Store toner cartridges as described below. Storing toner cartridges in an improper location or environment may
cause problems such as data loss.
● Store unopened until immediately prior to use.
● Do not store toner cartridges upright or upside down.
● Do not store toner cartridges in the following locations:
- Locations exposed to open flames
- Locations exposed to direct sunlight or bright light for five minutes or more
- Locations exposed to excessively salty air
- Locations heavily exposed to corrosive gases (e.g. aerosol sprays or ammonia)
- Very hot and/or humid locations
- Locations subject to dramatic changes in temperature and humidity likely to cause condensation
- Very dusty locations
- Locations within the reach of children
- Locations close to products affected by magnetism (e.g. floppy disks or disk drives)
● Store the packaging material safely for future use. It will be needed for situations such as storing the
machine with the toner cartridges removed.
● Canon reserves the right to reposition, reshape, add, or remove packaging material without notice.
● Store toner cartridges in the following conditions:
- Storage temperature range: 32 - 95 °F (0 - 35 °C)
- Storage humidity range: 35% to 85% RH (relative humidity, condensation-free) *1
*1 Even within the approved storage humidity range, water droplets (condensation) may develop inside the toner
cartridge if the temperatures inside and outside the toner cartridge differ. Condensation will adversely affect the print
quality.
Be careful of counterfeit toner cartridges
● Please be aware that there are counterfeit Canon toner cartridges in the marketplace. Use of counterfeit
toner cartridge 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.

● The toner cartridges may need to be replaced before reaching the average number of sheets that can be
printed depending on the installation environment, paper size to be printed, and original type.
● Automatic calibration may be performed in response to changes in the environment to maintain image
quality. Automatic calibration may also be performed when the power is turned ON and when recovering
from sleep mode. Performing calibration uses the toner cartridges, which may affect their lifetime.
● The lifetime of color toner cartridges may also be affected by black and white printing. When you print large
volumes in black and white, the number of sheets that can be printed for each color toner cartridge may be
reduced.
