1.  SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL 
Do not incinerate toner bottles or used toner. Toner dust may ignite 
suddenly when exposed to an open flame. 
2.  Dispose of used toner, developer, and organic photoconductors in 
accordance with local regulations. (These are non-toxic supplies.) 
3.  Dispose of replaced parts in accordance with local regulations. 
4.  When keeping used lithium batteries in order to dispose of them later, do not 
put more than 100 batteries per sealed box. Storing larger numbers or not 
sealing them apart may lead to chemical reactions and heat build-up. 
 
LASER SAFETY 
The Center for Devices and Radiological Health (CDRH) prohibits the repair of 
laser-based optical units in the field. The optical housing unit 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 laser chassis is not 
repairable in the field. Customer engineers are therefore directed to return all 
chassis and laser subsystems to the factory or service depot when replacement of 
the optical subsystem is required. 
WARNING 
Use of controls, or adjustment, or performance of procedures other than 
those specified in this manual may result in hazardous radiation exposure. 
 
WARNING 
WARNING: Turn off the main switch before attempting any of the 
procedures in the Laser Unit section. Laser beams can seriously damage 
your eyes.
