Abstract

The objective is to reduce the downtime of a printing system in the printing industry. Provision is therefore made to supply the drive regulators (3) of a printing system (1) simultaneously with a plurality of clock signals. Each of the drive regulators (3) independently selects one of the clock signals for synchronization. In the event of failure of a signal source, the printing system is not interrupted but the drive regulators (3) switch automatically to the clock still present.
