I have quite a few MP9002's that I support. I am seeing more dusting with these machines than the previous model or even the 6002/7502. Ricoh released a TB to adjust some fan settings and process control and it made things terribly worse. I am having to do developer changes early in order to correct some of the issues. Anyone else dealing with this?

Re: MP 9002 Dusting
You have failed to mention how many copies/prints are on these machine. Toner scattering can result from bad development filters and/or toner separator case that is past its recommended PM count. If I remember correctly, the 6002 and 7502 run the motors at the same speed and achieve different ppm by changing the timing between trail edge of one sheet and lead edge of the next. The 9002 however uses higher motor speeds. This leads to greater developer churning and scattering. If the customer has a booklet finisher and does a lot of 4 and 6 page (2 and 3 sheets) booklets, the copier spends a large amount of time churning motors while it is waiting for the booklet folding to complete. You can also get greater scattering with low pages per job ratios. -
Re: MP 9002 Dusting
I've got 1 9002 in the feild, It's been out there for 11 months. I don't worry about dusting because the customer is running the crap out of it!!! 11 months and 1 million clicks. Yeah it will get dirty but I get life plus out of ALL the PM stuff...............................Mystic Crystal RevelationsComment

Re: MP 9002 Dusting
I have one of these in the field. It's not a high volume machine, but I've been there 3 times since install to vacuum out the ledge on the PCU cradle. I went there today with the intension of doing a PM on it, but it has only done sub 190k. This thing is over toning itself to death. At least it doesn't throw the toner all over the inside of the machine like the older models.
Next job is to find a way of stopping this.Comment

Re: MP 9002 Dusting
Their are 2 versions of this m/c one is designed to do big runs and one isn't
If the pro version is only doing odd and small copy Jobs,it will create issues as it uses more waste toner etc etc.
cheers

Re: MP 9002 Dusting
It's been a few weeks since the last post. I have run into more machines with the dusting issue. I am finding that the seal on the toner supply unit is separating from the "regulator" plate. This is saturating the developer and causing it to dust like crazy. I've been seeing the failure as early as 400K. This seems to be an issue on these "2 series" machines.

Re: MP 9002 Dusting
I am seeing this same issue on all the machines that use B0649645 developer, 6001 thru 9002. I have done 10 to 15 PM'S on this series of machine over the last couple months and have had the majority of them come back up for poor copy quality way short of the projected life. Anywhere between 36k to 90k. Just had a 9002 with only 550k total on it come back up today for the second time. I did the original PM on this machine about 80k ago it ran 44k before it puked out so much developer that it filled up the catch tray or whatever you want to call it right by the drum. At that point I replace the drum and the developer unit along with a new bag of B0649645. It only ran 36k this time before it was full again. This is the same thing that is happening with the rest of em. Talked to a few other techs today that are seeing the same issues. Im thinking the DV that's being supplied is not up to snuff. Im seeing this on machines that have 500k to 3.5M total copies, WTH is the problem. I think the DV is.Comment

Re: MP 9002 Dusting
I also was curious about the developer itself, I have machines like lanier 360s and gestetner 755s that use that same developer and lately even after their PMs i am seeing more and more early failure with developer going light or washed out within 80k to 150k pages, some are not as much volume as they should be but these machines have run years without this much of a problem until these 6002,7502, and 9002s which really aren't lasting very long at all. A recent 6002 in the field has under 120k pages on it and had to be PM'd already due to dusting and washed out pages. I have also noticed on these newer mp301s that are a redisign of the mp171 styles are craping out way early as well, their pcu's are crapping out about half life and get really dirty as though they are leaking all over, and their fusers are getting broke left and right.Comment

Re: MP 9002 Dusting
At this point I think the problem is with the Toner. In the last couple days Every call Ive been to on the 6001 and 2 series has been for copy quality, smudges background and streaks. What leads me to believe the toner is the problem is that it doesn't matter if the machine has recently had a PM DV change or if it was done 5 or 6 months ago. The problem is starting to show up now. I saw a machine today that was PM'd in September but the customer had only put about 180k on it, I also saw a machine today that was PM'd on the 5th of Feb with 73k since the PM yet both machines exhibit the same symptoms, streaks background and smudges. All my fellow techs are seeing the same scenarios and we've come to the conclusion that Ricoh has a problem with the toner that's being produced for these machines. A couple techs said they've noticed that while vacuuming that their seeing toner blow through the filter. I'm going to keep an eye out for this also. If anyone else is seeing more and more of this I sure would like to hear about it.

Re: MP 9002 Dusting
Yep, it's the developer, it's loaded with a black waxy crap that builds up on the mag roll and prevents efficient toner -developer transfer. You get light copies and a filthy machine. Scrub the mag roll with scotchbrite and a little alcohol, (you don't want to get it into the developer assy). Finish cleaning with a damp alcohol rag. Add new developer and go to the next machine which will need a developer change. Apparently in their quest to become environmentally conscious they changed the formulation and now we live with their poor chemistry. It's been happening in every generation since MP6000's. Of course, Mr. Phelps, they disavow any knowledge of this and you are on your own. Needless to say I don't recommend ricoh anymore.Comment

Re: MP 9002 Dusting
Recently bought three of these models, off lease, with 65-150k. All three are dropping toner into the frame of the drum unit, below the mag roller. Just changed dv on one of them. The mag roller was filmed over with toner just like the wonderful MP4000/5000 series. These are machines that sold for upwards of 20k and are suppose to be production machines. What a joke, when you have to go in and vacuum toner out every 30 or 40,000 copies.Comment

Re: MP 9002 Dusting
I have just had the wonderful Friday afternoon pleasure of the 9002 toner "DUMP"..
it just smacks of the Alex toner & dev problems.... have Ricoh learnt nothing..
still nothing is going to spoil my weekend

Re: MP 9002 Dusting
If I have learnt anything, it's that Ricoh does not learn from their mistakes!
Look at the SC-555 codes on MP6000, then on MP6001, then on MP6002, I suspect the MP6003 will have the same problem, why would they not?
They don't learn, they don't fix.Comment
