During Maintenance

General

• Before you begin a maintenance procedure: 1) Switch the machine off, 2) Disconnect the power

plug from the power source, 3) Allow the machine to cool for at least 10 minutes.

• Avoid touching the components inside the machine that are labeled as hot surfaces.

Safety Devices

• Never remove any safety device unless it requires replacement. Always replace safety devices

immediately.

• Never do any procedure that defeats the function of any safety device. Modification or removal of

a safety device (fuses, switches, etc.) could lead to a fire and personal injury. Always test the

operation of the machine to ensure that it is operating normally and safely after removal and

replacement of any safety device.

• For replacements use only the correct fuses or circuit breakers rated for use with the machine. Using

replacement devices not designed for use with the machine could lead to a fire and personal

injuries.

Organic Cleaners

• During preventive maintenance, never use any organic cleaners (alcohol, etc.) other than those

described in the service manual.

• Make sure the room is well ventilated before using any organic cleaner. Use organic solvents in

small amounts to avoid breathing the fumes and becoming nauseous.

• Switch the machine off, unplug it, and allow it to cool before doing preventive maintenance. To

avoid fire or explosion, never use an organic cleaner near any part that generates heat.

• Wash your hands thoroughly after cleaning parts with an organic cleaner to prevent contamination

of food, drinks, etc. which could cause illness.

• Clean the floor completely after accidental spillage of silicone oil or other materials to prevent

slippery surfaces that could cause accidents leading to hand or leg injuries. Use "My Ace" Silicone

Oil Remover (or dry rags) to soak up spills.

Lithium Batteries

• Always replace a lithium battery on a PCB with the same type of battery prescribed for use on that

board. Replacing a lithium battery with any type other than the one prescribed for use on the board

could lead to an explosion or damage to the PCB.

• Never discard used batteries by mixing them with other trash. Remove them from the work site and

dispose of them in accordance with local laws and regulations regarding the disposal of such

items.

Ozone Filters

• Always replace ozone filters as soon as their service life expires (as described in the service

manual).

• An excessive amount of ozone can build up around machines that use ozone filters if they are not

replaced at the prescribed time. Excessive ozone could cause personnel working around the

machine to feel unwell.

• To avoid possible accumulation of ozone in the work area, locate the machine in a large well

ventilated room that has an air turnover rate of more than 50 m3/hr/person.

Power Plug and Power Cord

• Before servicing the machine (especially when responding to a service call), always make sure that

the power plug has been inserted completely into the power source. A partially inserted plug could

lead to heat generation (due to a power surge caused by high resistance) and cause a fire or other

problems.

• Always check the power plug and make sure that it is free of dust and lint. Clean it if necessary. A

dirty plug can generate heat which could cause a fire.

• Inspect the length of the power cord for cuts or other damage. Replace the power cord if

necessary. A frayed or otherwise damaged power cord can cause a short circuit which could lead

to a fire or personal injury from electrical shock.

• Check the length of the power cord between the machine and power supply. Make sure the power

cord is not coiled or wrapped around any object such as a table leg. Coiling the power cord can

cause excessive heat to build up and could cause a fire.

• Make sure that the area around the power source is free of obstacles so the power cord can be

removed quickly in case of an emergency.

• Make sure that the power cord is grounded (earthed) at the power source with the ground wire on

the plug.

• Connect the power cord directly into the power source. Never use an extension cord.

• When you disconnect the power plug from the power source, always pull on the plug, not the

cable.

After Installation, Servicing

Disposal of Used Items

• Never incinerate used toner, toner cartridges, or toner bottles.

• Toner, toner cartridges, or toner bottles thrown into a fire can ignite or explode and cause serious

injury. At the work site always carefully wrap used toner and toner cartridges with plastic bags to

avoid spillage before disposal or removal.

• Always dispose of used items (developer, toner, toner cartridges, OPC drums, etc.) in accordance

with the local laws and regulations regarding the disposal of such items.

• To protect the environment, never dispose of this product or any kind of waste from consumables at

a household waste collection point. Dispose of these items at one of our dealers or at an

authorized collection site.

• Return used selenium drums to the service center for handling in accordance with company policy

regarding the recycling or disposal of such items.

Points to Confirm with Operators

At the end of installation or a service call, instruct the user about use of the machine. Emphasize the

following points.

• Show operators how to remove jammed paper and troubleshoot other minor problems by

following the procedures described in the operating instructions.

• Point out the parts inside the machine that they should never touch or attempt to remove.

• Confirm that operators know how to store and dispose of consumables.

• Make sure that all operators have access to an operating instruction manual for the machine.

• Confirm that operators have read and understand all the safety instructions described in the

operating instructions.

• Demonstrate how to turn the machine off with the power button on the left front corner of the

machine. A message alerts the operator that there will be a slight delay until the machine shuts

down. This gives the hard disk time to stop rotating and shut down normally before the machine

loses power.

• Demonstrate how to disconnect the power plug quickly (by pulling the plug, not the cord) if any of

the following events occur: 1) something has spilled into the product, 2) service or repair of the

product is necessary, 3) the product cover has been damaged.

• Caution operators about removing paper fasteners around the machine. They should never allow

paper clips, staples, or any other small metallic objects to fall into the machine.

Special Safety Instructions for Toner

Accidental Physical Exposure

• 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.

Handling and Storing Toner

• Toner, used toner, and developer are extremely flammable.

• Never store toner, developer, toner cartridges, or toner bottles (including empty toner bottles or

cartridges) in a location where they will be exposed to high temperature or an open flame.

• 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.

Toner Disposal

• Never attempt to incinerate toner, used toner, or empty toner containers (bottles or cartridges).

Burning toner can explode and scatter, causing serious burns.

• Always wrap used toner and empty toner bottles and cartridges in plastic bags to avoid spillage.

Follow the local laws and regulations regarding the disposal of such items.

• Dispose of used toner and toner cartridges at one of our dealers or at an authorized collection site.

Always dispose of used toner cartridges and toner bottles in accordance with the local laws and

regulations regarding the disposal of such items.
