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). Even if the APC circuit fails in operation for some reason, the maximum output power will only be 15 MILLI-WATT 0.1 MICRO-SEC. Giving and accessible emission level of 42 MICRO-WATT which is still-less than the limit of CLASS-1 laser product. Caution This product contains a low power laser device.

[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. Non-image area of the drum surface charged with negative potential repel the toner, whereas the laser exposed portions where no negative charges exist, attract the toner. As a result, a visible image appears on the drum surface.
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. When the electrical resistance is reduced, positive charges on the aluminum layer are moved and neutralized with negative charges on the OPC layer.

(Basic configuration) (Option) Operation section FAX FAX modem Scanner section (Option) CCD Network Network Box FAX I/F USB Printer/ Scanner I/F MCU (Main control/image process section) PC USB or parallel Note: The scanner function is effective only by USB connection. Network is for print only.
2. Scanner section A. Scanner unit The scanner unit in the digital copier scans images. 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. Light radiated from the light source is applied to the document on the document table.
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.

Outline The operation circuit is composed of the LCD control circuit, the key matrix circuit, the display matrix circuit, and the buzzer circuit, realizing the U/I functions. The carriage unit is provided with the CCD PWB, the inverter PWB, the lamps, etc. A document is radiated, and image data read by the CCD are A/D converted to be sent to the ASIC. b. LCD control circuit b. CCD PWB The character LCD (COG) in 2 lines and 16 digits is used.
Since the AC power is directly rectified, if there were not this rush current prevention resistor (TH001), an extremely large rush current would flow due to a charging current flowing through the smoothing capacitor C006 when turning on the power. To prevent against this, the rush current prevention resistor TH001 is provided between the rectifying diode D003 and the smoothing diode C006, suppressing a rush current.
