Re: MP 301SPF Toner Density/High Background
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*Comment

Re: MP 301SPF Toner Density/High Background
The toner formulation is different between the 2 series so its a possibility, I do not miss working on these though I went through so many PCDU units such a environmental waste.Comment

Re: MP 301SPF Toner Density/High Background
The toner hopper is a major point of failure with these machines. If the toner hopper is defective you will see toner all the way down the bottle when you remove the bottle and the discharge lamps above the PCU will be coated with toner. When the hoppers are working as they should the machine will run clean and you will get a better yield from the PCU.Comment

Re: MP 301SPF Toner Density/High Background
The problem with these PCDU's are due to the fact they are meant to run at 16 pages per minute not 31 pages per minute. That being said we have customers that run low volume and have little issues with these 301 machines. We have customers that run average to high monthly volumes and the PCDU's just cant handle the speed,, Hence forth the reason the mp305 got a completely redesigned PCDU for the speed. This MP301 series has been a joke, that was improperly engineered. We never had these issues on MP161's and they are the same PCDU's structure minus the different mix for the toner and dv. I cant wait till we have no more in the field, due to the amounts of PCDU's we go through.Live for something or die for nothing.Comment

This question has been answered.
I would like to have a good print quality for 30K. prints at least, with one PCDU type or another and i know that 411844 Type
runs very good.
So, is it the D127-XXXX itself the early failure with toner density/heavy backgroung, or the toner Type 301, maybe the SP adjustments?
What if i use toner type 201 on MP 301???
Many thanks to all colleagues for your posts...Comment

I have about 50 of these in a school all low use & I never have any major issues with them, or the PCDU failing too early however they rarely hit the PM life.
The first signs they need replacing is overtoning. I guess this model was built with budget in mind as this PCDU design has been around for nearly 20 years!
Let us eat, drink, and be merry, because tomorrow we may die!

Re: MP 301SPF Toner Density/High Background
Just to echo the experience of others here along with my own.
In most cases, it simply doesn't matter which PCU you use (411844 or D1272110). The performance of the machine revolves around what the volume is. IF the machine is run at low volume or even close to suggested volume, you hardly ever hear from them and they generally run fairly well. If it gets pushed hard on volume, the PCUs are junk and won't hold up. In addition, the hot roller won't go 90K either like it is supposed to. The running joke here is a 301 PM is a hot roller and PCU.
These machines are so bad, I generally take a PCU and hot roller in on every call on one unless I was just at it. Like many, I can't wait for these suckers to just go away.Comment
