This chapter explains how to clean the machine, replace the toner cartridge, and repack and 
transport the machine.
Periodic Cleaning
Your machine requires little periodic maintenance. This section describes the 
necessary cleaning procedures for your machine.
CAUTION
•When cleaning the machines exterior or the platen glass, be sure to disconnect 
the power cord before cleaning the machine.
•Do not use tissue paper, paper towels, or similar materials for cleaning; they can 
stick to the components or generate static charges.
Use a soft cloth to avoid scratching the components.
•Never use volatile liquids such as thinner, benzene, acetone, or any other 
chemical cleaner to clean the interior of the machine; these can damage the 
machines components.
Cleaning the Exterior
Wipe the machines exterior with a clean, soft, lint-free cloth moistened with water 
or diluted dishwashing detergent solution.

When to Replace the Cartridge
The cartridge is a consumable item and should be replaced when the toner runs 
out.
If white streaks or light bands appear on the printouts, the toner is running low.
NOTE
Before handling the cartridge, see the precautions in Handling and Storing the 
Cartridge, on p. 8-5.
1Remove the cartridge from the machine.
2Rock the cartridge 5 or 6 times to distribute the toner evenly.

3Reinstall the cartridge in the machine.
4Make a few test copies.
●If the copies appear normal:
You can keep using the cartridge. However, a new one will be needed soon.
●If white streaks or light bands are still present:
❑
Replace the cartridge with a new one. 
For details on how to replace the cartridge, see Replacing the Cartridge, on p. 
8-13.
Print Yield
This section describes the approximate number of printouts that can be made per 
cartridge.
Approximate Print Yield
Canon Cartridge X25: Approx. 2,500 printouts (A4 at 4% dot coverage*).
* The term A4 at 4% dot coverage denotes a document on which the area covered 
with toner is 4% of the total area of an A4-size sheet.
•The actual number of printouts that can be made per cartridge depends in part on 
the exposure setting, room temperature, and humidity.
•If you print a large number of documents which contain heavy print or many 
photographs, toner consumption will increase, and white streaks will appear on 
printouts sooner than indicated above. Toner consumption will also increase if you 
print with the platen glass cover left open.
•If you print small size documents or documents with less dot coverage, you may 
be able to print more sheets of paper than indicated above. However, dark bands 
might appear on printouts if you keep using the same cartridge for an extended 
period of time.

Handling and Storing the Cartridge
This section describes the precautions to ensure optimum copy quality.
Handling Precautions
WARNING
•Do not throw the cartridge into open flames, as this may cause the toner to 
ignite and result in burns or a fire.
•The cartridge emits low level magnetic flux. If you use a cardiac pacemaker and 
feel abnormalities, please move away from the cartridge, and consult a 
physician.
IMPORTANT
Never attempt to disassemble the cartridge or open the drum protective shutter.
NOTE
•If the machine is brought from the cold outdoors into a warm room, or if the room is 
rapidly heated, condensation may form inside the machine. 
This can adversely effect the quality of your printouts (e.g., copies are completely black). 
When the machine is exposed to such conditions, allow at least 2 hours for the machine 
to adjust to room temperature before attempting to use it.
•When handling the cartridge, take care not to allow the toner on the jammed paper to 
come into contact with your hands or clothing. If they become dirty, wash them 
immediately with cold water. Washing with warm water will set the toner, and make it 
impossible to remove the toner stains.
•Always hold the cartridge as shown so that the side with the instructions (A) faces up. Do 
not forcefully move or push the drum protective shutter (B) in any way.
Storage Precautions
WARNING
Do not store cartridges or copy paper in places exposed to open flames, as this 
may cause the toner or copy paper to ignite, resulting in burns or a fire.

CAUTION
Keep cartridges and other consumables out of the reach of children. If the 
contents of these items are ingested, consult a physician immediately.
IMPORTANT
•Place the cartridge in its protective bag so that the side with the written instructions faces 
up. Then, place the bagged cartridge into its shipping box. Store the unused cartridge out 
of direct sunlight.
•For partially used/opened cartridges, place the cartridge in its protective bag so that the 
side with the written instructions faces up. Then place the bagged cartridge into its 
shipping box and store it away from direct sunlight.
•Avoid storing the cartridge in front of heaters and humidifiers, etc. Store it in a location 
where the temperature does not exceed 104°F (40°C). 
•The recommended storage conditions are as follows:
- Temperature: 32°F to 95°F (0°C to 35°C)
- Relative Humidity: 35% to 85%
•Be sure to remove the toner cartridge from the machine when disposing of the machine.
•Do not stand the cartridge on end or turn it upside down. 
Storing Partially Used Cartridges
If you remove a cartridge from the machine, store the cartridge as described below. 
Place the cartridge in its protective bag so that the side with the written instructions 
faces up. Then, place the cartridge into its shipping box. Be sure to securely close 
the lid of the shipping box.
If you do not have the protective bag or shipping box for the cartridge, store the 
cartridge in a dark location. 
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 
landfill waste. Complete details concerning this program are 
enclosed in each PC Cartridge box.

The Clean Earth Campaign
THE CANON CARTRIDGE RECYCLING PROGRAM
The Canon Cartridge Recycling Program fulfills the first initiative of Canons Clean 
Earth Campaign, which supports four critical environmental areas:
•Recycling in the Workplace
•Conserving Environmental Resources
•Scientific 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 National 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 millions 
of cartridges that otherwise would have been discarded into landfills or similar 
facilities. Instead, this rapidly growing program returns used cartridges to the 
manufacturing process, thus conserving an array of resources.
Becoming a part of this worthwhile program is easy. When your cartridge is of no 
further use, simply follow the instructions detailed for U.S. or Canadian residents. 
We appreciate your support of The Canon Cartridge Recycling Program. 
Working together we can make a significant contribution to a cleaner planet.
•Cartridges collected through this program are not refilled.
•You are not entitled to a tax deduction or rebate for the return of empty cartridges.
•This program may be modified or discontinued without notice.
