4. Pour about half a pack of developer [E] into the development unit. Then
rotate the two outer gears [F] and [G] as shown to distribute the developer
evenly. Then pour in all the remaining developer and rotate the gears again.
NOTE: Do not rotate the gears in the other direction, or developer will spill
out.
5. Remount the toner supply unit on the development unit (2 screws) and
reconnect the connector.
NOTE: Make sure that the positioning rib [H] sits in the groove [I].
6. Install the development unit in the copier (1 knob screw and 1 connector).
7. Turn on the main switch, then perform the TD sensor initial setting for new
developer using SP2-214.
CAUTION
Never make any copy with the new developer before completing the TD
sensor initial setting (SP2-214). Otherwise toner density control will be
abnormal.
