Replacing the Toner Cartridge
Pull out the seal slowly, otherwise the scattered toner may soil your clothes, etc.
Pull out the seal completely, otherwise the print error may occur.
Pulling the seal upwards or downwards may break the seal. If the seal could break
inside the toner cartridge and cannot be removed completely, the toner cartridge
may not be used.
Ensure the seal is pulled out completely from the toner cartridge because the toner
may scatter and printing quality may deteriorate.
Throw away the seal after removing it from the toner cartridge.
Turn the toner cartridge in the direction of the arrow.
Turn the toner cartridge fully until it locks into place.
