摘要： A difference in feed roller diameter from one printer to another causes a media to advance by a different amount for a given rotation of a drive shaft to which the feed roller is coupled. Such variation in advance distance is a linefeed error. Mean linefeed error is determined and corrected by printing a test plot having several areas. Each area is formed of the same image pattern, but is printed at a different linefeed error adjustment to compensate for mean linefeed error. The different adjustments are prescribed and span a typical compensation range for a given print engine model. The different adjustment factors cause banding to occur in some areas. The user picks one of the test pattern areas which has the highest print quality (i.e., least or no banding). The linefeed adjustment factor corresponding to such area is used for normal printing.

摘要： A line spacing mechanism for printing machines comprises an electric motor which is operable to rotate selectively in either direction. A worm on the shaft of the motor meshes with a helicoidally toothed wheel to cause a platen roller to rotate in the clockwise direction or the anticlockwise direction. The motor is support pivotally by trunions and urged by a spring to eliminate radial play between the worm and toothed wheel. Another spring, lever and ball apply thrust to the motor shaft to take up axial play in its bearing, i.e. between the worm and the motor.

摘要： A line feed ratchet arrangement is disclosed which allows selectability between two different line feeds such as the 5 1/3 lines per inch and six lines per inch and utilizes a drive pawl arrangement having two pawls driven identically. The drive ratchets are selectively engaged by coaxial shifting of a drive member in response to operator movement of a selector knob or similar control.

摘要： A method of forming a high-quality image on an elongated recording medium, such as a roll of paper sheet. When an image includes a character which stretches between two print regions, a blank line portion of the image is detected. When image forming operation is performed for forming a portion of the image up to the blank line, sheet feed operations are performed. Then, image forming operation for a remaining portion of the image is performed. Because the sheet feed operation will not be performed in the middle of printing of such image, undesirable broken line or gap will not be formed on the printed image.
