FO-3800M At the production line, the output power of the scanner unit is adjusted to 0.33 M ILL I-WAT T P L US 2 0 P C TS an d 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 MICROSEC. giving an acceptable emission level of 42 MICRO-WATT which is still-less than the limit of CLASS-1 laser product. Caution The fusing unit is hot. Exercise care when inspecting it.
