 Handling   Toner  Cartridges 
 Note the following when handling the toner cartridge. 
 
    CAUTION  
 Do not place the toner cartridge in fi  re. 
 This may cause toner remaining inside the cartridge to ignite and 
result in burns. 
 If toner leaks from the toner cartridge 
 Be careful not to inhale the toner or allow it to come into direct 
contact with your skin. If the toner comes into contact with your skin, 
wash with soap. If the skin becomes irritated or you inhale the toner, 
consult a physician immediately. 
 When removing a toner cartridge 
 Make sure to remove it carefully. If not removed with care, the toner 
powder may scatter and come in contact with your eyes and mouth. If 
toner gets into your eyes or mouth, wash them immediately with cold 
water and consult a physician. 
 Keep the toner cartridge away from small children. 
 If the toner or other parts are ingested, consult a physician 
immediately. 
 Do not disassemble the toner cartridge 
 The toner may scatter and get into your eyes or mouth. If toner gets 
into your eyes or mouth, wash them immediately with cold water and 
consult a physician.   
      IMPORTANT  
 Handling toner cartridges 
 Keep the toner cartridge away from computer screens, disk drives, 
and fl oppy disks. They may be damaged by magnet which is in 
inside of the toner cartridge. 
 Avoid locations subject to high temperature, high humidity, or 
rapid changes in temperature. 
 Do not expose the toner cartridge to direct sunlight or bright light 
for more than fi ve minutes. 
 Store the toner cartridge in its protective bag. Do not open the bag 
until you are ready to install the toner cartridge in the machine. 
 Keep the protective bag for the toner cartridge. They are required 
when transporting the machine such as during relocation. 
 Do not store the toner cartridge in a salty atmosphere or where 
there are corrosive gases such as from aerosol sprays. 
 Do not remove the toner cartridge from the machine unnecessarily. 
 Print quality may deteriorate if the drum surface is exposed to light 
or is damaged. 
 Always hold the toner cartridge by its handle to avoid touching the 
drum. 
 Do not place the toner cartridge in an upright or an upside down 
position. If the toner is kept upright or upside down, the toner 
will solidify and may not return to its original condition even if it is 
shaken. 
 When disposing of a used toner cartridge, place the toner container 
into its protective bag to prevent the toner from scattering, and 
then dispose of the toner cartridge according to local regulations. 
 Be careful of counterfeit toner cartridges 
   Please be aware that there are counterfeit Canon toner cartridges in 
the marketplace. 
   Use of counterfeit toner cartridges may result in poor print quality or  machine performance. 
   Canon is not responsible for any malfunction, accident or damage  caused by the use of counterfeit toner cartridge.

   Recycling  Used  Cartridges 
  
Canon has instituted a worldwide recycling program for cartridges called "The Clean Earth Campaign". This program 
preserves precious natural resources by utilizing a variety of materials found in the used cartridges
that are of no further use, to remanufacture new cartridges which, at the same time, keeps the environment cleaner by 
reducing landfi ll waste.
Complete details concerning this program are enclosed in each Cartridge box.
The Clean Earth Campaign
THE Canon CARTRIDGE RECYCLING PROGRAM
The Canon Cartridge Recycling Program fulfi  lls the fi rst initiative of Canon's Clean Earth Campaign, which
supports four critical environmental areas:
Recycling in the Workplace
Conserving Environmental Resources
Scientifi  c Research and Education
Encouraging Outdoors Appreciation
The remaining "Clean Earth" initiatives are supported in the U.S. through sponsorships of the National Park Foundation, the Nat ional 
Wildlife Federation, and The Nature Conservancy and in Canada through donations to the World Wildlife Fund Canada and The 
Nature Conservancy of Canada.
Since its inception, The Canon Cartridge Recycling Program has collected huge amount of cartridges that otherwise would have 
been discarded into landfi  lls or similar facilities. 
Instead, this rapidly growing program returns used cartridges to the manufacturing process, thus conserving an array of resourc es.
Becoming a part of this worthwhile program is easy. When your cartridge is of no further use, simply follow the instructions de tailed 
for U.S. or Canadian residents.
We appreciate your support of The Canon Cartridge Recycling Program.
Working together we can make a signifi  cant contribution to a cleaner planet.
Cartridges collected through this program are not refi  lled.
You are not entitled to a tax deduction or rebate for the return of empty cartridges.
This program may be modifi  ed or discontinued without notice.
