Abstract: A system for decurling a sheet which is being advanced in a predetermined path within a printing machine includes a mechanism for generating a flow of room ambient air. The decurling system further includes a mechanism for directing the flow of room ambient air onto the sheet. Moreover, the decurling system includes a decurler adapted to apply mechanical force to the sheet after the flow of room ambient air has been directed onto the sheet by the directing mechanism. Finally, a mechanism is included for rotating the sheet to advance the sheet to the decurler in a direction substantially perpendicular to the direction of the predetermined path.

Abstract: A development apparatus for developing images with magnetic toner particles contained in magnetic developer material. The development apparatus has a magnetic development roller and a device for removing a partial amount of magnetic chains of the developer material from the magnetic development roller. The device includes a first magnet generating a first magnetic field for standing the magnetic chains on a first end, and a second magnetic generating an opposite magnetic field for standing such chains on a second and opposite end. The device also includes a skiving plate that is positioned between the first and second magnetic fields.
