Abstract

Verfahren und Vorrichtung zur wirksameren Steuerung eines Papierstapels in einer Reproduktionsvorrichtung. Das Höhensteuerungsverhalten des Papierstapels wird parametrisiert, wobei zusätzliche Hebebefehle abgegeben werden, wenn festgestellt wird, dass derartige Inkremente erforderlich werden. Das Höhensteuerungsverhalten wird durch Abtasten von Daten während einer Abtastperiode parametrisiert, u.a. durch Inkremente, die durch Schalter initiiert werden. Bei der Parametrisierung werden zusätzliche Inkremente durch eine Quelle initiiert, die sich von der für die durch Schalter initiierten Inkremente unterscheidet, um eine wirksamere Steuerung des Papierstapels zu ermöglichen.

Figure 00000001
Method and device for more effectively controlling a stack of paper in a reproduction device. The height control behavior of the paper stack is parameterized, with additional lifting commands being issued if it is determined that such increments are required. The height control behavior is parameterized by sampling data during a sampling period, including increments that are initiated by switches. During parameterization, additional increments are initiated by a source that differs from that for the increments initiated by switches in order to enable more effective control of the paper stack.
