Abstract: Disclosed is an idler roller assembly for a printing apparatus. The idler rolling assembly includes a shaft, at least one idler rolling element connected to the shaft, the at least one idler rolling element having an inner surface and an outer surface and being connected to the shaft at a substantially center portion of the idler rolling element, the at least one idler rolling element being cylindrically shaped and having an axis substantially parallel to an axis of the shaft, and at least one radial control movement element connected to the shaft, the at least one radial control movement element having a radius selected to leave a predetermined gap between an outer edge of the at least one radial control movement element and the inner surface of the idler rolling element.

Abstract: When an instruction reception section receives an image forming instruction from an operator, a detector detects an toner image forming unit which performs an image forming operation in connection with the operator's instruction. A mode determining section determines which one of an image formation preceding mode or a sheet conveyance preceding mode is set for the toner image forming unit detected by the detector, and a drive controller controls drivings of the sheet conveying section and the image forming section according to the determined mode.

Abstract: A loader (1) for a printer for printing flat articles (2), this loader (1) which delimits a storage magazine (9) for the articles in the stacked condition being provided internally with a pivoting member (4) arranged to hold the articles (2) in bearing contact with a drive element (5) for discharging the articles (2) to be printed through an opening (7) provided in a wall of the magazine (1). This loader (1) is characterized in that the pivoting member (4) is provided with a counterweight (6) to form an assembly exerting a substantially constant bearing force on the article or articles (2) to be printed, this forced being self-positioning in the course of emptying the loader by moving along one of the articles to be printed in a direction generally opposite to the direction of expulsion of the articles from the loader.
