Ricoh MPc4502 PCU

[Llama God]

Hi,

I've hunted high and low for a definitive answer to this but have so far drawn a blank.

Does anybody know whether any of the previous PCUs (B2242042 or D0292256) will go into the new MPc4502 or 5502 machines?

Also, has anybody successfully used the B2242042 type PCUs in the MPc4000 type machines?

Ta in advance,

Chris

We've been using the D029 2256 pcu in the MP C4502/5502 range with out any problems. Have to take the usual steps, file corner off, swap wires over then snap the locating lug off the base plate in the back of the machine. A bit of work but save a $1000 every time you change the CMY. Of course you have to use the correct K unit as the shape is completely different.
Never tried putting a MP C4500 pcu in a MP C4000

So you use the D0292256 PCU to replace the colour PCUs in the new models? We haven't changed a PCU yet, somehow!

Re: Ricoh MPc4502 PCU

Ive not as yet had to replace a MPC3001 PCU and we have a few on 500k now.

The MPC2500 Black drum B224-2042 Fits the MPC2800 COL slot without changing the wires over but still needs the connector corner removing Btw! and its cheaper than the 2800 blk PCU

Re: Ricoh MPc4502 PCU

Thanks for the great cheat sheet. I added some procedure photos that I cribbed from other threads (sorry OP's, I'll try and hunt down your names and give you credit). I didn't have a photo of cutting the pin in the rear, so if someone has one or could take one then please add it to this pdf and clean it up as you see fit.

*FYI, I edited it online with "PDFescape".

Great addition. I'm not sure I have done the base plate mod before. What does that consist of?

If you remove drum units from the copier and look into the back of the cavity you will see the locating lugs on the rear of the plate that holds the PCU.

This is the lug you have to remove.

I built a jig that quickly snaps the lug off and I'll post a picture as soon as I find out which tech borrowed it from the workshop and is to slack to return it.

Or what Bantams already said! I should pay more attention in class.

Nice edit, and very cool site! Thanks for that. It'll come in very handy.
Now THIS is one of those threads that just keeps getting better!

Thanks everyone for the very helpful info!

My lug removing jig suddenly re-appeared.

There is a slot on the end of the rod that the metal bracket that holds the lug slips into. Swing the handle from side to side several times and the lug snaps neatly off. All over and done with in seconds.

I use very strong snips. You are not getting my whisky, it's mine and I need it.

And I do mean need.
