Lithium Batteries
Incorrect replacement of lithium battery(s) on the FCU, controller board and memory board
unit may pose risk of explosion. Replace only with the same type or with an equivalent type
recommended by the manufacturer. Discard used batteries in accordance with the
manufacturer's instructions.
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.
