CAUTION
Do not pull the power cord when removing it from the outlet. If the power cord is pulled, the wires may
become broken and there is a danger of fire or electrical shock. (Always grasp the power plug when
removing the power cord from the outlet.)
Always remove the power plug from the outlet when moving the machine. If the power cord is
damaged, there is a danger of fire or electrical shock.
Always hold the designated parts only when lifting or moving the machine.
If this machine will be left unused for an extended period (e.g. overnight), turn it off at the main power
switch. If the machine will not be used for an even longer period of time (e.g. vacation), remove the
power plug from the outlet as a safety precaution. If the optional Fax kit is installed, note that turning
the machine off at the main power switch disables fax transmission and reception.
For safety purposes, always remove the power plug from the outlet when performing cleaning
operations.
If dust accumulates within the machine, there is a danger of fire or other trouble. It is therefore
recommended that you consult with your service representative in regard to cleaning of internal parts.
This is particularly effective if accomplished prior to seasons of high humidity. Consult with your
service representative in regard to the cost of cleaning the internal parts of the machine.
Other precautions
Do not place heavy objects on the machine or cause other damage to the machine.
Do not open the front cover, turn off the main power switch, or pull out the power plug during copying.
When lifting or moving the machine, contact your service representative.
When moving the machine, please turn the four adjusters of the paper feeding unit until they reach the floor in
order to stabilize the machine.
Do not touch electrical parts, such as connectors or printed circuit boards. They could be damaged by static
electricity.
Do not attempt to perform any operations not explained in this guide.
Caution
: Use of controls or adjustments or performance of procedures other than those specified herein may
result in hazardous radiation exposure.
Do not look directly at the light from the scanning lamp as it may cause your eyes to feel tired or painful.
This machine comes equipped with an HDD (hard disk drive). Do not attempt to move the machine while the
power is still on. Since any resulting shock or vibration may cause damage to the hard disk, be sure to turn off
the power before attempting to move the machine.
In the event there is a problem with the machine’s HDD (hard disk drive), stored data may be erased. It is
recommended that important data be backed up on a PC or other media. Be also sure to store originals of
important documents separately.
