Electrographic recording medium slip prevention system for copier or printer

摘要

The printing substrate (4) is conveyed by friction in the fixing station between two rollers (1, 2). The printing substrate (4) is braked in front of the rollers (1, 2) by a braking device (3) to tension it. A length equalising unit (5) evens out any length differences in the printing substrate (4). The revolution speed of the rollers (1, 2) is controlled dependently upon the deflection of the length equalising unit (5). The deflection time (txy) between the arrival at a deflection point a and a deflection point b is detected and compared with a reference time (tref). The braking force of the braking device (3) is reduced if the reference deflection time (tref) is exceeded.
