In principle, it is possible to use any Texts, code and special characters in the franking stamp printing area and a any or an advertising cliché assigned to a cost center to press.
  • a franking machine for example T1000 from the applicant Francotyp-Postalia AG & Co., is controlled by a microprocessor controlled, which is surrounded by a secured housing, which has an opening for feeding a letter. With every letter feed transmits a mechanical letter sensor (microswitch) Print request signal to the microprocessor, which is a print image generated and after a settlement of the postage to be franked triggers a print.
  • the franking imprint contains one before entered and stored postal information for transportation of the letter.
  • a printing device for an ink jet franking machine has already been described in US Pat. No. 5,467,709 proposed, being on a piece of mail at a approximately horizontal letter transport a franking imprint using a Inkjet printhead is printed.

  • the arrangement can do not avoid skewing of the print media.
  • This transport and printing device is located in the base and is controlled by a meter.
  • a trigger sensor for the printing process is located in the base for letter recognition, just in front of the inkjet printhead recess and interacts with an incremental encoder on the drive of the conveyor belt. With a transmitted light barrier as a trigger sensor (EP 901 108 A2), the front edge of particularly thick mail items is clearly recognized.
  • optical sensors for mail item jam detection are used in the base of the JetMail®. Upstream of the JetMail® franking machine, an automatic feed and a dynamic scale are arranged in the Condord® franking system, which enables real mixed mail processing for mail items of very different formats, thicknesses and weights.

  • the compact device in which the nozzles of the ink jet print heads are arranged so close to the edge 511 of the transport drum 51 that practically no distortions can occur in the printed image, is of course advantageous. Another advantage is that the transport drum can be manufactured with great precision, which results in a uniform transport of the print carriers under the ink jet print heads.
  • a main circuit board (not shown) for the control controls the printing device.
  • markings are applied close to the circumference, which are distributed over the circumference of the transport drum 51.
  • the markings are, for example, reflective lines which are detected by a reflex light barrier of an encoder 52 and are converted into pressure pulses in a ratio of 1: 1 by the microprocessor of the above-mentioned control system. Fluctuations in the transport speed therefore have no influence on a printed image.
  • the encoder 52 can be arranged on the motor axis 131.
