Info

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. The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing. 1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not as individual parts. 2) Do not look into the machine with the main switch turned on after removing the developer unit, toner cartridge, and drum cartridge. 3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing the optical system. 4) The middle frame contains the safety interlock switch. Do not defeat the safety interlock by inserting wedges or other items into the switch slot. LASER WAVE – LENGTH : 770 ~ 795nm Pulse times : 12.88µs ± 12.88ns/7mm Out put power : MAX 0.2mW CAUTION INVISIBLE LASER RADIATION, WHEN OPEN AND INTERLOCKS DEFEATED. AVOID EXPOSURE TO BEAM.

At the production line, the output power of the scanner unit is adjusted to 0.18 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. The foregoing is applicable only to the 220V model, 230V model and 240V model. Caution This product contains a low power laser device. To ensure continued safety do not remove any cover or attempt to gain access to the inside of the product. Refer all servicing to qualified personnel. VAROITUS!
