A printer or copier has a toner transfer belt which is moved into an out of engagement with a transfer printing area. The toner transfer belt is carried on an arrangement of rollers that maintain a constant tension on the toner transfer belt. Rigid linking levers extend between the rollers of the roller arrangement so that belt tension is maintained by movement of compensation rollers, outward while moving a transfer roller upward, for example.

A system and method are provided for coating a container for acceptance of consumables. An information carrier is provided on the container for the first memory area in which a container-individual identifier number is non-erasably stored, and an erasable second memory area is provided of the information carrier providing consumable-specific data.

Printer or copier system having re-employable container for consumables and method for the employment of the container

In a method for improving the printing quality for electrographic color printing, print consumables, particularly toner, are monitored in container-exact fashion and substance-specific information are employed for the control of the printing process. Toner expiration dates for the consumables are identified and noted early at the respective printing location. The consumable contained in the container and the amount of consumable contained is thus stored in machine-readable fashion at the container. An information carrier is provided at the container for non-contacting transmission of data and energy from a data read and/or write station to the container. A transponder that is provided with an individual hardware identifier is provided as the information carrier. The hardware identifier may be employed as a component part of codes for device control. The printer or copier system disclosed includes a recycling concept for consumables containers. One and the same container is multiply employed, and the current container content can be acquired container-individually at any time by machine. The containers are provided with the information carrier that contains the machine-readably encoded information about the current or more recently contained consumable situated in the container. A module that can be electronically written and read in non-contacting fashion is employed as the information carrier, particularly the transponder. The data stored in the transponder can be supplied to other system components such as a filling station, a central computer with a data bank, and the printer or copier devices.

The apparatus for conveying finely powdered material from a reservoir includes a suction/pressure unit that projects into the reservoir. A gas is introduced into the suction/pressure unit and is mixed with the finely powdered material that is sucked into suction/pressure unit from the reservoir to form a powder/gas mixture and this mixture is discharged. Compressed air blows into the reservoir in a finely dispersed manner to fluidized the finely powdered material so that the extraction of the finely powdered material from the reservoir is facilitated.

Apparatus for conveying toner material from a reservoir

A method for operation of a printing mechanism in an electrographic printer or copier, whereby a charge image is applied at a surface region of a toner image carrier. The surface region provided with the charge image is conveyed past at the transfer surface of a transfer element at a spacing of a developing gap. The actual width of the gap is controlled with a loop control circuit.
