The main machine and options can be installed by either the customer or customer engineer. The customer

or customer engineer must follow the installation instructions described in the operating instructions.

- Reference Material for Maintenance -

Maintenance shall be done with the special tools and the procedures prescribed for maintenance of the

machine described in the reference materials (service manuals, technical bulletins, operating instructions,

and safety guidelines for customer engineers).

• Use only consumable supplies and replacement parts designed for use with the machine.

Before Installation or Maintenance

- Shipping and Moving the Machine -

• Work carefully when lifting or moving the machine. If the machine is heavy, two or more customer

engineers may be required to prevent injuries (muscle strains, spinal injuries, etc.) or damage to the

machine if it is dropped or tipped over.

• 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.

• Always unplug the power cord from the power source before you move the machine. Before you

move the machine, arrange the power cord so it will not fall under the machine.

- Power -

• Always turn the machine off and disconnect the power plug before doing any maintenance procedure.

After turning the machine off, 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.

• 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, avoid touching electrical

components or moving parts (gears, timing belts, etc.).

• After turning the machine on with any cover removed, keep your hands away from electrical com-

ponents and moving parts. Never touch the cover of the fusing unit, gears, timing belts, etc.

- Installation, Disassembly, and Adjustments -

• 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., (attached to protect the machine during shipping), have been removed

and that no tools remain inside the machine.

• Never use your fingers to check moving parts that are causing spurious noise. Never use your fingers

to lubricate moving parts while the machine is operating.

- Special Tools -

• Use only standard tools approved for machine maintenance.

• 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.

During Maintenance

- General -

• Before you begin a maintenance procedure always switch the machine off.

• Disconnect the power plug from the power source.

• 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 (a fuse, thermistor, etc.) unless it requires replacement. Always

replace a safety device immediately.

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

safety device (fuse, thermistor, etc.) could cause a fire and personal injury. After removal and re-

placement of any safety device, always test the operation of the machine to ensure that it is operating

normally and safely.

• For replacement parts use only the correct fuses, thermistors, circuit breakers, etc. rated for use with

the machine. Using replacement devices not designed for use with the machine could cause a fire

and personal injuries.

- Organic Cleaners -

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

scribed in the service manual. (Refer the “2. Preventive Maintenance” in the Service Manual.)

• Make sure the room is well ventilated before using any organic cleaner. Always 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 component that generates heat.

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

food, drinks, etc. which could cause illness.

- 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.

- Power Plug and Power Cord -

• 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.

• 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.
