Abstract: Provided is an image forming system that can prevent unnecessary down time and spoiled paper from being caused, thereby improving productivity. The image forming system includes an image forming portion, a detecting portion, and a controlling portion. When an abnormality has been detected by the detecting portion, when a reading portion for reading an image formed on a recording medium by the printing operation of the image forming portion is provided, the controlling portion causes the reading portion to function to continue the printing operation, and at the detection of the abnormality on the basis of the read image, stops the printing operation to cause a notifying portion to perform notification related to the abnormality, and when the reading portion is not provided, the controlling portion stops the printing operation to cause the notifying portion to perform the notification related to the detected abnormality.

Abstract: Method and apparatus for producing a head drum for a video tape recorder and playback in which the head drum about which the tape passes is formed with a guide ledge so as to direct the tape past rotating magnetic heads and wherein the ledge is formed by cutting the surface of the head drums with a cutting tool and then providing a groove which undercuts the surface of the drum so as to form the ledge with a surface which is at right angles to the tangent of the tape engaging surface of the drum. By undercutting the surface of the drum to form the ledge assures that a radius will not be formed between the drum surface and the ledge, thus assuring accurate indexing of the lower edge of the video tape.
