  • Patent number: 5951005
    Abstract: There is provided document stacking stacker for stacking documents exiting a wide format machine, including a sheet tray having a planar base plate for stacking sheets thereon and a side wall for abutting sheets thereagainst; guides disposed adjacent the tray to direct sheets therein at an angle relative to the plane of the base plate, a feeder associated with the guides to feed sheets through the guides into the tray; a corrugating bar includes an array air corrugaters, the air corrugators are connected to an air plenum, each of the air corrugators have an air discharge ports for discharge of air against incoming bottom surface of sheets in the direction of movement of the sheets to corrugated the sheets as the sheet is feed to the tray.

  • Patent number: 5361124
    Abstract: An improved fuser system especially effective for a large document type of copier is provided. The fusing system is of the heat and pressure type wherein a fuser roll is internally heated by a lamp so that the fuser surface is at a required fusing temperature. When the full width of the roll is used in a particular fusing operation, e.g. 36" wide documents are being copied, the lamp is heated to a maximum temperature. When the document copy is less than 36" and for a center registered system, the ends of the fuser roll would tend to overheat, since the copy media is absorbing heat only in the center portion. According to one aspect of the invention, a control circuit is provided to recognize that the shorter widths of the copy media are being used and to lower the lamp temperature in response thereto to prevent the fuser roll ends from overheating.

  • Patent number: 5212529
    Abstract: A heat and pressure fuser includes a thin web which is wrapped around a portion of a heated fuser roll to form a fusing area. The web contacts the fuser over a relatively short wrap angle to reduce torque required to drive the fuser roll, thereby enabling a higher process speed. Fusing efficiency is maintained by use of a biasing mechanism which increases the pressure applied to the web both the entrance and exit areas of the fuser.
