Abstract: In the electrophotographic apparatus for printing one or more copies of a document, a photoconductive drum rotates at a constant velocity while being charged; a document feeding device advances a document through a light exposure portion at a constant speed and, an optical device projects an image of the exposed document onto the drum to form an electrostatic charge latent image thereon. A latent image is developed to form a toner image after which the toner image is transferred onto a record paper and the toner image is fixed on the record paper to form a final copy. Clock pulses in synchronism with the rotation of the photosensitive drum are produced, whereby master and slave timing pulse generators receive the clock pulses to produce timing pulses. Then a control device receives the timing pulses and produces control signals necessary to control the operation of the apparatus.

Abstract: A method and a device for controlling operating processes applied to particles. The device comprises a number of operating stations, such as, lifting- and sluing conveyors to allow for feeding the particles to an indexing rotary plate and conveying of particles to a processing stage, e.g. a welding device. The operating processes of the operating stations are initiated according to a common, pre-set cycle, at least one of the operating stations is associated with a correcting process initiated by a sensor arrangement for detecting faults in the operating process, for shortening the outages and for increasing the total output. The operating process involving a fault detected by the sensor arrangement is immediately interrupted, whereupon the correcting process is initiated independently of the common, pre-set cycle. The common, pre-set cycle serves to initiate dependent subsequent or previous operating processes of the operating stations until the end of the correcting process.
