Page 21: Important Safety Notices
IMPORTANT SAFETY NOTICES PREVENTION OF PHYSICAL INJURY 1. Before disassembling or assembling parts of the copier and peripherals, make sure that the copier power cord is unplugged. 2. The wall outlet should be near the copier and easily accessible. 3. Note that some components of the copier and the paper tray unit are supplied with electrical voltage even if the main power switch is turned off.
Page 22: Laser Safety
NOTES SAFETY AND ECOLOGICAL FOR DISPOSAL 1. 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.
