Abstract
A paper-handling and maintenance station assembly for use in an ink jet printer is described. A paper-handling loop is included in a paper conveying system. The loop has at least one opening therein. A rotatable maintenance station has a plurality of members positioned about the circumference thereof, each member performing a different maintenance function. The maintenance station can be provided within an area enclosed by the loop and can be moved in an axial direction to engage a printhead which can be fixedly positioned at a location exterior to the loop enclosed area. The opening in the loop allows the engagement between the maintenance station and printhead.
Claims20
A paper handling and maintenance station assembly for use with an ink jet printhead, said assembly comprising:
- a paper-conveying means including a paper-handling loop, said loop defining an area substantially enclosed by said loop;
- a maintenance station movably positioned within said area enclosed by said loop, said maintenance station including at least two members selected from a printhead priming station, a capping-spitting station, a nozzle wiping blade and a sliding single-jet priming station, each member being positioned about a circumference of said maintenance station;
- and
- at least one opening in said loop, said opening providing periodic access by said maintenance station to a printhead adapted to be positioned exterior to said loop-enclosed area.
An ink jet printer for printing on a recording medium comprising:
- paper-conveying means including a paper-handling loop;
- a full-width ink jet printhead;
- a printer assembly support means fixing said paper-handling loop and said printhead in close proximity to one another;
- said loop defining an area substantially enclosed by said loop;
- a maintenance station connected to said printer assembly support means, said maintenance station being movably positioned within said loop-enclosed area, said maintenance station including at least two members selected from a printhead priming station, a capping-spitting station, a nozzle wiping blade and a sliding single-jet primary station, each member being positioned about a circumference of said maintenance station;
- and
- at least one opening in said loop, said opening providing periodic access by said maintenance station to the printhead, said printhead being positioned exterior to the loop-enclosed area.
An ink jet printer for printing on a paper medium comprising:
- a paper-conveying means including a paper-handling loop;
- an ink jet printhead;
- a printer assembly support means positioning said ink jet printhead close to said paper-handling loop;
- a maintenance station rotatably mounted on said printer assembly support means;
- said maintenance station including at least two members selected from a printhead priming station, a capping-spitting station, a nozzle wiping blade and a sliding single-jet priming station, each member positioned about a circumference of said maintenance station;
- at least one of said printhead and said maintenance station being movably positioned with respect to the other of said printhead and said maintenance station, said movement providing contact between said printhead and said maintenance station;
- and
- rotation of said maintenance station presenting a selected one of said members to said printhead.
