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.

A low cost copy output stacker for engineering size copies includes a vertical catch tray molded into front doors of a copier/printer for accepting the lead edge of the copies and allowing the copies to bend over the top of the catch tray in a stacked position under gravity. A manually operated hinged stop is positioned in a down position blocking the path of copy sheets in order to keep them from reaching the bottom of the catch tray for stacking copy sheets size 11' to 24' and positioned in an up position for copy sheet sizes 24' to 48'.

Copy output stacker for engineering size copies

A low cost document stacking apparatus that passively collects and collates engineering size drawing originals after they have been scanned by use of a catch tray which has two bins. One bin is used to catch 'C' and 'D' size documents and the other bin catches 'E' and larger sized documents. A diverter directs documents to either of the two bins depending on the length of document being scanned.

A copy output stacker for a wide format copier/printer holds and stacks a wide range of copy sizes exiting a copier/printer. The copies are stacked conveniently in front of the copier/printer without occupying much space. The stacker includes the use of an inverted 'window shade' assembly with its roller spring mechanism attached on one end of the base of the roll feed/cutter assembly of the copier/printer, while the other end is pulled out and attached at an angle in front of the media supply drawer in order to form a pocket to catch copy sheets exiting the copier/printer.

This invention is a transfer means in a electrographic printing apparatus having a charge retaining member with a relatively high background potential of a first polarity, a transfer corotron having a relatively high potential of a second polarity and providing a transfer region for a transfer of toner to copy sheets, and a pretransfer baffle disposed adjacent to the transfer corotron, the pretransfer baffle being charged to a potential approximately the same as the charged retaining member and having said first polarity, the pretransfer baffle and the charge retaining member forming a gap for the passage of copy sheets to the transfer region, and the copy sheet being in contact with the charge retaining member before reaching the transfer region.
