5. Remove the developer roller (fig.5). Vacuum or
use compressed air to remove all remaining toner

sealing blade when cleaning the residual toner.

6. The developer roller felts are
attached to the doctor blade (Fig. 6). It
is not recommended that you remove
the doctor blade and damage the felts.
Simply clean the leading edge of the
blade with a lint free wipe.

7. Reassemble the cartridge in reverse order. After reinstalling the developer roller
make sure that the small protrusion on the plastic plate on the gear train side is firmly
back in the recessed area on the side of the hopper. Fill the hopper with toner (Oasis
part #BRTN10210) and install the fill cap. Install a cartridge cover (Oasis part #
BRCP10), this will prevent leaking and damage to the developer roller during
shipping (Fig. 7).
