Abstract:
Acquisition device with an acquisition transport system driven by a stepping motor for acquisition of documents delivered by an output transport system of an output device, comprising: (a) means for starting the stepping motor under no-load condition with a current value I.sub.Start selected such that the acquisition transport system reaches a rotational speed which is above a known maximum document speed of the output transport system; (b) means for detecting the speed of the acquisition transport system and decreasing motor current as long as the instantaneous speed of the acquisition transport system is greater than said maximum document speed; (c) means for storing the limit value of motor current at which the speed of the acquisition transport system is equal to said maximum document speed; (d) means for reducing the motor current to said stored limit value each time before a document delivered by the output transport system reaches the acquisition transport system; and (e) means for increasing the motor current again when said document has left the output transport system.
