● The Left Support encloses the Rewinder Motor and Encoder, containing a set of gears that transmit the Rewinder motion to the spindle. There is a V-shaped spring to load and fix the spindle in position. ● The Right Support holds the spindle in position to rotate over passive rollers. In the T520, the right support also contains the dampers for the roll cover opening movement control (the internal dampers perform a braking action preventing sudden movement during the opening operation). NOTE: The right support for the T120 models does not contain dampers.
The T120 and T520 have two different assemblies from the factory, nevertheless both can be replaced by the damper option of T520 (identical from the external point of view), and there is only one service part available. ● The spindle is designed to hold the paper rolls, and receive the motion from the rewinder gear in the Left Support. It consists of a central bar and two hubs; the right hub is fixed to determine the right-side loading position of the paper, and the moveable left hub adjusts to the width of the paper. ● The Roll Cover (T520 only) shields the roll from dust. NOTE: The Roll Cover is a passive part, with no sensor: the printer does not know its status.
Electronics The Rewinder Motor and Encoder system are directly controlled by the Main PCA. The paper output system Functionality The system ensures that the printed paper follows a controlled path and acquires a certain shape in order to be delivered properly to the user. It also has a cosmetic function. The system includes a set of three telescopic trays, which are extended to collect the cut-sheet paper printed from the Multi-Sheet Tray. ENWW Subsystems 11
