Abstract
To prevent deformation to relatively stiffer sheets during flipping, while ensuring reliable holding of relatively weaker sheets, a method for stacking sheets received from a printer by a sheet flipping device includes at least one slot for receiving a leading portion of a sheet. The method includes determining a respective insertion depth parameter for a first and a second sheet, wherein the second sheet has a greater stiffness than the first sheet; inserting a length of the first sheet into the at least one slot in correspondence with its respective insertion depth parameter, followed by flipping said first sheet; inserting a length (D2) of the second sheet into the at least one slot in correspondence with its respective insertion depth parameter, followed by flipping said second sheet, wherein the inserted length of the first sheet is greater than that of the second sheet.
