DRYPIX4000 and DRYPIX7000 is different from other thermal dry-type printer is the key to the laser generator assembly, I encountered most of the cases is the laser generator assembly is damaged, that is, commonly referred to as the laser head is damaged _ need to be replaced. Laser head belongs to the consumables, there is a life expectancy, generally in the printing of about 100,000 sheets of film will be damaged. The laser head is damaged because the laser diode in the laser generator assembly is damaged by overheating or the power drops _ this laser dish. The power and wavelength of the pole tube has strict parameters, and the position of the laser tube only millimeter error, so it is difficult to repair the need to replace the entire laser generator assembly, including the optical system. It should be noted that in the replacement of components to the sub-scanning components (laser head under the drive part) together with the dismantling _ there are strict positional requirements, if the installation of the position of the offset too large will affect the image quality. Another reason for the above malfunction is that there is an obstruction under the laser head (e.g., a film jam or a broken film bag during loading) that blocks the laser beam, so that the laser detecting photosensitive element (e.g., SE1 in the DRYPIX7000) located in the sub-scanning assembly does not detect the laser beam. At this point disassemble the assembly _ remove the obstruction.
FUJIFILM CAMERA HISTORYFUJIFILM CORPORATION (hereinafter referred to as: FUJIFILM) since its founding in 1934, has continued to move forward at a determined pace, and has grown to become one of the world's largest comprehensive imaging, information, and document processing products and services manufacturer and supplier.

Fujifilm has three major business fields, namely: 1. the imaging business field, which consists of two product groups, traditional and digital (film, cameras, photographic paper, chemicals, processing equipment, etc.); 2. the information business field, which consists of a range of products, including printing systems, medical systems, liquid crystal materials, and recording media; and 3. document processing equipment (copiers, printers, multifunctional digital printing centers, and consumables), which are manufactured and sold by Fujifilm's subsidiary Fuji Xerox Corporation. Fuji Xerox, a subsidiary of Fujifilm, manufactures and sells document processing equipment (copiers, printers, multifunctional digital printing centers, consumables, etc.) in the document business field.
