Abstract: An exposure device includes plural light-emitting elements, a light amount detection unit, a controller, plural holding units and a connection unit. The controller sequentially determines control values of the light-emitting elements based on comparison between the light amounts detected by the light amount detection unit and a predetermined reference value. The holding units are provided for the light-emitting elements, respectively. Each holding unit holds a control voltage of the controller. When the controller is to sequentially determine control values of a part of the plurality of light-emitting elements, the connection units connects the controller and the holding units corresponding to one or more light-emitting elements for which control values are determined earliest among the part of the plural light-emitting elements, before the controller determines the control values of the one or more light-emitting elements.

Abstract: The banner or cover sheet for a print job may be used for aperiodic sampling of transfer performance and/or fusing performance. Sensing pre-process and post-process is required. The resulting sampling is aperiodic and dependent on the job flow. In office products there is typically a frequent generation of cover sheets and the information collected in this way can be useful in system performance optimization. The concept is described for a tandem transfer system.
