1-5-4 Developing section
(1) Detaching and refitting the developing unit
1. Open the top cover.
2. Open the front cover.
3. Remove the developing unit (with toner container).
4. Check or replace the developing unit and
refit all the removed parts.
5. When the developing unit is replaced with a
new one, carry out the following procedure.
6. Perform toner install mode in the service
mode (see page 1-3-12).
When the developer is added during normal replacement, the developer bottle is installed in place of the toner bottle. Then when the F8 mode is initiated from the service mode the developer is added into the developer unit and automatically calibrated. This is only done after the old developer has been cleaned from the DV unit.
The toner bottle contains no developer. The developer is replaced separately and only needs to be changed about every 80,000 pages.
Good Luck and Thnak You for using Fixya.
No, the 450 is just one of those machines that seem to have PCQ no matter what you do. Given light copies, I'd replace the drum for sure and make sure your ID sensor isn't covered with toner. Dust covered optics will also cause light copies on this model.
Remove PCU, remove development unit, remove cover (2 plastic C-clips) remove filter, remove development roller (2 shoulder bolts). Clean roller and empty all developer. Pour in new developer, re-assemble unit. Reinstall drum and Development unit. Place a small piece of paper between the PCU and toner entrance hole to prevent used toner from entering dev. unit during calibration. Perform SP2-801. Remove paper form dev. unit
1. Check that Dev. unit has the lastest seals. 2. replace dev. material. 3. Dump dev. 4. add new dev. material. 5. Hand rotate the dev. unit 10 times. 6. reinstall the dev. unit into machine. 7. cover the toner inlet opening with a piece of paper 8. insert PCU unit. 9. turn the machine on. 10. When machine reaches ready -- enter SP modes and perform SP-2801 (2 times) 11. open the right cover of the machine. Cheat the right cover switch. Examine the drum as it rotates. Afew bands of toner and the ID pattern will be developed on the drum. The drum should be clean -- a slight dusting on the drum is OK. 12. Perform SP-3001 -- ID sensor initial setting. 13. ** Important** remove the PCU unit. Empty the toner from the PCU by sliding the shutter on the bottom of the PCU to the side and tapping the PCU. 14. reinstall the PCU. 15. Run test copies.
Hello sir; Just follow the steps;
1, dump entire dv use vaccunm cleaner to cleanup don't leave any dv inside.
2, thorughly clean out magnet roller by rubbing alcohal.
3, pour in new dv evenly.

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.
u check drum,ibt belt,2nt btr roller and fuser life... then do full service, then calibrate ur fiery also.. first u check developer bios plate.. if its have more dust print comes like that.. all the best..
