MX-7001N  DEVELOPING SECTION  L – 5

* If metal part is brought into contact with the magnet roller

surface 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 magnet roller.

* Remove developer in the development unit as well as

developer 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.)

6)

Tilt the developing unit (CL) (H) so that developer is moved to
the MG roller side.

7)

Attach the cover (I) to the pawl of the section (J), and lower the
magnet roller side with the pawl at the section (J) as the center
of rotation.
(In order to prevent developer from attaching to the magnet.)
* When installing the cover, be sure to engage the pawl with

the boss.

* If developer is attached to the magnet on the rear side of the

cover, wipe and clean it with cloth.

* Do not put the magnet section near developer.

(In order to prevent developer from attaching to the magnet.)

* After supplying developer, do not tilt the development unit.
