I wonder if he actually does get a discount or is it like when you go to buy a sofa or bed and they always give you 'an extra 15% discount' on top of the '50% off' they already had advertised... when in reality that sofa was never 2 grand anyway and everyone gets the same discount aka the normal selling price behind all the smoke and mirrors.
It's pretty disgraceful that a part could be so shit for so long and nobody has done anything about it.
What do you think about idea to rise up the Vts voltage? It will reduce the toner amount in the development, giving more space in it.... and allowing the gears in development to work more smoothly and with less load, less force....
OK I read everyone's input and I'm going to give my input. It's a bit different so please don't give me grief about it.
OK so this is what I do,
1) I use a 1515 imaging unit. I've never used brand new in a MP301, always rebuilt. And I change the plastic plate on the front end (closest to the door) this allows the unit to lock into a MP301.
2) When rebuilding I use 165-170 grams of developer type 28. This is less then the normal amount of developer in the unit which I suspect is about 200 grams. This will also help reduce breaking of the developer drive gears and reduce leaking.
3) Always inspect the developer drive gears. They need to be in very good condition otherwise don't use.
4) Before the rebuild take the used unit and hold it above some paper, shake it a little and tap the ends a bit. If you see it dropping developer and toner do not use. (only shake it a little)
5) I do a full rebuild of the important parts in the imaging unit. Drum, developer and cleaning blade. Vacuum the waste out. Clean well. Wipe the charge roller clean.
P. S. My units have lasted over 40k by doing this. Just make sure you use quality parts and change the fuser roller at the same time if possible.
Once the unit is done put it in and initialize. It will produce a good print if done properly.
At this point I put the machine into fixed mode for adding toner. This way there's no background because for some strange reason the machine always seems to add a bit too much toner. Just make sure you know the type of prints your client does. Obviously you don't want your prints coming out too light or dark.
I know it's a strange unorthodox method but it seems to work. Clients don't complain and they do approximately 3000 to 6000 a month.
Hope this helps
I know it's an old thread, but since it's been re-born, I'll go with it!
This is great info! I've about had it with the PCU's - even the type 1515 that I've always used and previously had excellent success with are a disaster now too .
I was so fed up, that I've actually gone down the road of installing a Generic version of the PCU, and so far I've had better luck than with the Oem's. While I've installed over a dozen in the last few months, I've not had to replace any as yet, so I can't say how long they last exactly, but I've not had any call backs.
As for rebuilding...I appreciate the tips, and I might give that a try too.
It's interesting that you say you're using only 165-170g of toner and have had good success, because according to the label on the bag that my supplier sells for the machine, it's 275g. That's quite a difference, but if it's working well for you, then it only makes sense that it would be much easier on the gears with so much less Dev in the unit.

Ricoh came out with a modified MP301 drum unit a while back, D1272212. Haven't had any fail yet, we'll see.
Sure, it's a Genuine Supply Source (GSS) product
Genuine Supply Source Inc. :: Home
But, unfortunately they only distribute across Canada
I did hear about that, but unfortunately, in my case they cost about 50% more than the type 1515 units, and 2.5 times the cost of the generic
