(Note for cleaning the development unit)
If the development unit is cleaned with a cleaner or an air blower
with much developer in the development unit, static electricity
may be accumulated in the unit. In order to prevent against this,
note the following items.
* If metal part is brought into contact with the magnet roller sur-
face when transporting developer or removing foreign material
from the magnet roller, developer may adhere to the magnet
roller surface. Be careful to avoid this when handling the mag-
net roller.
* Remove developer in the development unit as well as devel-
oper attached to the magnet roller as far as possible.
* (When cleaning the development unit with an air blower [duct]) 
Before cleaning with an air duct, remove developer from the
unit as far as possible, and ground the magnet roller rear side
cored bar as shown in the figure below and clean the unit with
an air blower. (Do not pinch the grounding wire with a crocodile
clip connector in order to prevent against damage on the cored
bar.)
