In a method and system for printing, individual pages of a print medium are transported. With a printing unit, a side of the respective individual page facing it is printed and the applied toner image is fixed. With an inverter, the individual pages with the fixed toner image are inverted after the first printing event and resupplied to the printing unit for printing on an other side. The printing unit has first and second printing groups respectively comprising first and second exposure units, first and second charge corona devices, and first and second developer stations. Individual pages are supplied in succession to both of the first and second printing groups, and the printing groups respectively print two varicolored print images on the same side of the same individual page. A first latent image charge inked by the first developer station with toner of a first color is generated in each of the first and second printing units given a circulation of the intermediate carrier with aid of the first charge corona device and the first exposure unit. The second charge corona device and the second exposure unit subsequently generate a second latent charge image superimposed on the inked first latent charge image. The second charge image is inked by the second developer station with a toner of a second color.

A printer or copier includes a high speed monochrome or two color printer portion and a slower full color printer portion. Print job signals are divided into monochrome and color printed pages and sent to the corresponding printer portion. The printers, or a paper handling path between the printers, is controlled to assemble the printed pages into a predetermined sequence order.

Printing system and printing method for producing a mixed color sheet sequence

A printer or copier and method generates toner images for transfer onto a recording medium. A latent charge image is generated on a photoconductor and is developed by the application of toner by at least one developer station to generate the toner image for transfer to the recording medium. A plurality of the developer stations are provided along the photoconductor to develop the images in color using a color separation method. A transfer band collects the color separations on top of one another to generate the overall toner image which is transferred to the recording medium. Multiple modules, each with developer stations, a photoconductor and a transfer band may be provided for one sided or two sided printing.

Multi-functional printer device for printing tape-shaped recording media

An electrographic printer device is designed for printing web-shaped recording media (10) having different web widths in different operating modes, such as single-colored and multi-colored simplex printing, single-colored and multi-colored duplex printing and for simultaneously printing two recording medium webs in parallel operation. To this end, the units of the printer device such as intermediate carrier (11), transfer printing station (15) and fixing station (18) comprise a usable width of at least twice the web width of a narrow recording medium. The printer device further contains a deflection means (28) following the fixing station (18) and engageable as needed and having an allocated return channel to the transfer printing station (15) via which the recording medium (10) is turned and resupplied to the transfer printing station (15) in single-color or multi-color duplex mode.

A tank system for cold fixing a toner powder on a paper as it is conducted through a fixing station of a non-mechanical high speed printing and copying device characterized by the printed paper being conducted through an atmosphere enriched with the vapor of a fixing agent. The tank system includes an injection tank which is connected to a replaceable feed container containing the agent with the injection tank being controlled to inject the agent into the fixing station to maintain the desired concentration of the vapor. The system also includes a recovery device including a water separator which separates condensed fixing agent from the water of the condensate. The system also includes a buffer tank which receives the recovered fixing agent, a pressure tank which is coupled to the buffer tank and has an outlet with a valve connected to the supply system, and an air pump to supply compressed air to the pressure tank to return any agent in the tank into the feed container and/or into the injection tank.
