To remove the Dev. unit. 1. Open the right upper cover and front cover. 2. PCU. (☛ 3.11.1) NOTE: Spread paper on a clean flat surface that is free of pins, paper clips, staples, screws or any other metal objects. 3. Loosen [A] (! x1) 4. Rotate bracket [B] left. 5. Development unit [C] NOTE: Pull slowly to avoid scratching or nicking the development roller. 6. Set the development unit on the spread paper. 7. If you are temporarily installing a used development unit for test purposes, perform SP2-220 and 2-802-1 after installation (☛ Chapter 5, “Service Tables)
Replacing the Dev. material. 1. Development unit (☛ 3.12.1) 2. Remove the development roller (☛ 3.12.3) 3. Empty toner [A] 4. Turn drive gear [B] to ensure that no developer remains in the unit or on the developer roller. NOTE: Dispose of the used developer in accordance with local regulations. Work carefully to avoid scratching or nicking the development roller. 5. Pour approximately 1/3 of the developer [C] evenly along the length of the development unit. 6. Rotate the drive gear [D] to work the developer into the unit. Repeat [C] and [D] until all toner is in the unit and level with the edges. 7. Reassemble the development unit 8. Cover the toner entrance hole [A] with a piece of paper. 9. Install the development unit in the machine. 10. Turn on the main power switch, make sure that the machine has warmed up, then perform the TD sensor initial setting using SP 2-801. NOTE: When performing this setting, cover the toner entrance hole with a piece of paper. This prevents used toner falling from the PCU into the development unit during the TD sensor initial setting and interfering with the Vref setting (toner density reference voltage). 11. After performing the TD sensor initial setting, remove the sheet [A] from the development unit.
This is how you replace and reset (calibrate) the new Dev. material.
