Abstract: XEROGRAPHIC APPARATUS AND PROCESS WITH BACKSIDE PHOTOCONDUCTOR IMAGING A closed-loop photoconductor belt capable of transmitting light from its inner surface to a photoconductive layer is imaged on the internal surface after charging of the photoconductive layer. A developer transfers toner to the image area on the external surface of the belt, while scavenging residual toner from the belt external surface. The image representing-toner is transferred from the external belt surface to a copy medium at a transfer station. A back-lighting erase lamp and biased AC pretransfer corona improve transfer efficiency and suppress background transfer during the transfer operation, respectively.

Abstract: A copier-printer is employed in conjunction with an optical scanner and associated character recognition logic to transmit information contained in a document over a telephone line or other communication line. The copierprinter is used to make a copy of the document which is stored in the duplex tray. When a buffer memory associated with the communication line is ready to receive further information for transmission, the copy is retrieved from the duplex tray and circulated through the copier-printer to the optical scanner. The scanner provides the information from the copy to the buffer memory in a non-coded format except to the extent that the character recognition logic is able to code some or all of the information. The copy is advanced from the scanner to a mailbox in the form of a limited access compartment at the bottom of the collator for the copier-printer. The copier-printer may be used to receive information transmitted over the communication line by temporarily storing the information in the buffer memory and then printing the information on paper which is routed to and stored in the mailbox. Information provided to the print buffer for printing can be checked for printing accuracy by scanning the resulting printed paper using the optical scanner and comparing the scanned information with the information originally entered in the print buffer.

Abstract: Non-coded and coded information are merged in a copier-printer system by copying the non-coded information onto one or more sheets of paper during a first pass of the sheets of paper through the system and thereafter selecting the sheets of paper with the non-coded information copied thereon from the secondary or duplex paper trays of the system for a second pass through the system during which coded information may be printed on the sheets of paper. Selection of the sheets of paper having non-coded information copied thereon is integrated with sheets of paper from the primary tray which are to contain exclusively coded information. Copying of the non-coded information and printing of the coded information is carried out under the control of mag cards indicating the pages and page locations within a given document where the non-coded information is to be copied and in some cases containing coded information to be integrated with the non-coded information In one method, non-coded information is copied on sheets of paper which are then electronically collated and inverted before being removed as a stack from the exit tray and placed upside down in the secondary tray for subsequent integration with sheets from the primary tray as coded information is printed. In an alternative method, the sheets of paper having non-coded information copied thereon are collected in the duplex tray with each sheet then being cycled through the system without copying or printing thereon so as to be inverted upon return to the duplex tray in preparation for printing of coded information. In a further alternative method, sheets of paper onto which the non-coded information has been copied are removed from the exit tray and thereafter selected from the secondary tray to make a complete set of copies which is thereafter used as originals to make further sets of copies.

Abstract: This is an electrophotographic process comprising the step of contacting a latent electrostatic image with a developer comprising carrier and toner. The carrier is a core coated with a continuous film of a fluoropolymer and a modifying resin. This carrier has a positive triboelectric charge with respect to the toner. This positive charge is obtained by curing the coated carrier at a temperature less than 700 DEG F.

Abstract: COMPONENT MOUNTING APPARATUS USEFUL FOR COMPACT COPIERS Electrical components in an elongated array are suspended within the interior of a sleeve type closed loop member such as a rotatable photoconductor drum or closed loop belt of a compact copier. Preferably some of the components are mounted on a board and held within the sleeve by edge slots or the like in sleeve mounting end caps, attached to the machine frame. A drive motor can be attached as part of the array and further can be arranged to drive a fan blade so that cooling air is forced through the sleeve and over the components so that the sleeve acts as a plenum. Power can be coupled from the drive motor through the end mounts to motivate the sleeve in the direction of its closed loop and/or apply power to other components of the copier. B0977072

Abstract: VECTOR PINNING IN AN ELECTROPHOTOGRAPHIC MACHINE Apparatus and method for pinning the value of a white, gray or otherwise colored, single-shaded vector in an electrophotographic machine. The vector is the value of the image voltage minus the developer voltage. Valuation of changes in the image voltage are obtained by 1) sensing the reflectivity of a developed single-shaded image and converting that into a representative voltage; 2) sensing the reflectivity of the bare photoconductor and converting that into a representative voltage; 3) obtaining a measure of the difference between the representative image and reference voltages; and4) noting changes in the difference. Pinning the vector calls for adjusting the developer voltage or document illumination intensity level an amount necessary to compensate for the change in image voltage.

Abstract: METHOD AND APPARATUS FOR ADAPTIVE COLLATION The invention concerns a method and apparatus for operating a multibin sheet collator, particularly a copier/collator installation. Additional to the number of sets to be collated, the number of sheets contained in each set is entered into the collator logic. If this number of sheets in a set exceeds the capacity of a single collator bin, adjacent bins are grouped together and treated as one virtual bin with increased capacity, thus extending the collator usage. Sheets exceeding the total capacity of the collator can be fed into additional receptacles.
