MP 301SPF Toner Density/High Background

[Polo-022]

I am trying to find a solution to keep this model running like it's
predecessor MP 201SPF. After 10K. prints from PCU replacement
a heavy background appears in front and rear page.

I change some settings :
SP 2932 Toner Density Control from 0 (normal) to 4 (lighter)
SP 2921 Toner Supply Mode from 0 (normal) to 2 (fixed)
SP 2922 Toner Supply Time from 0.5sec (normal) to 0.3sec (less time "on")
SP 2927 ID Sensor control from 1 (yes) to 0 (no)
I have no results till today
Does anyone works on or have a solution to this problem?
Thanks a lot for any input.

Re: MP 301SPF Toner Density/High Background

If you're using the D127xxxx PCDU.....you will generally only get 10 - 15k from those units.
Use the 411844 PCDU's. RICOH doesn't make these anymore, so we get them from an aftermarket supplier.
Nothing you can do except replace that PCDU unit.

What to you think make's the difference between 411844 and D127-xxxx?
The only thing i would suspect is the TD Sensor, or not?

I'll write everything at once.

Check the Vt value.
If Vt is normal (about 2,5v) - developer is dead.
You can replace PCDU or replace the developer to type 28, but only 270g from package.
Also inspect and clean gears and bearings of augers into the developer unit.
If gears are broken, replace them whit a compatible one.
Gears and bearings must be lubricated.
After replacement initialize the developer.

if Vt is less than 1, you have overtone.

Do not use PCDU from 1515 in MP301 because the developer is different

P.S. sorry for my english, this is not my native language.

The developer is the same. Type 28 developer is for the Russian series

I Look after loads of these machines very reliable just put all setting back to default then fit oem d127 pcdu should automatically run setup if unsure just run dev setup

Re: MP 301SPF Toner Density/High Background

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

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

Here's an old list.

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

Re: MP 301SPF Toner Density/High Background

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.
