Install a new toner cartridge in the image
drum cartridge.
Note
• Although it is possible to reinstall the toner cartridge
that are currently in use, we recommend using a new
toner cartridge for the following reasons.
- Print quality may deteriorate, if more than a year
has passed since the toner cartridge was
opened.
- New image drum cartridges are empty. Once
you have installed a toner cartridge, the new
image drum will fill with toner from that toner
cartridge. Therefore, if you install a toner
cartridge that has only a little toner, the message
[Toner Empty] may appear immediately.
- If you reinstall a toner cartridge currently in use,
the indicator which shows the amount of
remaining toner will be inaccurate.
(1) Remove the new toner cartridge from its
packaging.
Note
• Make sure that the color of the new toner cartridge is
correct.
(2) Gently shake it up and down and side to
side several times.
(3) Lay the toner cartridge flat, and gently
remove the tape.
(4) Make sure that the label color of the toner
cartridge matches the label color of the
image drum cartridge.
(5) Remove the toner cover from the image
drum cartridge.
