							CHAPTER
Periodic Cleaning8-1
8Maintenance
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.
•For the MF5750/MF5770 models, print any received faxes stored in the memory 
before disconnecting the power cord, since the documents in memory are 
backed up only for about 3 minutes.
•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.

Cleaning the Scanning Area
Wipe the scanning area (shaded area) with a clean, soft, lint-free cloth moistened 
with water, then wipe with a clean, soft, dry, lint-free cloth.
Cleaning the ADF Area
Black lines may appear in copies when the ADF is used to feed documents.
This is caused by paste, ink, correction fluid, or other foreign matters in the read 
area of the platen glass (shaded area). Use a clean soft cloth to wipe the read area 
clean. Take particular care to clean at the locations where the black lines are 
appearing on copies.
If you have trouble getting the glass clean, wipe with a cloth moistened with water 
or a mild neutral detergent, and then wipe the glass dry with another cloth.

IMPORTANT
•Paste, ink, correction fluid, and other foreign matter can soil the platen glass when you 
send a document through the ADF while the paste, ink, or correction fluid on the 
document is still wet. This is what causes black lines on copies. Whenever you load a 
document in the ADF, always check to make sure that any paste, ink, or correction fluid 
that is on the document is completely dry.
•When cleaning the read area of the platen glass, take care not to damage the white roller 
located on the center of the ADF.

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. 8-6.
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. 
8-14.
Print Yield
This section describes the approximate number of printouts that can be made per 
cartridge.
Approximate Print Yield
Canon genuine Cartridge X25: Approx. 2,500 printouts (A4 at 5% dot coverage*).
* The term “A4 at 5% dot coverage” denotes a document on which the area covered 
with toner is 5% 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.
