摘要： An image forming apparatus is provided with sensors for detecting existence of sheets of paper at a plurality of positions in transport paths within the image forming apparatus. A circuit part counts a number of sheets of paper remaining within the image forming apparatus when a transport abnormality occurs based on outputs of the sensors. This number of sheets of paper remaining within the image forming apparatus when the transport abnormality occurs is displayed on a display.

摘要： An image forming apparatus includes an image data processor, an image forming part, and a sequence controller for controlling an image forming operation of the image forming part. The image data processor transmits to the sequence controller a print start signal which instructs a start of the image forming operation of the image forming part every time the image data is prepared in the image data processor regardless of whether or not the image forming part is in a ready state in which the image forming part is ready to carry out the image forming operation. The sequence controller includes a memory for storing the print start signal from the image data processor and a part for supplying the stored print start signal and the image data from the image data processor to the image forming means. The memory has a memory capacity for storing a plurality of print start signals.

摘要： A laser beam scanning system includes a laser for emitting a laser beam modulated with image information to be recorded and a deflecting device, such as polygon mirror, for deflecting the laser beam over a predetermined angle repetitively, so that the laser beam is scanned on a scanning surface, thereby an image is formed on the scanning surface. When a plurality of laser beams are used at the same time, the plurality of laser beams are arranged in an array inclined with respect to the scanning direction. In this case, a sync sensor generates a sync signal in response to a laser beam received in the first place. When a polygon mirror is so structured to have a reflecting surface which is defined by a curved surface having a predetermined radius of curvature, a f.theta. lens may be discarded. In this case, when a transparent layer is formed on this curved reflecting surface, no distortion in scanning speed is produced even without using any electrical correction. Besides, it is also preferable to control the intensity of laser beam so as to maintain the image density of a resultant image at constant.
摘要翻译： 激光束扫描系统包括用于发射用待记录的图像信息调制的激光束的激光器和诸如多面镜的偏转装置，用于使激光束重复地偏转预定角度，使得激光束被扫描 扫描表面，从而在扫描表面上形成图像。 当同时使用多个激光束时，多个激光束被布置成相对于扫描方向倾斜的阵列。 在这种情况下，同步传感器响应于首先接收的激光束产生同步信号。 当多面镜被构造为具有由具有预定曲率半径的曲面限定的反射表面时，可以丢弃fθ透镜。 在这种情况下，当在该弯曲反射面上形成透明层时，即使不进行任何电校正，也不会产生扫描速度的变形。 此外，还优选控制激光束的强度，以便使得到的图像的图像浓度保持恒定。
