Important Safety Notices

Important Safety Notices

Prevention of Physical Injury

1.Before disassembling or assembling parts of the main machine and peripherals, make sure that the power cord of the main machine is unplugged.

2.The wall outlet should be near the machine and easily accessible.

3.Note that some components of the machine 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.The inside and the metal parts of the fusing unit become extremely hot while the machine is operating. Be careful to avoid touching those components with your bare hands.

•To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and aerosols.

Health Safety Conditions

1.Toner and developer is non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Immediately wash eyes with plenty of water. If unsuccessful, get medical attention.

2.This machine, which uses a high voltage power source, can generate ozone gas. High ozone density is harmful to human health. Therefore, the machine must be installed in a well-ventilated room.

Observance of Electrical Safety Standards

1.This machine and its peripherals must be serviced 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.

Handling Toner

•Work carefully when removing paper jams or replacing toner bottles or cartridges to avoid spilling toner on clothing or the hands.

•If toner is inhaled, immediately gargle with large amounts of cold water and move to a well ventilated location. If there are signs of irritation or other problems, seek medical attention.

•If toner gets on the skin, wash immediately with soap and cold running water.

•If toner gets into the eyes, flush the eyes with cold running water or eye wash. If there are signs of irritation or other problems, seek medical attention.

•If toner is swallowed, drink a large amount of cold water to dilute the ingested toner. If there are signs of any problem, seek medical attention.

•If toner spills on clothing, wash the affected area immediately with soap and cold water. Never use hot water! Hot water can cause toner to set and permanently stain fabric.

•Always store toner and developer supplies such as toner and developer packages, cartridges, and bottles (including used toner and empty bottles and cartridges) out of the reach of children.

•Always store fresh toner supplies or empty bottles or cartridges in a cool, dry location that is not exposed to direct sunlight.

•Do not use a vacuum cleaner to remove spilled toner (including used toner). Vacuumed toner may cause a fire or explosion due to sparks or electrical contact inside the cleaner. However, it is possible to use a cleaner designed to be dust explosion-proof. If toner is spilled over the floor, sweep up spilled toner slowly and clean up any remaining toner with a wet cloth.

Safety and Ecological Notes 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, the maintenance unit which includes developer or the organic photoconductor 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.

Instructions for the Customers

Provide instructions on the following matters to customers. For detailed procedures, see the user manuals.

•Operating the printer function

•Installing consumables and loading paper

•Operating the main power switch

•Removing jammed paper

•Registering/changing/deleting data in the address book

•Providing precautions on use

•Connecting to computers (such as configuring the port setting)

•Giving a brief outline of the tabs in the drivers

Moving the Machine

•It is dangerous to handle the power cord plug with wet hands. Doing so could result in electric shock.

•Unplug the power cord from the wall outlet before you move the machine. While moving the machine, take care that the power cord is not damaged under the machine. Failing to take these precautions could result in fire or electric shock.

26

Main Machine Installation

•If you have to move the machine when the optional paper tray unit is attached, do not push on the main unit's top section. Doing so can cause the optional paper tray unit to detach, possibly resulting in injury.

•When disconnecting the power cord from the wall outlet, always pull the plug, not the cord. Pulling the cord can damage the power cord. Use of damaged power cords could result in fire or electric shock.

•The machine weighs approximately 22.5 kg (49.6 lb.). When moving the machine, use the inset grips on both sides, and lift slowly in pairs. The machine will break or cause injury if dropped.

•Do not hold the control panel while moving the machine. Doing so may damage the control panel, cause a malfunction, or result in injury.

•Be careful when moving the machine. Take the following precautions:

•Close all covers and trays, including the front cover and by-pass tray.

•If optional paper feed units are attached, remove them from the machine and move them separately.

•Keep the machine level and carry it carefully, taking care not to jolt or tip it. Rough handling may cause a malfunction or damage the hard disk or memory, resulting in loss of stored files.
