Abstract: A decoder configured to decode residual levels, and sequentially dequantize the residual levels by selecting a quantizer out of a set of default quantizers depending on a current transition state, and updating the current transition state depending on a current residual level's characteristic obtained by an application of a binary function onto the current residual level, and depending on a quantization mode information contained in the data stream. The current transition state transitions, according to a surjective mapping which depends on the quantization mode information, from a domain of combinations of a set of one or more transition states with the current residual level's characteristic onto the set of one or more transition states, wherein a cardinality of the set of one or more transition states differs depending on the quantization mode information.

Abstract: In a method for automatically identifying a conveyor belt in a printer as being one of a plurality of belt types, the conveyor belt is moved along a circulatory path. A start and an end of a longitudinal marking on the moving conveyor belt are detected. A distance of travel of the moving conveyor belt between the detecting of the start and the end is sensed to provide a sensed marking length. The sensed marking length is allocated to a nearest of a plurality of nominal marking lengths. Each nominal marking length is associated with a respective one of said belt types. The belt type is associated with or defined by a set of one or more printer control parameters.

Abstract: Treating a transport mechanism (5) for transporting print material (2) in a printing press (1) that uses toner in which oil-bearing substances (27) adhere to the transport mechanism (5). A cleaning device (30) is provided with at least one cleaning element (33) movable relative to the surface of the transport mechanism (5) for application of at least one oil-repelling substance (37) that reduces the adherence of the oil-bearing substances (27) to the transport mechanism (5). Accordingly, this cleaning element (33) can strip the surface of the transport mechanism (5) of oil-bearing substances (27).

Abstract: A method and a device to electrostatically discharge a printing material, to which a toner has been applied, in an appropriate manner. The method is provided for electrically discharging certain areas of a toner-coated printing material, in particular for an electrophotographic printing machine. The discharge device is provided for a printing machine, specifically for an electrophotographic printing machine, for electrically discharging toner-coated printing material.

Abstract: Recognizing a print substrate in the vicinity of a sensor within a printing machine, whereby a change in the capacitance of the system formed by the sensor and a surface of an area in which a print substrate should be recognized, is recognized by the sensor. In this way, print substrates can already be identified on the basis of a dielectric constant that is different from that of air.
