Re: The Much Maligned MP4000/5000

AE040051 unavailable in Canada.
Has anyone found a different roller that may fit?

Re: The Much Maligned MP4000/5000

I brought the subject up with our rep from NA Trading who said he would pass on the request. We have several hundred copiers using this roller and have about 5 rollers left! I think our immediate plan when we run out of stock is going to be to just remove the roller completely. Some posters early in the tread stated success without using any cleaning mechanism. Any current experiences to report?

Re: The Much Maligned MP4000/5000

I have NOT tested these, but was looking at them some time ago as possible alternatives - Mostly trying to get that one-way bearing that kinks up the works out of the system and just go with 2 bushings. Neither of these gave me the necessary extra length, but IIRC they were usable.

AE040042 - this is a slightly smaller diameter than the 0051 roller, but should work.
AE040068 - don't remember why I rejected this in favor of the 0051, but I believe it did fit.

PLEASE test these, and report back! No promises, but one of them should do the job.

Re: The Much Maligned MP4000/5000

Great news. The AE040068 is an exact match to the AE040051 as far as we can see. It cost about $1.50 more but is a "B" level part in the US and is used in the 3260C/5560 so it should be available for some time. The AE040042 is too small of a diameter to work.

I didn't have AE040051 in stock but I had 3 of AE040016. It is a bit shorter and a bit larger of the original AE040099 Holder Roller but it does fit OK. I'm tryin it with a MP5000 but till now (installed 10K copies ago) no problem at all.

Did you actually try the 0042? 0051 rollers are actually slightly larger than the web sponge roller it replaces which puts extra tension on everything - I was thinking the 0042 might be a better fit, and maybe not require cut or weaker springs.

I haven't had occasion to change any in about 2 weeks (minor miracle) but I know they'll all roll in at once. I haven't had any 0051's in almost 2 weeks and they show backordered here in The States for at least another week.

Re: The Much Maligned MP4000/5000

The 0042's diameter was too small. The frame was bottoming out before the oil roller contacted the HR. I had received an email from Ricoh saying that the 0051 was no longer available. The 0068 is available in both the East and West warehouses and is a B level part (the 0051 is a Z ranked part) and appears to be an exact duplicate of the 0051. The "assured availability" for the 0068 is over two years away.

I was wondering if there was a reason for retaining the roller clutch instead of using another of the bushing (AA080353). The only issue we've had with this modification at all has been with the roller clutch locking up (not that it happens a lot). Also, we've found that putting the end of the roller with the lot number on it to the non-op end of the fuser prevents the occasional unwrapping of the "skin" of the 0051 roller.

We have been very please with this mod and have over 200 copiers using it with no real problems. Thanks!

Re: The Much Maligned MP4000/5000

The oil roller isn't quite long enough if you remove the one-way bearing. Was hoping to fine a roller about 1/4 inch longer so we could, but haven't seen anything yet. Packing that end with a little hi temp grease helps a lot - clean and repack each roller change and haven't had a problem with them locking up since.

We played around and found that if you use (2) of D0624192 (Old # B1404192) bushings and (2) of 080733103 washer (bag of 100) you can remove the one-way bearing. We think you could get away without the washers but they keep the roller centered in the bushings. The washer (08073103) show as being out of stock but are a "F" ranked part so they should be available.

I've attached pictures of both ends of this setup (this is a new fuser that hasn't had the web parts removed yet).

Could you PM me the original pictures - I want to update my Tech bulletin with the new part numbers, and would like to include the spacers as an alternative mod to keeping the 1way bushing.

Re: The Much Maligned MP4000/5000

Just a small update on this oil roller instead of web idea,meybe it was mentioned on thread but I don't have time to read it all.
I did similar thing on MP5500,web motor isn't working so I fit in oil roller,now it's ok for a while but after about 15k papers oil roller takes too much toner and starts transfering piled up toner back on hot roller.
Now on 551 machines there is allu cooling/cleaning roller behind the oil rollers that takes on toner and gives oil roller more life.
Problem is that 551 model bushings don't fit in MP web assembly unless I can modify web assembly somehow (electric orbital cutter crossed my mind...) or that I actualy fix the dead motor problem...probably faulty BCU board.
My guess is that oil roller on MP5000/4000 culd allso make similar problems,toner is allso crucial in this case,cause on machine I'm working client use integral toner (the one I hate so wery wery...weeeeeeeeeery much)
So that being said I'm against the oil roller solution,especialy on overtoning pigglets...that's what MP5000 is in my opinion...fancy looking owertoning pigglet with more complicated fusing assembly.

Myself and 3 other technicians at our dealership are using them with no such problems.

Re: The Much Maligned MP4000/5000

The AE040051 oil supply roller mod works like a champ. Cut the springs in half for the correct tension and off you go. I have also just been tossing the entire oil roller assembly (when caught without the ioil roller) and have had ZERO problems with it. For the most part I do the oil roller mod and have been for years with no problems. As for the toner dusting.mag roller coating, over toning issue, I reccomend N/A Tradings' type 4500A toner. We use it exclusivley in the MP35/4500, MP4/5000, MP4011/5001. Works better than OEM.

Re: The Much Maligned MP4000/5000

Ok guys after a weeks training on utax i after to say they are fucking shite compared to the old ricoh kit
but back to the subject been out to a MP4000 call out on me way back from the training again poor copy quality
(latest dev unit,toner,drum unit,etc fitted) but copy quality crap is it me or is it these machines are a fucking hopless
case !!!!!!!!!!!!

Re: The Much Maligned MP4000/5000

Well and truly. PCU, web unit and toner hopper are awful. You would have thought the lesson would have been learned from the B296 developer from the MP3500/4500, but no - it's still being used on the latest model. Shockingly shit machine. I'm also starting to develop a severe dislike of the Metis.
