Abstract
A hardcopy apparatus including a main roller and a loading mechanism to load a medium into the hardcopy apparatus, said loading mechanism including a vacuum holddown input unit to hold media down onto a surface of said holddown unit. In addition, a method of loading a medium into a hardcopy apparatus including a vacuum holddown unit, a driving roller and a secondary roller, comprises the steps of: manually positioning the medium onto a surface of the holddown unit; by rotating the secondary roller, advancing the medium towards the main roller; and engaging the medium to the main roller.
Claims18
A hardcopy apparatus comprising:
- a main roller;
- and
- a loading mechanism to load a medium into said hardcopy apparatus, said loading mechanism comprising:
- a vacuum holddown input unit to hold media down onto a non moving surface of said holddown unit comprising;
- a vacuum source, connected to atmosphere through a plurality of first apertures formed into said surface;
- and
- a vacuum channel to generate a negative pressure capable of holding down said media onto the surface, while loading said medium,
- wherein said surface comprises a plurality of recesses.
A method of loading a medium into a hardcopy apparatus including a holddown unit provided with a vacuum source, a main driving roller and a secondary roller, comprising:
- manually positioning only a portion of said medium onto a surface of the holddown unit while said medium is stably held;
- releasing said medium when correctly positioned on said surface;
- by rotating the secondary roller, advancing the medium towards the main roller;
- and
- engaging the medium to the main roller.
A hardcopy apparatus comprising:
- a main roller;
- and
- a loading mechanism to load a medium into said hardcopy apparatus, said loading mechanism comprising:
- a vacuum holddown input unit to hold media down onto a surface of said holddown unit comprising;
- a vacuum source, connected to atmosphere through a plurality of first apertures formed into said surface;
- a vacuum channel to generate a negative pressure capable of holding down said media onto the surface, while loading said medium;
- and
- a secondary roller, wherein said negative pressure causes a back side of said medium to engage said secondary roller and transfer said medium to said main roller;
- wherein said surface comprises a plurality of recesses.
