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.

Method for automatically identifying a type of transparent conveyor belt

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

Treating transport mechanism in a printing press

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. The device uses a control device for electrically discharging certain areas of the printing material.

Method and device electrically discharging a printing material

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.
