IIMPORTANT 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. 4. If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components. 5. If the Start key is pressed before the copier completes the warm-up period (the Start key starts blinking red and green alternatively), keep hands away from the mechanical and the electrical components as the copier starts making copies as soon as the warm-up period is completed. 6. The inside and the metal parts of the fusing unit become extremely hot while the copier is operating. Be careful to avoid touching those components with your bare hands. HEALTH SAFETY CONDITIONS 1. Never operate the copier without the ozone filters installed. 2. Always replace the ozone filters with the specified ones at the specified intervals. 3. Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get medical attention. OBSERVANCE OF ELECTRICAL SAFETY STANDARDS 1. The copier and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those models. 2. The NVRAM on the system control board has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.
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. CAUTION MARKING:
