Covering and cleaning device for ink jet print-head - recycles dried ink from nozzle plate through filter and pump to source via magnetically operated valve

A three-way valve (2) delivers ink from a reservoir (1) to the printhead (4), whose nozzle plate (4a) is capped (5) with a hermetically sealed space (5a) connected to an ink return container (6). Max. and min. level detectors (6b, 6c) are wired to the controller (8) of the valve (2) and pump (3). Wh...

Zusammenfassung:A three-way valve (2) delivers ink from a reservoir (1) to the printhead (4), whose nozzle plate (4a) is capped (5) with a hermetically sealed space (5a) connected to an ink return container (6). Max. and min. level detectors (6b, 6c) are wired to the controller (8) of the valve (2) and pump (3). When the head (4) is rinsed, dried ink flushed into the container (6) is recycled by suction (6a) through a filter (7), to proceed via the valve (2) back to the reservoir (1). USE/ADVANTAGE - For marking identity of originals in microfilm cameras. Fully automatic, reliable and cost-saving device recycles accumulated ink without ventilation.
