I work for a school district that has several Ricoh Aficio CL3500N printers. The printers do good when they work, but they go through PCU's like no other printer I have ever seen. I have talked to Ricoh Tech Support and had help on a couple of different issues, but no help as to why these machines keep going through PCU's... Black and Color PCU's having to be replaced or start showing lines within a month or two of being changed. I have looked around for a reason why these printers just don't hold up. I have cleaned and worked on them repeatedly, but the only thing that seems to work is replacing the PCU. I am looking for any suggestions or help for the Ricoh Aficio CL3500N besides chunking them all out the door.
These machines were actually made by Panasonic and they eat PCU's there is no rhyme or reason, they just do. I would replace all of them as soon as possible. These printers were pretty much interim technology for Ricoh until they developed thier own engine. I highly recommend the new 400 color series, low cost per page, vg color and consumables last a long time!

I had the same issue with my CL3500N. I kept taking out and reinserting the color PCU with the same resulting error. However, I fixed my problem. My color PCU is now reset and printing
Instructions on how I fixed the issue:
1) Turn off the printer and remove the color PCU from the printer
2) Look inside the printer where you removed the color PCU and you will notice three attach points (gears) that each of the three color PCU rollers connect to the printer.
3) Notice that each roller inside the printer has an arrow stamped in metal pointing toward it. On my printer, one at approximately the 2 o'clock position, 9 o'clock position and 3 o'clock position.
4) On the color PCU look at the end of unit that you insert into the printer. Notice the white female connectors on each of three rollers. Look closely and you will see that there are notches inside each connector (gears). One of those notches is longer than the others.
5) For each roller insert your finger into the white connector (gear) to rotate the roller so the long notch aligns with the arrow inside the printer. Be careful not to touch the photo sensitive area of the roller.
6) Insert the color PCU into the printer and turn it on. May need trial and error to align the notch correctly, but it certainly worked for me.
Hi, thin black lines are most likely (but not definitely) caused by something in the black PCU (photoconductor unit), either the drum or the charger. Replacing the black PCU will likely get rid of your lines. The Ricoh code for a black PCU if you don't already have one is 402448.
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.
The voids and blotches can be a bad black pcu, the voids san also be toner on the glass slat obove the pcu,s there are 4 slats one for each color, on the pcu itself on the upper side is a narrow long opening, the glass slat is above this opening when the pcu is in the printer. It will take a flashlight to see any toner on the glass.
sc441 error means one or more of the developer unit(PCU) isnt rotating. you have to take the PCU out to see which color isnt rotating. there maybe one of the doctor blade is flipped, usually caused by lack of toner in the PCU.
One of our Ricoh CL3500N printers- less than a year old- gave us a "color regist error" after changing the transfer belt.
Ran the "adjust color regist" without results. It would just finish and pop back up with the same error.
Color test page printed no color, just BW
I reseated everything, and even replaced the PCU without positive results.
A couple hours later I went back, took everything out (be sure to keep the pcus out of the light!), and vaccuumed the heck outta that printer.
For whatever reason- maybe there was a chunk of toner hanging out, maybe I knocked something loose or back in place, whatever- but when I put all the parts in and turned it on, the error was gone and color printed great!
