2) Insert the drum rotating tool [1] that comes with the unit into the slit [3]
in the drum shaft [2]. While keeping the drum in place so that it will not
rotate counterclockwise, insert a screwdriver into the center opening [4]
in the drum rotating tool to remove the drum fixing screw.

If the drum is let to rotate counterclockwise, the cleaning blade will not come
into contact with the drum correctly, leading to poor cleaning. Thus, be sure
to fix the drum in place first before removing the drum fixing screw to avoid
the problem.
MEMO:
If the hopper assembly is released but not removed, be sure to open the right
cover (upper) and the right cover (lower) so that there will be space.
3) Unlock the fixing feeding unit release lever [1], and slide out the fixing
feeding unit [2].
