  • Patent number: 5963770
    Abstract: A printing system including three print engines. One of the print engines is non-operational while the other two print engines are operational. The non-operational print engine is redundant and only actuated in the event that one of the operational print engines develops a malfunction causing it to be non-operational. At that time, the previously non-operational print engine becomes operational. In this way, two print engines are continually in operation with one print engine being non-operational. This printing system significantly improves reliability and minimizes maintenance requirements.
