I've never had this problem with these models. If they're OEM then you should warranty them. Check with tech support for any calls they've received on this issue, maybe there was a defective run during manufacturing and only affecting certain markets.

I would second teebee1234 never had this problem on these machines from the 1515 right up to 171.

Further to my other post in this thread, I have seen a couple of these PCU's fail to automatically initialize dev when a new unit is set. I think they may have been knocked around in transit and the contacts on the drive gears are already disconnected. Also everyone Ive seen lock up the drive has had toner spilling everywhere.

We have sold loads of these lately, I hope I don't have to become a warranty returns expert.

This problem is vary bad. I live this problem (200 machine).

We sell the Ricoh AF1515MF it's good machine. We install the new machine (1515MF) machine work with new drum 80maybe 85K,
After Ricoh produce the MP161SPF, Some machine work same the airplane. (Polygon mirror motor sound) some machine drum unit fail 45-50K,
After Ricoh procuce the MP171SPF and I think produce the new drum unit. They are change drum unit.(Quality) Some machine has adress book data error. (Upload the new firmware, SP-5-801-014, SP5-846-050-Clear UCS Setting, Int. All Adress book) some machine work is good some machine not work. It's time We replace the controller board. And machine is work. And I installation a new MP171SPF after the only 5k IT's show the SC-500, Yes it's main motor lock code. But Main motor is work. Trouble source is drum unit. We use the our machine non original toner. I think this face drum unit is fail early. We open the drum unit We show the drum unit gears is fail. We replace the gears after drum unit maybe work 5-10k after dıztt gears is fail. We develop a solution for this trouble. I create a pdf document and share with you.

I'm too scared. Because Ricoh produce the MP201SPF Now this model shred the gears maybe after the 2K
I hate the Ricoh, I hate the Ricoh MP161SPF, MP171SPF, MP201SPF,
I love Ricoh AF-1515MF, I have a machine. Machine counter is 640K. I replace the drum unit 60K machine work. I replace the hotroller, pressure roller, machine work. I don't change the main motor or polygon motor. MAchine is work. He is running record(guinness)

I jinxed myself, I had an SC500 yesterday on the mp171. PCU was locked tight and some developer leakage out of it. I'll inquire around the office and see if anyone else is having an issue with these.

Hi,
Remove the all developer and use half of the developer then you try, may be problem will fix.

You don't rebuild these pcu's, the entire assy is replaced. In any case, removing half of the developer from any unit, any manufacturer will make it non functional.
