SOURCE: Ricoh CL3000 Laser Replace Waste toner

Couple of things to try: - If you just emptied the waste cartridge then you have to take the bottle back out and clean the insides as well. The sensor sees the toner on the walls and still thinks it?s full. FYI as typical the manufacturer recommends replacing the bottle with a brand new one. - If not that then you may have toner covering the optical sensor. Try blowing the area where the waste bottle attaches to the printer with canned air. Let us know if you have any other questions and please don?t forget to rate this post.

SOURCE: Ricoh fuser oil replace message

That is not a good idea. The oil is kept track of by counting pages, not by a sensor that measures the oil level. The oil runs out and the machine can't tell and now you have ruined the fuser. Which cost a lot more than the oil tank.

Manufacture specific toner is usually the problem. Replace toner with manufacturer cartridge, or replace because it is bad. Take back to the store you bought it from.

Replace black PCU ricoh aficio cl3000


To replace the black PCU:

- Turn the printer off.
- Open the cover on the right side (as you're looking at the front of the printer).
- There are two green levers, one toward the front of the printer and one toward the back -- pull these out and lift the cover that they're holding all the way up (it should stay in place).
- Remove the black PCU by pinching the green lever and sliding the unit straight out.

- Take the new PCU out of the box, take off the tape around it and remove the cover on top of the unit.
- Align the new PCU along the rails the same way the old one was aligned (using the green arrow) and slowly slide it in. As you slide it in it will slide out of the bottom cover -- throw that cover away.
- Lower the PCU cover and slide the levers into place.
- Close the side door.
- Turn the printer on.

I have a Gestetner DSc38u and when I print colour I get a 'red'/'pink' line about an inch from the top of each page. Any suggestions?


If the line is only red or pink, it is most likely caused by the magenta PCU. Replace this PCU and your problem will go away.

Occasionally the magenta developer unit can cause a red or pink line, but the problem is more than likely from your magenta PCU. The PCU is easy to replace, and instructions will come in the box if you order an OEM replacement unit.

Black Lines running down the right side outside of the print area


It may be the fuser. Take it out and inspect the roller on it:

  1. Switch off the device, disconnect the mains plug and wait for 30 minutes before continuing.
  2. Ensure that the bypass tray is closed, or you will not be able to open the front cover.
  3. Open the front cover by pressing the release buttons as shown.
  4. Pull the front cover down towards you.
  5. Disconnect the green plug - squeeze the sides of the plug and pull.
  6. Push the left and right levers outward to unlock the unit.
  7. Pull the unit towards you as shown and lift it clear of the device.
  8. Check the roller for wear marks, If so replace it.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

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.
