PCT No. PCT/DE95/00490 Sec. 371 Date Oct. 22, 1996 Sec. 102(e) Date Oct. 22, 1996 PCT Filed Apr. 10, 1995 PCT Pub. No. WO95/29430 PCT Pub. Date Nov. 2, 1995In 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.
