The cartridge is a consumable item and should be replaced when the toner runs out.
The following guidelines will help you to determine when to replace the cartridge.
If white streaks or light bands
are still present
If the copies appear normal
Remove the cartridge from the machine.
Always hold the cartridge as shown so
that the side with the written instructions
faces upward. Do not forcefully move or
push the protection shutter of the drum in
any way.
Rock the cartridge five or six times to
distribute the toner evenly.
Re-install the cartridge in the machine.
Then, make a few test copies.
If white streaks or light bands
are displayed on copies, the
toner in the cartridge is running
low.
You can use the cartridge,
however, a new one will be
needed soon. Replace the cartridge with a
new one. (
