Abstract
In franking machines (1), the printing head (2) of a printing mechanism (3) is susceptible to interference by dust particles, which are introduced by the transport of the objects to be mailed such as letters, postcards, and printed matter and by the objects themselves. It is therefore proposed that a suction air or compressed air device (9) be installed in the franking machine (1) at least in the area near the printing head (2) to protect it from dust-like foreign materials, etc.
