  • high performance electrographic printing with printing speeds of more than 40 pages per minute mainly so-called punched paper is used.
  • This Paper has lateral holes on its longitudinal edges for transport and for position monitoring of the paper. It will be there driven by caterpillars in the side transport holes intervention. Often this paper also has cross perforations, along which the individual sides of each other be separated.
  • the edge perforation is used in particular when processing pre-printed paper.

Then the record carrier web from a transport motor with a first, relatively low speed along a direction of transport transported by a predetermined length. there a sensor scans a predetermined area of the paper and sends scanning signals to an evaluation device. This evaluates the signals and checks whether they match a given one Brand are assignable. The one between two successive ones The length of the transport is then marked by the evaluation device identified as a value for a side length. Finally, the printing process with a second, relative high transport speed initiated and with the identified Side length value controlled.

If paper 5 with Edge perforation is used, the edge holes are made by the pinwheel sensor 85 continuously sampled and the scanning signals used for anti-slip control. If paper 5 without Perforated edge is used, then the marking 109 is made page by page scanned and this scanning result for anti-slip control used. This side-by-side scanning can instead of or in addition to scanning the pinwheel sensor 85 can also be used with perforated paper 5.
