摘要:
A networked or other shared users electronic printing system for printing plural print jobs of plural printed sheets of the different users, includes a printer mailbox system (10) having a sheet distribution system (16) for automatically directing and stacking the print jobs into different individual mailbox bins (11). The mailbox bins (11) are electronically assigned to different respective users. A bin almost-full sensing system (12) detects and signals that the stacking level of the printed sheets in the bin has reached a preset almost-full level (12b) which is less than the preset limited sheet full stacking capacity (32) of the bin. A connecting mailbox control system may indicate to that user at that user's remote terminal that only a preset limited further number of printed sheets may be directed to that same bin upon the actuation of the bin almost-full sensing system. The control system may provide several user options, and/or automatically control the mailbox sheet distribution system to direct subsequent print jobs or a split portion of a print job to a different mailbox bin, or to a higher sheet stacking capacity overflow bin (11a).

An agglomerate removal device for removing unwanted particles from images on a photoreceptor (10) includes vacuum pick off source (81) and baffles (84,85) that create a controlled aerodynamic drag under the photoreceptor before the images reach a transfer station. Removing the agglomerates improves the quality of images transferred at the transfer station to receiving substrates.

摘要:
A sheet stacking and lifting cassette tray assembly for reliably and effectively feeding sheets of different basis weight for use in a reproduction machine. The sheet stacking and lifting cassette tray assembly includes a cassette frame (300) including a frame floor (302), and frame side walls (304,306); a plurality (310) of sheet stacking and lifting subassemblies mounted within, and to, the frame side walls for applying selectable values of sheet lifting normal forces against a sheet feedhead. Each sheet stacking and lifting subassembly of the plurality of sheet stacking and lifting subassemblies includes a pivotable stacking and supporting plate (320,330), and a set of springs (322,324,332,334) having a spring rate for providing a normal force having a particular value for lifting a stack of sheets. The sheet stacking and lifting cassette tray assembly also includes a selecting device (104) for engaging a first number of the plurality of sheet stacking and lifting subassemblies so as to prevent the first number of the plurality of sheet stacking and lifting subassemblies from applying a normal force for lifting, thus varying a number of the sheet stacking and lifting subassemblies applying a normal force to a stack of sheets of a given basis weight, and thereby enabling reliable and effective feeding of sheets from such stack without sheet feeding miscues.
