Error Message: Replace Black PCU

I have an error message that reads: Replace Black PCU. What is a Black PCU, where is is, and how do I go about replacing? The printer originally quit working, when this message appeared, but once I turned the printer off and restarted it is now printing, but the message is still there.

Re: 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.

How do i fix the error message set pcu correctly on my ricoh aficio sp c811dn

Turn the machine off. Open the access door and remove the cyan photoconductor unit. Check the contact pins are straight and undamaged. Gently reinsert the unit. Turn the power back on. If the machine still does not recognise the pcu is inserted it is probably damaged and needs replacing. How many copies/prints has your machine done?

I have a ricoh c410dn and it has an sc364 error.

sc364 is a black toner density error. Typically, replacing the black PCU will get rid of the error message.

Error message: replace pcu

I believe its asking you to change the photo conductor unit. From what I can tell there are 2. Theres a black photo conductor and a color photo conductor. If its not telling you which one you should be able to print a supplies status page and you can see which one needs to be replaced. I'm not totally familiar with the machine but the PCU's should be located in the cartridge area. I just checked out our supply catalog and you should be able to order them from any office supply store or Ricoh dealer. Just a heads up..from what I'm looking at the black pcu is pretty reasonable, but the color one is $300 plus! For your sake I hope its the black one that needs replacement! You should be able to verify the error message in your user manual and more than likely find the part number for ordering.
