Before you begin this procedure you must have an empty developer bottle identical to the one installed in the machine.

The developer does not drain if the developer counter is reset before you try to drain the developer. Always drain the developer first, and then reset the developer counter.

  1. Switch the machine off.
  2. Open the front doors.
  3. Before replacing the developer, you must clean the doctor blade and the development roller. (Cleaning Doctor Blade, Development Roller Cleaning)
  4. Set hole [A] of the toner bottle on the boss [B].
  5. Push the bottle in until you hear it click.
  6. With the front doors still open, turn the machine on.

  7. Enter the SP mode and do SP3022-001 to start draining the developer.

    • The developer requires about 150 sec. to drain completely.
    • If the operation fails, the machine will alert you with a message. Do SP3023-001 to check the result, and then repeat from Step 3.

  8. Turn the machine off after the machine alerts you when the operation is finished.
  9. Remove the bottle, and then re-attach its seal to prevent spillage.
  10. Go into the SP mode and reset the developer counter with SP7-622-003.
