摘要:
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).

摘要:
An apparatus and method for powering opposing corona chargers for discharging moving receiver sheets. The discharging capacity of the chargers is expanded by adding a high voltage DC offset to a current regulated, AC voltage limited power supply.
摘要:
An objet of the invention is to electrostatically discharge a printing material, to which a toner has been applied, in an appropriate manner. In accordance with the present invention, a method for electrically discharging toner-coated printing material, in particular for an electrophotographic printing machine, is provided, in which case certain areas of the printing material are electrically discharged. Furthermore, a discharge device for a printing machine, specifically for an electrophotographic printing machine, is provided for electrically discharging toner-coated printing material, said device using a control device for electrically discharging certain areas of the printing material.

摘要:
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.
