Safe and Ecological Disposal
1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly if exposed to an open
flame.
2. Dispose of used toner, developer, and organic photoconductors in accordance with local
regulations. (These are nontoxic 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.
• Use of controls not specified in this manual, or performance of adjustments or procedures not
specified in this manual, may result in hazardous radiation exposure.
• Do not use the cleaner to suck spilled toner (including used toner). Sucked toner may cause firing
or explosion due to electrical contact flickering inside the cleaner. However, it is possible to use the
cleaner designed for dust explosion-proof purpose. If toner is spilled over the floor, sweep up
spilled toner slowly and clean remainder with wet cloth.
