Question about Ricoh Aficio AP3800C Laser Printer

1 Answer

Have a Ricoh Aficio Cl 4000DN and have replaced the CPU Drum

I am getting a flashing message on my board that reads "CS 307, Power off/on, If error reoccurs call for service.

The manual states I should get the message CALIBRATING for 5 minutes. I can't clear the CS 307 message.

What is this problem?? I already tried reinstalling the drum twice. HELP!!!

You most likely have a defective "yellow" PCU . Try replacing that.
Otherwise you have a high voltage problem

My ricoh aficio code a 990 how to fix them ?


An SC990 is usually an error indicating maintenance is overdue. The only way to verify that is by printing out the SMC report and seeing the subcodes. In the case of this model when is the last time the drum and developer was replaced?

Code error 307 ricoh CL4000DN


sc 307 is a charge bias error having to do with the yellow photoconductor unit (PCU). Replacing the yellow PCU should resolve your problem. If the problem persists even with a new PCU, you will likely need to have either the high voltage supply board or the drum positioning plate replaced.

Thanks for using FixYa!

How can i solve error code sc:302 in ricoh Aficio 2000 copier.


You should have a service technician take a look at your copier. SC302 is a charge roller current error, and it could be caused by a number of things, from a dirty charge roller to a faulty high voltage supply board.

In the meantime, try turning the machine off, unplugging it, and then plugging it back in and turning it on the see if the error message will clear.

On a ricoh aficio 3500n color laser printer getting a replace black cpu error after changing the black cartridge. How do i take care of this?


replace the black pcu(drum unit).
the life of the pcu(s) are 15k each(blk & col) .
the machine will work but copy quality will reduce and the error will be there.
replacing the cartridge has nothing to do with this error.

My printer flashes alert CS 441 off on. Can you tell me what's wrong?


The SC 441 is a color pcu motor lock. One of the waste toner augers is clogged with waste toner not letting the drum turn. The only real fix is to replace the color pcu unit. If you could get the auger and drum out it might be possible to free it up, but you will probably damage the drum in the process.

Ricoh CL 7000 error code SC 387


This Code relates to color gamma error in the Yellow development. Possible causes Low toner density in the Y toner,Toner supply Y mechanism problem( not supplying enough toner),Laser exposure problem, image transfer problem. My suggestion would be to ensure you have toner in the cartridge( but by this time it has depleted the developer), and you will need to replace the development unit and possibly the drum Unit. My best guess would be the development Unit.
