10. Turn the tool clockwise (approximately 5 times) until the toner covers the whole area of the
development roller [C].
NOTE 4: If the toner does not cover the whole area of the development roller, redo step 8 to 10.
If you see lines on the roller after doing this step, turn the gear counter-clockwise about 1/4
turn (10 mm). Then, turn the gear clockwise again 2 full turns.
NOTE 5: DO NOT turn the gear in the opposite direction while the toner does not cover still the whole
area of the development unit because toner dropping may occur.
Important note about the development roller cap:
When you install development units from June 2004 production onward, remove the gear cap before you
turn the roller with the special tool. Also, after turning the roller, put the cap back on the roller
The shape of the cap was changed, and the diameter was increased from 13mm to 15mm. This
was done to make it easier to install the development unit (The new gear slides onto the rail
easier).
