Polygon Motor : change forwrding angle of the laser beam towards the direction of main
scanning lines.
#1, #2 F-Theta Lens : Change the beam angle to be projected on the drum surfacein the
same size and interval.
Reflection Mirror : Change the direction of the laser beam
Sync Sensor : Determin the starting point of the projection
Sync Sensor : Determin the starting point of the projection

Laser Safety
The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-
based optical units in the field. The laser units can only be repaired in a factory or at a
location with the requisite equipment. The laser subsystem is replaceable in the field by a
qualified Customer Engineer. The inner parts are not repplaceable in the field. Customer
service engineers are therefore directed to return the complete laser unit to the factory or
service depot when replacement of the laser unit is required.

LSU NOTICE
This printer meets the requirements in DHHS 21 CFR Subchapter J of the United States of America,
and has been approved as a Class I laser product that meets the requirements in IEC 60825-1 in other
regions. Class I laser products are not defined as a hazardous product. This printer uses one AIGaAs
laser diode(L model) and two AIGaAs laser diodes(M/H model) with each power of 5 mW(L model) and
15mW(M/H model) and electromagnetic wave field of 770~795 nm(L model) and 770~800 nm(M/H model).
This laser system and the printer were designed to protect users from exposure to laser emissions of over
Class I when used or repaired in normal conditions.
Turn off the main power before starting the laser unit related work. The
