Abstract (en)

An image reproduction device including a print processing system and a print sheet conveying system, adapted to convey the sheets with a continuously variable and dynamically adjustable processing speed. The device is adapted to lower the processing speed when the mains connection cannot deliver sufficient power to run at nominal processing speed and is therefore provided with a current monitor unit (41) for monitoring total electrical current drawn by the device from the mains connection (40) and a control unit (12) connected to the current monitor unit (41) and arranged for dynamically adjusting the processing speed to a lower value when the total electrical current is above a preset maximum value (I max ). The control unit regulates the lower processing speed value so as to obtain that the total electrical current drawn by the device from the mains connection is kept substantially equal to the preset maximum current value (I max ) until the mains power is again sufficient for running at nominal processing speed.
