Uniform entry of media into an alignment nip
摘要:
Alignment nip regulation may be implemented by controlling the approach of media to an alignment nip. Where media is fed from a plurality of sources and from a plurality of approach angles through a common alignment nip, nip entry may be controlled by focusing the media through a diverter or a jog in an existing path to alter the course followed by the media sheets. The diverter may be configured to direct the media sheets to a contact point at or near the alignment nip, such as on a roller that forms the alignment nip. Alternatively, media sheets arriving at the nip from separate conduits may be separately directed to a common contact point near the alignment nip. In either case, one or more sensors may detect the approach of the media sheets at a time when the sheets are a common, predetermined distance away from the alignment nip.
