Indicates a warning concerning operations that may lead to 

death or injury to persons if not performed correctly. To use the 

machine safely, always pay attention to these warnings.

Indicates a caution concerning operations that may lead to injury 

to persons if not performed correctly. To use the machine safely, 

always pay attention to these cautions.

-  Do not install the printer in a location near alcohol, paint thinner, or other 

flammable substances. If flammable substances come into contact with 

electrical parts inside the printer, this may result in a fire or electrical 

shock.

-  Do not place the following items on the printer.

- Necklaces and other metal objects

- Cups, vases, flowerpots, and other containers filled with water or 

liquids

If these items come into contact with a high-voltage area inside the 

printer, this may result in a fire or electrical shock. 

If these items are dropped or spilled inside the printer, immediately turn 

OFF the power switch (1) and disconnect the interface cables if they are 

connected (2). Then, unplug the power plug from the AC power outlet (3) 

and contact your local authorized Canon dealer.

-  When installing or removing the optional accessories, be sure to turn the 

printer OFF, unplug the power plug, and then disconnect all the interface 

cables and power cord from the printer. Otherwise, the power cord or 

interface cables may be damaged, resulting in a fire or electrical shock.

-  Do not damage or modify the power cord. Also, do not place heavy 

objects on the power cord or pull on or excessively bend it, as this can 

cause electrical damage, resulting in fire or electrical shock.

-  Keep the power cord away from all heat sources. Failure to do so can 

cause the power cord insulation to melt, resulting in a fire or electrical 

shock.

-  The power cord should not be taut, as this may lead to a loose 

connection and cause overheating, which could result in a fire.

-  The power cord may become damaged if it is stepped on, fixed with 

staples, or if heavy objects are placed on it. Continued use of a 

damaged power cord can lead to an accident, such as a fire or electrical 

shock.

-  Do not plug or unplug the power plug with wet hands, as this can result 

in electrical shock.

-  Do not plug the power cord into a multi-plug power strip, as this can 

result in a fire or electrical shock.

-  Do not bundle up or tie up the power cord in a knot, as this can result in 

a fire or electrical shock.

-  Insert the power plug completely in the  

AC power outlet. Failure to do 

so can result in a fire or electrical shock.

-  If excessive stress is applied to the connection part of the power cord, it 

may damage the power cord or the wires inside the machine may 

disconnect. This could result in a fire. Avoid the following situations:

- Connecting and disconnecting the power cord frequently.

- Tripping over the power cord.

- The power cord is bent near the connection part, and continuous stress 

is being applied to the power outlet or the connection part.

- Applying a shock to the power connector.

-  Do not use power cords other than the one provided, as this can result in 

a fire or electrical shock.

-  As a general rule, do not use extension cords. Using an extension cord 

may result in a fire or electrical shock.

-  Do not install the printer in unstable locations, such as on unsteady 

platforms or inclined floors, or in locations subject to excessive 

vibrations, as this may cause the printer to fall or tip over, resulting in 

personal injury.

-  The ventilation slots are provided for proper ventilation of working parts 

inside the printer. Never place the printer on a soft surface, such as a 

bed, sofa, or rug. Blocking the slots can cause the printer to overheat, 

resulting in a fire.

-  Do not install the printer in the following locations, as this may result in a 

fire or electrical shock.

- A damp or dusty location

- A location exposed to smoke and steam, such as near a cookery or 

humidifier

- A location exposed to rain or snow

- A location near a water faucet or water

- A location exposed to direct sunlight

- A location subject to high temperatures

- A location near open flames

-  When installing the printer, gently lower the printer to the installation site 

so as not to catch your hands between the printer and the floor or 

between the printer and other equipment, as this may result in personal 

injury.

-  When connecting the interface cable, connect it properly by following the 

instructions in the e-Manual. If not connected properly, this may result in 

malfunction or electrical shock.

-  Be careful when handling the main board or the ROM. Touching the main 

board or the sharp parts such as the edges of the ROM may result in 

personal injury.

 

-  When moving the printer, follow the instructions in the e-Manual to hold it 

correctly. Failure to do so may cause you to drop the printer, resulting in 

personal injury.

-  Do not use a power supply voltage other than that listed herein, as this 

may result in a fire or electrical shock.

-  Always grasp the power plug when unplugging the power plug. Do not 

pull on the power cord, as this may expose the core wire of the power 

cord or damage the cord insulation, causing electricity to leak, resulting 

in a fire or electrical shock.

-  Leave sufficient space around the power plug so that it can be 

unplugged easily. If objects are placed around the power plug, you may 

be unable to unplug it in an emergency.

To avoid the risk of personal injury or damage to the printer, and for legal 

information, make sure to read the "Legal Notices" and "Important Safety 

Instructions" in the e-Manual included on the accompanying User Manual 

CD-ROM carefully before using the printer.

See the e-Manual.
