Important Safety Notices
Responsibilities of the Customer Engineer
Customer Engineer
Maintenance shall be done only by trained customer engineers who have completed
service training for the machine and all optional devices designed for use with the machine.
Reference Material for Maintenance
Maintenance shall be done using the special tools and procedures prescribed for
maintenance of the machine described in the reference materials (service manuals,
technical bulletins, operating instructions, and safety guidelines for customer
engineers).
In regard to other safety issues not described in this document, all customer engineers
shall strictly obey procedures and recommendations described the "CE Safety Guide".
Use only consumable supplies and replacement parts designed for use of the
machine.
Before Installation, 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
product. Before you move the product, arrange the power cord so it will not fall
under the product.
Power
Always disconnect the power plug before doing any maintenance procedure.
After switching off the machine, power is still supplied to the main machine
CÓPIA NÃO CONTROLADA
CÓPIA NÃO CONTROLADA
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, never touch electrical components or moving parts
(gears, timing belts, etc.).
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.
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.,
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.
Never use your fingers to check moving parts 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: 1) Switch the machine off, 2)
Disconnect the power plug from the power source.
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.
CÓPIA NÃO CONTROLADA
CÓPIA NÃO CONTROLADA
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.
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
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. For more details, please refer to Technical Bulletin "Silicone Oil
Removal" (A024-50).
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.
CÓPIA NÃO CONTROLADA
CÓPIA NÃO CONTROLADA
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
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 off the power and disconnect the power plug (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.
