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 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, 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. 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 RAM board on the main control board has a lithium battery which can explode if replaced incorrectly. Replace the battery only with an identical one. The manufacturer recommends replacing the entire RAM board. Do not recharge or burn this battery. Used batteries must be handled in accordance with local regulations. SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL 1. Do not incinerate the toner bottle or the used toner. Toner dust may ignite suddenly when exposed to open flame. 2. Dispose of used toner, developer, and organic photoconductor according to 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. A204/A206/A207/A208/A210/A211 COPIER SERVICE MANUAL The A204 copier is based on the A153 copier. The A206 copier is based on the A155 copier. The A207 copier is based on the A156 copier. The A208 copier is based on the A157 copier. The A210 copier is based on the A159 copier. The A211 copier is based on the A160 copier. Only the differences from the base copiers are described in the following pages.
