One of the most common reasons for a Lanier 5222 or 5227 to make dark copies is a problem with the drum unit or developer. Fortunately on those machines, the drum unit and developer are all self-contained in one easily-replacable unit, called the PCU (photoconductor).
If you don't have a new PCU handy, you can order one from the same company you get your toner from. The PCU should generally be replaced every 60,000 copies, but sometimes it may need to be replaced sooner (especially if you run a lot of dark copies or make a lot of copies of images) and it can often run longer than 60,000.
Replacing the PCU is easy -- it sits right next to the toner bottle, and all you have to do is slide the old PCU out and slide the new PCU in (once you remove all of the tape and other trappings from it). Instructions will be included in the box with the new PCU.
Please rate the effectiveness of this solution. Thank you!
THE MAINTENANCE PROMPT COULD BE TURNED OFF BUT THAT IS AGAINST THE MANUFACTUREERS RECOMENDATION. THE PCU
WOULD LAST A LITTLE LONGER BUT IT WILL START DUMPING TONER AND DEVELOPER IN TRAY1 IF IT ISNT ALREADY THAT JUST ADDS TO THE CLEANUP TIME AND COST THE PCU WAS DESIGNED TO MAKE 60,000 PAGES.
Do you mean the photoconductor unit? To replace the photoconductor (PCU), open the front cover and the right side covers (the duplex door and the main side door). The PCU sits to the right of the toner bottle -- it is a black unit that has the blue cylindrical drum facing the right side of the copier.
On the upper left side of this unit is a ridged tab. Push this tab in and slide the PCU all the way out of the machine. Open the box with the new PCU and remove all of the tape and paper, then slide the new PCU in where the old one came out of. When you shut all of the covers, the copier will recognize the new PCU.
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.
You are more right than you know, the reason for the kit is for the reasons you said. When you change the kit all 3 colors are new and thereby not 3 service calls and 1 upset customer.
The kit is far cheaper and keep any "good PCUs" in the original package.
The black PCU is the most important one. Buying the different maint. kits saves $$$ as opposed to peicemeal.
You can put one color PCU in at a time if you wish.
-Carl, please let me know if this helps.
Most of the time when I find this happening on a printer, not just Ricoh's it turns out to be the PCU (photo conductor unit). The color PCU is one unit and the black is a seperate unit. Hope this helps.
