METHOD AND DEVICE FOR PAGE BY PAGE CONVEYANCE OF A PRE-PRINTED STRIPLIKE RECORDING MEDIUM IN A PRINTER

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 th e same optical marking (109) on all pages. In a start operation, the front edge (110) of th e 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 specifi c 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 (10 0) as a page length value. The printing process is initiated at a second relatively high speed o f conveyance and conveyance is controlled according to the identified page length value.
