MP 301SPF Toner Density/High Background

[mikadonovan]

do you mean that the MP301 toner (and developer) is different for Russia and Europe?

Here's an old list.

No I said type 28 developer is for the Russian series that is the product name for that Ricoh photocopier series

Heh) I forgot about this model and didn't understand you, because I am Russian.))
But this developer can be used in MP301, if original developer had been dead after 10k pages, it's cheaper than buying a new PCDU

Well, i think my post took a wrong path...who wants to change
developer and...what type it is!
If normal settings are correct, why PCU'S last only 10K. prints?
I don't care about worn gears...it's another story...

This PCDU really has a resource issue in last time. 10-20k print before the developer dies or gears...((
I often meet similar defects and solve them, as I wrote earlier. After repair they work more 45k pages


Type 28 - B1219640

They only last 10k because they are junk!
When we first started selling this series, it only took about a month before we had a rash of failures at about 10 - 15k with the PCDU's. No matter what you do, you can't "bring it back" to normal, except for replacing the unit. Replacing just the developer might work for a short while, but not a sure-fire solution. Shortly after realizing the units suck, we found out that you can put the 411844 (Type 1515) PCU's in the MP 301 machines (break off a pin on the frame of the machine that meshes with the face-plate of the PCDU). Ever since then, we've had them go to the actual 45k yield they are rated for. Not sure what they did to the D127xxxx units, but as I said, they are JUNK, and we refuse to use them!! Have lodged MANY complaints with RICOH about them, but nothing has ever been done.

Sounds to me like t might be similar to the development roller filming issue Ricoh had with the 35/45 and 40/50 ppm models.

Are you running sp2801 after pcu replacement?

[Keegan Chetty]

We've had every unit (atleast 100) fail within 15k copies, started using rebuild kits which are way cheaper and comes with gears and so far it has been working *fingers crossed*

Yes i do.

Could it be the TD sensor, calibrated to a "higher density" level related to the MP201sp TD sensor??
