15. 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.
16. 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.
17. For machines installed with the ADF/ARDF:
When a thick book or three-dimensional original is placed on the exposure glass and the
ARDF cover is lowered, the back side of the ARDF rises up to accommodate the original.
Therefore, when closing the ARDF, please be sure to keep your hands away from the
hinges at the back of the ARDF.
18. When using a vacuum cleaner around the machine, keep others away from the cleaner,
especially small children.
19. For machines installed with the anti-tip components:
The anti-tip components are necessary for meeting the requirements of IEC60950-1, the
international standard for safety. The aim of these components is to prevent the products,
which are heavy in weight, from toppling as a result of people running into or leaning onto
the products, which can lead to serious accidents such as persons becoming trapped
under the product. (U.S.: UL60950-1, Europe: EN60950-1) Therefore, removal of such
components must always be with the consent of the customer. Do not remove them at your
own judgment.
20. NEVER touch the AC circuits on the PSU board to prevent electric shock caused by
residual charge. Residual charge of about 100V-400V remains in the AC circuits on the
PSU board for several months even when the board has been removed from the machine
after turning off the machine power and unplugging the power cord.
Health Safety Conditions
21. For the machines installed with the ozone filters:
•
Never operate the machine without the ozone filters installed.
•
Always replace the ozone filters with the specified types at the proper intervals.
22. The machine, which use high voltage power source, can generate ozone gas. High ozone
density is harmful to human health. Therefore, locate the machine in a large well ventilated
room that has an air turnover rate of more than 50m
3
/hr/person.
23. Toner and developer are 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.
