  • Patent number: 5752697
    Abstract: In a shared users printing and mailboxing system, with a shared remote printer with an operatively connecting array of lockable mailboxes, in which system electronic print jobs from different users at different locations may be electronically sent to be printed, which hardcopy print jobs are automatically fed into respective selected lockable mailboxes, wherein the printer has an internal paper path for this printing with sheet jam clearance capability and a system for signaling a sheet jam, and at least one openable printer access door providing access to the paper path for jam clearances; a print job security improvement system with an automatic locking system for electronically locking the printer access door and an access door on the mailboxing system during printing of security sensitive print jobs to prevent access to the internal printer paper path, but automatically unlocking the printer access door after the hardcopies have reached the selected mailboxes if there is no sheet jam signal, and maintaini

  • Patent number: 4925171
    Abstract: In a sorter for sorting sheets fed from a sequential source of sheets, with a closely vertically spaced array of sorter bins, and apparatus to vertically move the array of sorter bins relative to the source of sheets for sequentially loading individual sheets into individual sorter bins, the improvement including partially horizontally displacing one individual sorter bin at a time from the superposed array, in coordination with the vertical movement, towards the source of sheets to provide an enlarged bin entry opening without requiring any change in the vertical spacing between the bins, and subsequently horizontally moving a bin so displaced back into vertically superposed alignment with the other bins of the array. Also disclosed is stapling sheets sorted into the bins, wherein the same system for partially horizontally displacing the sorter bins also functions to move one displaced bin at a time into the stapler for stapling the sheets sorted in that bin without removal therefrom.

  • Patent number: 4299478
    Abstract: An arrangement is disclosed for combining the capability for bound document copying with a document handling apparatus in a reproduction machine. To this end, an arrangement is devised wherein the document handling apparatus is contained within a frame which contains a light-tight cover for bound documents having three-dimensional shape. The arrangement includes a pivoting connection between the document handling apparatus and the frame relative to the platen of the reproduction machine and between each other so as to permit access to the platen for manual document placement and bound document copying.

  • Patent number: 4033294
    Abstract: A magnetic brush developing apparatus having magnetic rollers with end sleeves formed of an insulating material. A trimming bar is provided having a concave portion below a leading edge thereof to facilitate the return to the sump zone of excess developing material. Magnets disposed within the rollers are mounted on channel members in a manner to direct the magnetic forces about each brush to ensure blanket coverage and a downstream configuration to direct developing material over a baffle associated with a cross-mixing baffle assembly. A screen is provided within the housing of the assembly to collect foreign objects. A mixing and transport device is positioned within the sump zone and is comprised of a plurality of spaced-apart augurs disposed on a shaft and a plurality of radially-extending bars affixed to the ends of the augurs.

  • Patent number: 3949704
    Abstract: A magnetic brush developing apparatus as disclosed having magnetic rollers with end sleeves formed of an insulating material. A trimming bar is provided having a concave portion below a leading edge thereof to facilitate the return to the sump zone of excess developing material and having a flat surface forming a converging passageway with a said roller whereby to compress developing material transported on said roller. Magnets disposed within the rollers are mounted on channel members in a manner to direct the magnetic forces about each brush to ensure blanket coverage and a downstream configuration to direct developing material over a baffle associated with a cross-mixing baffle assembly. A screen is provided within the housing of the assembly to collect foreign objects.
