Abstract
The telecopier receiver has a motor driven paper support cylinder. A circuit controls the normal and slip speeds of the motor. A writing element mounted near to the cylinder writes on the paper as a function of a telephotographic signal except when it finds itself between two marks on the cylinder and at the edge of the paper, which periodically define a dead sector. Telephotographic receiver circuits gets a signal which actuates a preliminary preparation phase and an effective copy phase. An electronic control circuit is connected to a cylinder position detector of the telecopier-receiver so as to periodically furnish a local dead sector logic signal. The relative speed difference between the cylinder motors speed is equal to the ratio between a second timing frequency and a first timing frequency.
