Abstract
A media guidance system for substantially reducing media jamming as the leading (head) end of a web of recording media is directed over the drum surface of an internal drum type laser imagesetter during a media loading procedure. The media guidance system includes a hollow shield, at least one outrigger extending laterally away from the hollow shield, and at least one retractable plate assembly for selectively applying a pressure load against the leading end of the recording media as it approaches the exit aperture of the internal drum.
Claims10
An apparatus comprising:
- a media support surface,
- a media loading system for directing a supply of recording media onto the media support surface during a media loading procedure, the media support surface including an exit aperture toward which a leading end of the recording media is directed by said media loading system during the media loading procedure;
- a system for forcing the leading end of the recording media against the media support surface at the exit aperture;
- a guiding system for guiding the recording media against the media support surface during the media loading procedure;
- and
- at least one outrigger extending transversely away from the guiding system.
A media guidance system for a scanning system, the scanning system including a drum for supporting a supply of recording media, a media transport system for displacing the recording media onto the drum toward an exit aperture, a scanning laser mechanism for directing a scanning laser beam toward the drum, and a hollow shield for enclosing the scanning laser beam, comprising:
- a system mounted to a distal end section of the hollow shield for directing a first portion of the recording media against the drum;
- at least one outrigger, extending transversely away from the hollow shield, for directing a second portion of the recording media against the drum;
- and
- a system for forcing the leading end of the recording media against the drum at the exit aperture.
An optical scanner comprising:
- a media support surface having an exit aperture;
- a media loading system for directing a supply of recording media onto the media support surface toward the exit aperture during a media loading procedure;
- a system for forcing the leading end of the recording media against the media support surface, the forcing system including at least one plate member, and a system for selectively applying the at least one plate member against the leading end of the recording media;
- and
- a guide assembly for directing the recording media against the media support surface during the media loading procedure, the guide assembly including at least one outrigger, extending transversely away from the guiding assembly, for preventing the recording media from lifting away from the media support surface.
