Are colour pcus interchangable on mpc 3500s?

It is also really easy to swap the wiring harness instead of filing down the connector. The cleaning unit comes off with two screws and the harness is directly underneath a foam strip. Also, I've used the printer version drum unit and that works fine in the copier version, however i have not been able to get the developer to work. It keeps telling me "Photoconductor set incorrectly". Ive tried swapping the TD sensor and harness from the copier version developer, and set the machine to initialize the developer on start up, but to no avail. Has anyone been able to get this to work?

you can actually, quite easily, take the loom out if you want to keep things neat.

LOL I started my wire loom and connector collection today.

It will be interesting to see if they raise the price of black drum unit if they ever catch on to what's happening.

No problems experienced here using the modified black drum unit with the correct developer unit in a colour drum slot.

Another thing to consider is that the printer fuser is a fraction of the cost of aMFD fuser.
I've yet to try it to see if the SPC811 printer fuser works in the MPC2500 MFD but at least you could buy in a printer fuser for parts only, to use on an MFD

You say that one thing to try is swapping fusers from machine to machine, however this maybe ok, but one thing to consider is the heat tempreturte at which the toner melts to the page. Due to paper through put speed (ppm) variance machines will run at a higher or lower temp. Seen in particularly the HP4000 range which are standard laser jet mono printers. The 4200, 4300, 4250/4350 and Mfp version have seperate fusers, some are interchangeable but not all. With regards to the drums I know for a fact from remanufacturing this range there is no difference electrial contact between the OPC/drum is the same as it is in the black. And will have no reflection, its purely a cost thing for ricoh, or whoever i know canon do something similar.

Hope this helps

True but the 811 prints at 40ppm. Even with the same thermistors, the controller will control the temperature with regards to the speed.

Do you mean the SC811? Your right, it does, but this probably is reflected in the toner, its a very simialr machine to the 3800/7000/7100 range and these all have developments in toner. They use a very similar Chemical Toner with changes to the melting points of the wax shell.

Good evening, no need to carry more than the pcu - k, 2 routes to fit for colour status.

1 file the connector down, but beware of too much pressure on locating pin, as this leads to a poor pcu fit when reinstalled, suggest unscrewing cnnector on rear of pu and then filing down the connector.

2 swap wiring harness, takes about two minutes and saves any locating problems. ( remove pcu cleaning unit (2 screws), remove foam strip(this will refix easily). Unscrew connector, and repeat on new unit.

From recent experience the second method is far more reliable.

Good luck

Bottom line is that the industry as a whole wants the world to believe that color is expensive to manufacture, and therefore should be expensive to maintain (as well as various parts for b/w machines).

This may have been true at one point. But as you all are proving here, is not true today.

But as long as the manufacturers think they have the wool pulled over the public's eyes, this will continue to be the case. And yes they think they have the wool pulled over OUR eyes also. So, why not price gouge us service folks as well?

Will be interesting to watch when the general public catches on to this.
(Hopefully not too long, as it's becoming more and more obvious.)

Oh, and P.S.- To all the manufacturers: You can take your high priced
hard drives, and memory and shove em where the sun don't shine.

(I could go on and on, but I'll stop. Almost fell off the edge there! )

I feel the real ball buster is the price jump from the previous two color models. With a drum unit in the neighborhood price of $50 compared to $90 or $350 per unit, you now have to price your maintenance that much higher for the same amount of copies. I could completely understand a higher cost for a higher yield part, but for a price doubled or higher it really crushes your parts cost. Not to mention all the ones that had the noisy black drum units out of the box. It doesn't make for happy parts time.
