Abstract:
COVER APPARATUS FOR USE WITH A SHEET STACKING UNIT IN WHICH THE COVER OF THE UNIT IS CONNECTED TO THE FRAME BY ONE OR MORE RODS WHICH ACT AGAINST TWO DIFFERENT SPRINGS. ONE SPRING IS RELATIVELY STIFF TO URGE THE COVER TO A SLIGHTLY OPENED POSITION WHEN THE COVER IS UNLOCKED THE OTHER SPRING IS RELATIVELY COMPRESSIBLE TO ACT AGAINST THE ROD WHEN THE COVER IS RAISED TO ITS FULLY OPENED POSITION. CIRCUITRY IS COUPLED TO THE COVER LOCKING DEVICE IN EFFECT A POP OPEN ACTION WHEN A SIGNAL IS RECEIVED TO UNLOCK AND ALSO TO A TRAY BELOW THE COVER TO RAISE THE TRAY WHEN THE COVER IS FULLY EXTENDED.
Abstract:
An apparatus for raising developer from a sump to an elevated position over an electrostatic plate bearing a latent image and cascading the developer over the plate to develop the image including a rotating frame having scoops fastened thereto which are filled with developer as they pass through the sump and empty the developer onto a guide member located at the elevated position which directs the developer over the plate. The scoops are independently mounted for rotation on the frame so that each can be orientated to its optimum position for emptying developer therein when at the elevated position.
Abstract:
A method and apparatus for providing duplex copies in pre-collated output copy sets from a set of documents recirculated in order by first copying only the even-ordered documents in the set once onto the first sides of substrates and transporting those copies to a buffers then making individual copies in order of all the documents by alternately copying odd order documents on the reverse side of copies fed from the buffer while alternately copying even ordered documents onto copy substrates fed from a different copy substrate source and transporting the copies made from the buffer to an output tray to create pre-collated sets while simultaneously transporting the copies from the other copy substrate source to the buffer to replace the copies fed therefrom; repeatedly individually copying all of the documents in the set in the latter manner by a number of document recirculations equal to one less than the total number of copy sets desired, and then, for a last copy set, making copies of only the odd ordered documents onto the reverse side of copies fed only from the buffer.
