CAUTION This product is a class 1 laser product that complies with 21CFR 1040 of the CDRH standard and IEC825. This means that this machine does not produce hazardous laser radiation. The use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eye’s retina, there is the danger of spot damage to the retina.
At the production line, the output power of the scanner unit is adjusted to 0.57 MILLI-WATT PLUS 20 PCTS and is maintained constant by the operation of the Automatic Power Control (APC).

[6] COPY PROCESS An OPC drum is used for the photoconductor. (Structure of the OPC drum layers) OPC layer (20 microns thick) Pigment layer (0.2 to 0.3 microns thick) Aluminum drum 1.
2. Outline of print process Step-2: Exposure (laser beam, lens) This printer is a non-impact printer that uses a semiconductor laser and electrostatic print process. This printer uses an OPC (Organic Photo Conductor) for its photoconductive material. First, voltage from the main corona unit charges the drum surface and a latent image is formed on the drum surface using a laser beam. This latent image forms a visible image on the drum surface when toner is applied.
Step-3: Developing (DC bias) Step-4: Transfer A bias potential is applied to the MG roller in the two component magnetic brush developing method, and the toner is charged negative through friction with the carrier. The visible image on the drum surface is transferred onto the print paper by applying a positive charge from the transfer corona to the backside of the print paper.
Step-7: Optical discharge (Semiconductor laser) Start Before the drum rotation is stopped, the semiconductor laser is radiated onto the drum to reduce the electrical resistance in the OPC layer and eliminate residual charge, providing a uniform state to the drum surface for the next page to be printed. 1) Because the grid potential is at a low level, the drum potential is at about -400V. (Carrier may not be attracted though the carrier is pulled towards the drum by the electrostatic force of 400V.
[7] OPERATIONAL DESCRIPTIONS 1. Outline of operation The outline of operation is described referring to the basic configuration.
2. Scanner section A. Scanner unit Spectral sensitivity characteristics (Standard characteristics) The scanner unit in the digital copier scans images. Relative sensitivity It is composed of the optical unit and the drive unit. The optical unit performs scanning in the main scan direction with the light receiving elements (color CCD). The drive unit performs scanning in the sub scanning direction by moving the optical unit. B. Optical system Two white lamps are used as the light source.
3. Laser unit B. Laser beam path The image data sent from the MCU (image process circuit) is sent to the LSU (laser unit), where it is converted into laser beams. A. Basic structure The LSU unit is the writing section of the digital optical system. The semiconductor laser is used as the light source, and images are formed on the OPC drum by the polygon mirror and fθ lens, etc.
