• Make sure the location is not affected by extreme temperature changes, and
always stays between 59°F and 80.6°F (15°C and 27°C).
• Make sure the relative humidity of the area is between 20% and 80%.
• Keep the machine away from direct sunlight.
• Do not use or store the machine outdoors.
Power Supply
• Do not damage or modify the power cord and power plug. Also do
not place heavy objects on the power cord, pull on it, or extensively
bend it. These actions may cause electrical damage and result in a
fire or electrical shock.
• Do not insert or unplug the power plug with wet hands, as this may
result in electrical shock.
• During electrical storms, disconnect the power cord from the power
outlet. Electrical storms may cause damage to the machine and
result in a fire or electrical shock.
• If dust accumulates around the plug of the power cord when it is
connected to a power outlet, unplug the machine and wipe the plug with
a clean, dry cloth.
• Do not plug the machine into the same circuit with appliances such as
an air conditioner, television or copier. These devices generate an
electrical noise, and may interfere with your machine’s ability.
• Plug the machine into a standard 120 V AC/60 Hz, three-prong grounded outlet. Operate the machine only
from the type of power source indicated on the machine’s label. If you are not sure of the type of power
available, consult your local power company.
• Use only the power cord that came with the machine.
• Unplug the machine in the following conditions:
– When the power cord or plug is damaged or frayed.
– If liquid has spilled into the machine.
– If the machine has been exposed to rain or water.
– If the machine does not operate normally when you have followed the instructions in the guides included
with your machine. Adjust only those controls that are covered by the instructions in the guides since
improper adjustment of other controls may result in damage and will often require extensive work by a
qualified technician to restore the product to normal operation.
– If the machine has been dropped or damaged.
– If the machine exhibits a distinct change in performance, indicating a need for servicing.

Handling
• Do not drop paper clips, staples, or other metal objects inside the
machine. Also do not spill water, liquid or inflammable substances
inside the machine. If these items come into contact with high-voltage
parts inside of the machine, it may result in a fire or electrical shock.
If these items are dropped or spilled in the machine, unplug the
power cord immediately with dry hands. Then, contact your service
representative.
• Do not use any highly flammable spray near the machine. If gas
from a spray comes into contact with the electrical components
inside the machine, it will result in a fire.
• Close the ADF or the platen glass cover gently to avoid catching
your hand. Failing to do so may result in personal injury.
• Do not press down hard on the platen glass cover when using the
platen glass to scan a thick book. This may damage the platen glass
and/or result in personal injury.
• Do not subject the machine to strong physical shock or vibration.
• Unplug the machine before moving it.
• Do not lift the machine by any of its attachments.
• If the machine exhibits a distinct change in performance, this indicates a need
for servicing.
Maintenance
• Do not place the cartridge in fire. Toner powder is flammable.
• Keep the machine clean. Dust accumulation may prevent the machine from operating properly.
• Do not service the machine yourself except as specifically described in this guide. If further
servicing is required, contact your service representative.

minutes. You can also turn off the energy saver function. (→p. 9-4)
• The energy saver function does not activate when the machine is in the following status:
– When printing out copies or other pages
– While a copy job is saved in memory or when the reserve copy or other functions are operating
– When paper jams occur
– When no paper is loaded in the cassette or multi-purpose tray
– When PRESS SET KEYis displayed

NOTE 
						

							2-1
For high-quality copies, we recommend using paper and transparencies recommended by Canon. Some types of
paper available at office supply stores may not be suitable for this machine. If you have any questions about
paper and transparencies, consult your dealer or Canon Customer Relations.
Paper Storage
In order to prevent paper jams, follow the procedure below:
• To prevent moisture buildup, store remaining paper wrapped tightly in its original package. Store paper in a dry
location, out of direct sunlight.
• To prevent curling, store paper flat, not upright.
• After copying, do not leave paper in the multi-purpose tray.
Unacceptable Paper
Do not copy on the following types of copy stock; doing so will result in paper jams.
• Severely curled or wrinkled paper
• Transparencies for full-color copiers or printers
• Paper which has already been copied using a digital full-color copier (Do not copy on the reverse side either.)
• Paper which has been printed on using a thermal transfer printer (Do not copy on the reverse side either.)
• Never attempt to make copies on full-color transparencies. Doing so may result in copier malfunction.
Acceptable Paper
• The printing speed may be slower than usual depending on the paper size, paper type and the number of
sheets you specify.
This is because the safety function works to prevent a failure due to excessive heat.NOTE

•Adjust the slide guides so that there is no space
between the slide guides and the edge of the paper
stack.
5When loading paper other than letter size,
specify the paper size.
