Abstract:
1. A process for supplying substrates for one-sided or two-sided printing in an electrophotographically operated digital printing apparatus, in which substrates are fed from at least one supply unit to a conveyor and transferred, in the course of the conveyor operation sequence, onto a belt that runs through a printing unit of the digital printing apparatus, the process comprising: selecting successive points in time for acceleration of substrates from said at least one supply unit for supplying substrates, with the least possible space between successive substrates, depending on the type of print stock of such substrates, wherein the arrival time of at least one substrate at a particular place on the belt is detected by a sensor and designated through a signal from the sensor, and by this arrival time for this detected substrate, the point in time for a successive substrate is selected for supplying such successive substrate, that is still in the same supply unit from which the detected substrate originates, from this supply unit to the belt.
