Abstract
Wide format multiple ROB assembly. Raster Output Bar assembly comprises one or more individual image bars mounted onto their own sub-assemblies. Wide format ROB is assembled at the factory onto a datum structure from individual sub-assemblies staggered to achieve a desired wide format. The sub-assemblies are adjustably positioned on the datum structure based on the datums obtained off of the individual image bars. No further in-machine adjustments are needed in the field.
Claims20
A method of setting up an image bar for recording images in a scanner comprising:
- providing a datum structure having a first set of adjustable datum openings;
- selecting at least one mounting bracket having a second set of datum openings and a third set of datum openings;
- selecting at least one image bar having a fourth set of datum openings;
- aligning said fourth set of datum openings of said image bar with said third set of datum openings of said mounting bracket;
- mounting and holding said image bar on said mounting bracket by inserting a first set of datum pins through said aligned fourth set of datum openings and third set of datum openings;
- aligning said second set of datum openings with said first set of adjustable datum openings on said datum structure;
- mounting and holding said mounting bracket on said datum structure by inserting a second set of datum pins through said aligned second set of datum openings on said mounting bracket and through said first set of adjustable datum openings on said datum structure;
- and
- positioning said image bar on said datum structure by slidably moving said second set of pins of said bracket in said first set of adjustable datum openings on said datum structure until end-to-end pixel stitching adjustment is achieved among one or more image bars covering the whole length of an electrophotographic photoreceptor.
