摘要： The invention relates to a method and a device to control a paper drive-mechanism (8) which is devoid of a sprocket feed in an electrographic printer that outputs data on a pre-printed striplike recording medium (5). Said recording medium (5) has the same optical marking (109) on all pages. In a start operation, the front edge (110) of the recording medium (5) is inputted into an input zone (69) at a specific insert mark (65a), whereupon said recording medium (5) is conveyed by means of a conveyor motor (41, 102) in direction (A) at a given length and at a first relatively low speed. A sensor (59,85) scans a specific area of the recording medium (5) during the conveyance process and transmits scanning signals to an evaluation device (100). The evaluation device (100) examines whether the scanning signals coincide with the marking characteristics (109) and the length of conveyance between two similar successive markings (109) is identified by the evaluation device (100) as a page length value. The printing process is initiated at a second relatively high speed of conveyance and conveyance is controlled according to the identified page length value.

摘要： The invention concerns an electrographic printer with an intermediate medium (32) for simultaneously printing a first web section (A) of an endless medium and a second web section (B) arranged next to and at a distance from the first web section (A). Both web sections are drawn along a path past the intermediate medium (32) by a transport system (66, 68, 70, 72). During the printing process, a tensioning device (34) bias the first and second web sections (A, B) against the intermediate medium (32), a web-tensioning unit located behind (relative to the direction of transport) the transport device (66, 68, 70, 72) applies a traction force to the web sections (A, B) in the direction of travel. In addition, a first equalisation device (56) and a second equalisation device (58) separated from the first are provided between the transport device (66, 68, 70, 72) and tensioning device (34). The equalisation devices bias the first or second web section, as appropriate, against the direction of transport during the printing process.

摘要： In a printing system, a recording medium (5) is firstly printed by a first printer (10/1) and is then printed by a second printer (10/2). The print data is supplied in a page by page manner to the first and second printers (10/1, 10/2) from a print data source (11). Using the respective print data, page information data is transmitted to the printers (10/1, 10/2), and corresponding page information is filed in a buffer storage (22) from the first printer (10/1). In addition, both the page information data transmitted to the second printer (10/2) from the print data source (11) and the page information stored in the buffer storage (22) are verified in a page by page manner whether they correspond to a predetermined rule. For positionally accurate printing, the first printer prints a synchronization mark on the recording medium which is read in the second printer and which is used to control the printing process there.

摘要： The invention relates to a transfer printing station for an electrographic printing or copying device. Between two transfer printing jaws (18, 20), the transfer printing station comprises at least one contact pressure element in the form of a pad-roller (26) or a form guide rail (36) with a supporting roller (28). The contact pressure element (26, 36) presses the recording carrier (12) against the surface of the photoconductive drum (10), whereby the supporting roller (28) which supports itself on the edges of the photoconductive drum (10) prevents a minimum distance from falling short.
