Replacing the Toner Cartridge
6
Close the front cover.
IMPORTANT
If you cannot close the front cover, check if the toner cartridge is installed properly. 
If you try to close the front cover forcefully, this may result in damage to the printer.
Do not leave the front cover open for a long time after installing the toner cartridge.
If the print is too thin even after performing the operation above, replace the toner 
cartridge with a new one.
Replacing Toner Cartridge
Replace the toner cartridge with a new one using the following procedure.
WARNING
Do not throw a used toner cartridge into open flames, as this may cause the 
toner remaining inside the cartridge to ignite, resulting in burns or a fire.
CAUTION
Take care not to allow the toner to come into contact with your hands or 
clothing, as this will dirty 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.
IMPORTANT
Dispose of the packing materials according to local regulations.
Be sure to use only the toner cartridges designed for this printer.
NOTE
For details on handling the toner cartridge, see "Precautions for Handling Toner 
Cartridge," on p. 5-14.
