SOURCE: Ricoh Aficio AP3800c--message to replace black

Are you sure you replaced the PCU and not the development unit? When you replace a PCU on the 3800, there is a fuse or tab that tells the copier it has a new PCU. If you put a brand new black PCU in the machine and it didn't recognize it, chances are that PCU was damaged. You can either keep running the machine and ignore the message, or try to replace the PCU with a new one again.

SOURCE: replace black PCU ricoh aficio

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.

My Ricoh Aficio SPC811DN printer keeps asking me to replace my PCU colour all the colour carteridges are over half full what do i have to rplace

The PCU is the drum unit. There is one for each colour (C,M,Y & K). Each PCU has a 'life' and the machine will ask you to replace it when it has reached the end of its expected life. The PCU life has nothing to do with the amount of toner that you have in the cartridges and they need to be changed independantly.

I have some ricoh aficio 1224c with errors c481

Transfer belt mark detection error
• The main motor is operating; and
the lock signal is detected. → The
belt mark sensor signal does not
change for 120 milliseconds.
• Defective main motor
• Image transfer belt out of position
• Belt mark blurred or absent

I would remove the pcu unit (3 screws)and check the transfer assy belt mark and clean the sensor that reads the belt mark. Worst case senerio is replaceing the entire pcu unit.

Hi.when i m switch on the Ricoh 3310L Fax,the message is coming as shown below "time to change PCU"

Order a new PCU from Ricoh. Power off the machine and replace the pcu.
If you try and cheat it it will run for a short while and then lock-up breaking some gears. Cheeper just to order a pcu. Check Ebay, i see alot of Ricoh supplies there.

Error Message: Replace Black PCU

I'm not sure how to obtain one, but "Black PCU" stands for Black Photoconductor Unit, and according to a manual for a different Ricoh printer model, it should be fairly simple to replace if you can find one.
