Abstract: An separating and staging machine is disclosed which is used in conjunction with high speed document processing apparatus in which a succession of collations of insert material moving along an insert material feed path to an insert location are inserted into envelopes fed to the insert location. The machine of the present invention feeds envelopes from a storage hopper to a feed path which is long enough to accommodate a plurality of staging locations at which individual envelopes are maintained until one is fed to the insert location, after which the envelopes at each staging location are advanced to the next staging location, and a new envelope is fed from the storage hopper to the first of the staging locations. With this arrangement the distance between successive envelopes moving through the staging locations is approximately equal to the distance between successive collations moving along the insert material feed path, thereby increasing the rate at which envelopes can be fed to the insert location.

Abstract: A stack of envelopes has its lowermost envelope advanced from the stack by two sets of longitudinally spaced kick rollers, which are driven through a gear train by a unidirectional motor. A separator, which includes a feed roll and a restraint roll driven by the unidirectional motor, allows only one envelope to pass therethrough. The gear train includes two sets of interrupted teeth on a gear for stopping advancement of each of the two sets of kick rollers so that another envelope is not advanced from the stack during a cycle of operation. The gear has a third set of interrupted teeth for stopping the feed and restraint rolls after the envelope has passed the separator. The envelope is advanced to a printer by drive rolls, which cooperate with spring biased back-up rolls to form a nip, driven by the unidirectional motor. When the envelope enters the drive rolls, a latch holds the gear having the interrupted teeth from rotating.

Diverted media is advanced to a divert chute through which it can pass to a collecting bin.

Abstract: A method and a device for adjusting the printing position of a printer head. When a recordable medium having a greater thickness than that of a standard cut sheet of letter size paper is inserted in an electrophotographic apparatus, it is often necessary to increase the distance between the top recordable medium in the paper supply tray and the paper input port in the electrophotographic apparatus to allow a greater number of thick sheets of recordable medium to be loaded. One method of increasing the distance is to rotate a guide panel into a position that abuts the electrophotographic apparatus and increases the distance between the paper supply tray and the paper receiving port. Unfortunately, this causes the printer head to require adjustment, as the horizontal positioning of the printable medium fed into the printer has changed. This inventive method and device uses a sensor to determine when the guide panel has been rotated and automatically adjusts the printer head's position.

Abstract: This invention utilizes a simple mechanical buffer that will hold material and a two stage software buffering technique that controls the mechanical buffer to act as a First In First Out mechanical mechanism that allows other system events to be triggered off of dynamic thresholds. The two stage software buffering technique consists of a simple software FIFO with rule based logic to control input into a primary queue input and a secondary reserve queue which holds information as soon as it arrives. The decision to move information from the secondary reserve queue into the primary queue is based upon specific rules that are dynamically executed. This permits the creation of a dynamic threshold and allows the reliable triggering of the systems events. The foregoing permits material that is being produced at one fixed speed to be synchronized with material that is produced at variable speeds.

Abstract: A method and apparatus for conveying and staggering envelope contents includes a driven, substantially vertically positioned conveyor belt with an associated conveying slit, through which the envelope contents including documents to be staggered, are moved past an operator. On the side of the envelope contents opposite the conveyor belt (i.e., facing the operator) there is a non-rotary or slowly rotatable delay roller which can be pressed against the document facing it. The delay roller is preferably moved by an electromagnet. The friction between the delay roller and the document facing it is much greater than the friction between the two envelope contents, so that the front document facing the delay roller is decelerated, while the back document is advanced by the conveyor belt until the two documents are staggered. The operator can then detect whether or not there is a document behind the front document, and whether it is correctly oriented.

Abstract: An insert for preventing a gummed flap from adhering to an envelope while being printed upon in a laser printer is substantially nonadherent to moister-activated and/or heat-activated gums and adhesives. The nonadherent insert is made from sheet material which is configured to correspond to flaps of commonly used envelopes. The insert is positioned between the gummed flap and a body portion of an envelope to be printed upon prior to feeding the envelope into a laser printer. The insert prevents the gum of the flap, which may be activated by the heat inside a laser printer, from adhering to the body of the envelope. The insert is removed from the envelope after printing and may be repeatedly used.
