Abstract
A franking machine is disclosed in which the franking impression is printed by means of an ink jet print head. Debris from mail items which is liable to be deposited on the nozzles of the print head is removed periodically by a cleaning device operated in gaps between feeding of successive mail items. In the event that a gap does not occur, the feeding means is controlled periodically to cause occurrence of a gap. The ink jet print head may utilize solid ink which is heated to melt it for ejection in drops from the nozzles.
