Abstract: This disclosure provides printing systems, printing methods, and assemblies for decurling a sheet of print medium. Print media can include paper or other media that can exhibit some tendency to deform when damp or exposed to a certain degree of moisture or moisture. This deformation can be undesirable and can affect the image quality or the perceived image quality of printed matter. To increase the energy efficiency of the procedure for unrolling sheets that have undergone deformation and increase productivity, the following curl unrolling unit is applied, which includes a frame attachable to a sheet collecting tray at an outlet of a printing device, a first corner component mounted on a frame containing a first sloping surface to receive a first corner of a leading edge of a sheet of print medium issued by the printing device, and a second corner component mounted on the frame, comprising a second sloping surface to receive a second corner of a leading edge of the sheet of print medium issued by the printing device.

Abstract: There are provided a roll sheet conveying apparatus and a sheet conveying control method wherein it is possible to control motor driving for conveying a roll sheet at appropriate timing to keep constant the tension of the sheet to be conveyed without performing a special identifying operation. For this feature, a relationship between friction load torque on the roll sheet and the mass of the roll sheet is previously stored in a storing unit, whereby the moment of inertia of the roll sheet can be detected at appropriate timing during printing. As a result, the optimum tension of the sheet to be conveyed can be maintained by appropriately adjusting the driving control of a sheet feeding motor and a conveying motor without performing a special identifying operation.
