Abstract: A solid ink stick supply system and related method for delivering solid ink sticks to an ink jet print head reservoir is disclosed. The supply system includes a housing with a keyed plate that guides the ink sticks into the proper loading position in a supply channel. A pusher rod in the supply channel transfers an ink stick onto an endless belt for delivery to the print head reservoir. A push device on the endless belt engages and delivers the ink stick to the print head reservoir. A second ink stick is transferred from the supply channel to the endless belt and is retained on the belt by a stop device. A method for efficiently loading ink sticks into the supply system is also provided.

Abstract: Apparatus for defining a bank of sequential windows from a raster-scanned image of a document for storage in a data base. In addition, the apparatus includes a look-up table for each window wherein the bit pattern of the window is used to determine the correction factor which is applied to the next window as the "new" bit from a set of patterns and correction factors derived from well known algorithms developed to minimize the amount of data needed to electronically recreate a given document. The apparatus also includes storage devices to permit the application of the algorithm in overlapping pieces over the face of the document.

Abstract: A method and apparatus for removing undesirable dots and voids which are smaller than the user defined smallest data item of a bit-map image of a picture being scanned by a picture coding system. The bit-map is delayed as it is being generated to form a series of tessellations or windows of data of selected sizes. The windows are propagated through a series of neighborhood-logic elements which with the output data level of the outer ring of neighborhood-logic elements which define the window being examined to determine if those data levels are all of the same sense. If they are all of the same sense, then all of the neighborhood-logic elements which define the interior of the window are set or cleared so that the output data levels of all of the neighborhood-logic elements which define the window are of the same sense.
