Quiklaze, Polaris, Tempest, UP-213, etc.), HOYA (HOYA 2100, HSL-4000, HSL-5000 series, etc.) ) have a wealth of maintenance experience.
The laser driver circuit includes the laser beam generator and modulation circuit, optical modulation device, scanning motor control and drive circuit, these parts of the circuit and device are housed in a laser enclosure, generally referred to as the laser. Laser drive circuit failure is mainly manifested in the following three aspects:
①Laser beam generator (laser head) failure. Laser beam generator (laser head) failure refers to laser diode failure, mainly laser diode damage, focusing lens (in order to broaden the modulation band of the laser beam, the laser beam must be focused) on the aging of the coating and so on, resulting in a decline in laser power or instability and other fault phenomena. This fault checking method is to open the machine, remove the laser, and then open the laser cover, use a multimeter to directly measure the DC resistance value of the laser (there are three pins). Check whether the coating on the surface of the focusing lens is aging, dust or spots.
②Scanning motor control and drive circuit failure. In order for the laser beam from the laser generator to scan the entire length of the light-sensitive component, the laser beam must be deflected, and thus a scanning mirror driven by a motor is used. This is a positive polygonal column with the side of the mirror, and driven by the motor for high-speed rotation of the multi-faceted mirror, but also by a number of mirrors (depending on the model of the machine has 2 to 6 mirrors) and the motor assembled into a single combination. This motor is called an att motor. When the att motor speed abnormality occurs, the laser beam can not be modulated properly, resulting in laser power problems. This fault checking method is to open the machine, take out the laser, and then open the cover of the laser, rotate the scanning mirror by hand (pay attention to the hand do not touch the mirror), observe the scanning mirror is rotating freely, its axis has no astringent or stuck feeling.
3 laser beam transmission channel failure. Laser beam transmission channel refers to the laser beam issued by the laser after focusing lens focusing, through a series of scanning mirrors, scanning lenses, laser beam detector mirror modulation, and then launched by the mirror to the photoreceptor drum to form a two-dimensional latent image, when the laser beam transmission channel failure, the laser will appear scattered. The check method for this failure is to open the machine, remove the laser, and then open the cover of the laser, check the inside of the optics with or without toner, dust and so on. In addition there are laser systems Newwave (Ezlaze, Quiklaze, Polaris, Tempest, UP-213, etc.), HOYA (HOYA 2100, HSL-4000, HSL-5000 series, etc.), etc., in addition to the laser is equipped with a mirror inside the frame is also equipped with a reflector, this time it should also be the Reflector should be removed for inspection.
