibration pattern on a recording medium sheet. The calibration pattern includes graduated measurement scales positioned so that: when the calibration pattern is printed without misalignment on a recording medium sheet of predetermined dimensions, matching graduations of plural measurement scales in the calibration pattern are printed at respective reference locations on the recording medium sheet that correspond to corners of the recording medium sheet (or to spaced positions along a line where folding of the recording medium sheet by a folding apparatus is intended to take place). When the calibration pattern is printed with misalignment on a recording medium sheet of predetermined dimensions, non-matching graduations of the plural measurement scales are printed at the reference locations on the recording medium sheet.
