1.2 BEFORE INSTALLATION, MAINTENANCE

1.2.1 SHIPPING AND MOVING THE MACHINE

!CAUTION

1. Work carefully when lifting or moving the machine. If the machine is heavy,

two or more Service Technicians may be required to prevent injuries (muscle

strains, spinal injuries, etc.) or damage to the machine if it is dropped or

tipped over.

2. Personnel moving or working around the machine should always wear proper

clothing and footwear. Never wear loose fitting clothing or accessories

(neckties, loose sweaters, bracelets, etc. ) or casual footwear (slippers,

sandals, etc.) when lifting or moving the machine.

3. Always unplug the power cord from the power source before you move the

product. Before you move the product, arrange the power cord so it will not

fall under the product.

4. The wall outlet should be near the copier and easily accessible.

1.2.2 POWER

!Warning

1. Always disconnect the power plug before doing any maintenance procedure.

After switching off the machine, power is still supplied to the main machine

and other devices. To prevent electrical shock, switch the machine off, wait

for a few seconds, then unplug the machine from the power source.

2. Before you do any checks or adjustments after turning the machine off, work

carefully to avoid injury. After removing covers or opening the machine to do

checks or adjustments, never touch electrical components or moving parts

(gears, timing belts, etc.).

3. After turning the machine on with any cover removed, keep your hands away

from electrical components and moving parts. Never touch the cover of the

fusing unit, gears, timing belts, etc.

1.2.3 INSTALLATION, DISASSEMBLY, AND ADJUSTMENTS

!CAUTION

1. After installation, maintenance, or adjustment, always check the operation of

the machine to make sure that it is operating normally. This ensures that all

shipping materials, protective materials, wires and tags, metal brackets, etc.,

removed for installation, have been removed and that no tools remain inside

the machine. This also ensures that all release interlock switches have been

restored to normal operation.

2. Never use your fingers to check moving parts causing spurious noise. Never

use your fingers to lubricate moving parts while the machine is operating.

1.2.4 SPECIAL TOOLS

!CAUTION

1. Use only standard tools approved for machine maintenance.

2. For special adjustments, use only the special tools and lubricants described

in the service manual. Using tools incorrectly, or using tools that could

damage parts, could damage the machine or cause injuries.

1.3 DURING MAINTENANCE

1.3.1 GENERAL

!CAUTION

1. Before you begin a maintenance procedure:

• Switch the machine off.

• Disconnect the power plug from the power source.

• Allow the machine to cool for at least 10 minutes.

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

surfaces.

3. The wall outlet should be near the copier and easily accessible.

1.3.2 SAFETY DEVICES

!WARNING

1. Never remove any safety device unless it requires replacement. Always

replace safety devices immediately.

2. Never do any procedure that defeats the function of any safety device.

Modification or removal of a safety device (fuse, switch, 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.

3. 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.

!CAUTION: DOUBLE POLE/NEUTRAL FUSING

The machine power cord must be disconnected from the power source

before replacement of FU002.

1.3.3 ORGANIC CLEANERS

!CAUTION

1. During preventive maintenance, never use any organic cleaners (alcohol,

etc.) other than those described in the service manual.

2. 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.

3. 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.

4. Wash your hands thoroughly after cleaning parts with an organic cleaner to

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

5. 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. For more details, please refer to Technical Bulletin “Silicone Oil

Removal” (A024-50).

1.3.4 LITHIUM BATTERIES

!WARNING

1. 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.

2. 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.

1.3.5 OZONE FILTERS

!CAUTION

1. 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.

2. Never operate the copier without the ozone filters installed.

1.3.6 POWER PLUG AND POWER CORD

!WARNING

1. Before serving 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. Make sure that the power cord is grounded (earthed) at the power source

with the ground wire on the plug.

7. Connect the power cord directly into the power source. Never use an

extension cord.

8. When you disconnect the power plug from the power source, always pull on

the plug, not the cable.

1.4 AFTER INSTALLATION, SERVICING

1.4.1 DISPOSAL OF USED ITEMS

!WARNING

Never incinerate used toner or toner cartridges. Toner or toner cartridges 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.

!CAUTION

1. 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.

2. 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.

3. Return used selenium drums to the service center for handling in accordance

with company policy regarding the recycling or disposal of such items.
