  • Method and apparatus for avoiding slip in transporting a recording substrate in a fixing station of an electrographic printer or copier
    Patent number: 5752153
    Abstract: In the fixing station, the recording substrate 4 is transported by friction between two rollers (1, 2). In order to tauten the recording substrate (4), it is braked by a braking device (3) upstream of the rollers (1, 2). A length equalizing element (5) equalizes any length differences occurring in the recording substrate (4). The rotational speed of the rollers (1, 2) is controlled as a function of the deflection of the length equalizing element (5). The deflection time (txy) between reaching a deflection point a and a deflection point b is registered and compared with a desired deflection time (tsp). The braking force of the braking device (3) is reduced if the desired deflection time (tsp) is exceeded.
