摘要

The capping device of a cassette comprising a capping device and a cleaning device for the capping and cleaning, respectively, of the jet nozzle surface (8) of a printing head (3) of an ink jet printer comprises a drivable capping cushion (14) having an endless surface (13) and the cleaning device comprises a drivable cleaning tape (17). The capping device and the cleaning device are accessible in a capping position (10) and a cleaning position (12) through a window (9, 11, respectively) in a cassette wall (7). For the driving of the cleaning tape, the cassette comprises two rollers (18, 19) which cooperate at their circumference and wherebetween the cleaning tape (17) passes. One of these rollers (18) can be coupled to a drive device of the ink jet printer. The cleaning tape coming from the feed reel first passes a part of the surface of the capping cushion and via the cleaning position to the two rollers whereby the tape is fed to a storage space (20) formed in the cassette.
