Safety Notices

Prevention of Physical Injury

1. Before disassembling or assembling parts of the machine and peripherals, make sure that the machine power cord is unplugged.
2. The wall outlet should be near the machine and easily accessible.
3. 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.
4. The machine drives some of its components when it completes the warm-up period. Be careful to keep hands away from the mechanical and electrical components as the machine starts operation.
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.

Health Safety Conditions

Toner is 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

The machine and its peripherals must be serviced by a customer service representative who has completed the training course on those models.

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.
• To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and aerosols. A fire or an explosion might occur.
1
• The Controller board on the MF model contains a lithium battery. The danger of explosion exists if a battery of this type is incorrectly replaced. Replace only with the same or an equivalent type recommended by the manufacturer. Discard batteries in accordance with the manufacturer's instructions and 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 the cleaner to suck spilled toner (including used toner). Sucked toner may cause firing or explosion due to electrical contact flickering inside the cleaner. However, it is possible to use the cleaner designed for dust explosion-proof purpose. If toner is spilled over the floor, sweep up spilled toner slowly and clean remainder with wet cloth.

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.
2
• Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.
• Turn off the main switch before attempting any of the procedures in the Laser Optics Housing Unit section. Laser beams can seriously damage your eyes.

PM Intervals

PM Parts

There are no PM parts in this machine.
• Other than the three Yield Parts listed below, there are essentially no PM parts required for this product.
• These three items will need to be replaced in cases where their yield is near, however, given the ACV (Average Copy Volume) for this product, these "yield parts*1 " are expected to outlast the working life of the machine.
*1 "Yield Parts": Parts whose expected yield is longer than the machine lifetime when taking into consideration the machine's ACV.
Description Expected Yield Q'ty/unit
Paper Feed Roller 120 K prints 1
Transfer Roller 120 K prints 1
Fusing Unit 120 K prints 1

Yield Counter

Yield counters for each yield part can be checked by the following methods.
Configuration Page in the “Print List/Report” menu
21
3. Preventive Maintenance
Web Image Monitor
• The machine displays "Fuser life end notice", "Transfer roller life end notice" or "Life End of Paper Feed Roller Unit" when one of these counters reaches each yield.
Counter Reset
The process below shows how to reset the yield counters.
1. Enter the "Maintenance mode".
2. Select "Engine Maintenance", and then press "OK" key.
3. Select "Reset Fuser Unit", "Reset Transfer Unit" or "Reset Paper Feed Rol Life" and then press "OK" key.
4. Press the left key “Execute” of the “Selection keys”.
5. Exit the "Maintenance mode".
