Variable speed printing device with mains overload prevention

An image reproduction device for document processing, the device comprising:

• a mains power connection that draws electrical power from a power net, said net having a current limitation;
• a processing system that applies visible marks on image support material, including a toner fusing system;
• a conveying system that conveys the image support material from an input section to the processing system and from the processing system to an output section, the conveying system being adapted to convey the image support material with a continuously variable and dynamically adjustable processing speed;
• a current monitor unit that monitors a total electrical current drawn by the device from the mains connection;
• a control unit connected to the current monitor unit and arranged to dynamically adjust the processing speed to a lower processing speed value when the total electrical current is above a preset maximum current value, said lower processing speed value being such that the total electrical current drawn by the device from the mains connection is substantially equal to the preset maximum current value.
