Ink printing head protection device for protecting ink printing heads from drying out seals spray nozzles hermetically during pauses in printing by active moistening with a solvent in a vapor phase

摘要

Three color cartridges (K1-K3) for print heads (DRK) fit on a moistening device. Sealing lips (DK) can be O-rings/soft rubber parts. Friction force during insertion of the print head on the seals must not be too great. The print heads are hermetically sealed and kept in a vapor atmosphere with a heated felt/fabric mat (Fz) soaked with a solvent.
