Abstract
An ink jet apparatus is disclosed which comprises a disposable ink reservoir and pumps for providing priming and purging to the ink jet and for providing subatmospheric pressure in the vicinity of the jet to collect any debris from the orifice of the jet prior to start up of the jet. In a preferred embodiment, both pumps are peristaltic and are powered by single motive means mounted permanently on a facsimile apparatus with which the disposable ink jet apparatus may be used.
Claims11
A facsimile system comprising:
- copy medium support means for supporting a copy medium during scanning;
- scanning head means movable with respect to said support means so as to create a relative scanning motion between said head and said support means;
- a demodulator means for demodulating signals representing dark/light variations in a document;
- an ink jet for ejecting droplets of ink;
- means for generating control signals coupled to said ink jet so as to control the projection of droplets from said ink jet toward said copy medium for reproducing said dark/light variations;
- a disposable ink jet system comprising
- an ink reservoir, said ink jet being mounted on and carried by said reservoir;
- means for priming and purging said ink jet mounted on and carried by said reservoir;
- means coupling said ink jet to said reservoir said ink jet system including said reservoir being supported on said head means and movable with respect to said support means;
- and
- means for permitting mounting and removing of said ink jet system including said reservoir and said ink jet.
