Would you believe it's a 1.5mm imperial allen key that fits these perfectly? Talk about 1 step forward and 1,500,000 backwards!

And what's wrong with feet and inches? 'Bout as confusing as pounds and shillings and pence.

It is a bit bizarre, isn't it. I did buy a set of imperial allen keys from B&Q and I've not rounded one of the screws off yet.

I only need to get it out once, and the whole crap Rube Goldberg contraption goes in the garbage, an AE040051 roller goes in there, and it takes >5minutes to change it next time.

How long are the fuser rollers lasting without the web system in there. I haven't had to replace a heat roller yet.

I notice slightly more wear depending on what is being printed, but they still seem to go 2.5xPM VS 3xPM. Honestly, that may be a fluke as I've only had to change maybe 3 heat rollers total on these beasts - the process doesn't hold up well enough to stress the fuser. Its so much easier to change the 0051 roller than it is the web, so as long as the heat roller lasts longer than the developer its a good mod.

Using AE040051 oil roller from Aficio 1055/ FT7900 series.
Have to end for end the one way bearing on the oil roller. Even if it does not last as long, it is way easier to change.

isnt there a flag sensor in the web unit? ( cant remember off hand) if so how does this mod affect that

[Shadow1]

The sensor is up in the unit, but the actuator is attached to the web assembly. The flag drops into the sensor when the web ends, so remove the actuator along with all the other extra pieces and it can't trip the web end.

If you really want, it may cause issues in the future, our team removes the web unit from the fuser and puts the fuser back in the machine. We figure the copier has problems as it is and the previous generations did not need a web, so why now. Haven't had any issues with fuser and I have had this done on two of mine for a year now. The only thing you have to do on every call is reset the pm counter for web consumption because they use a counter method instead of an actual sensor method. Just a thought.

Cool to be Quoted

We have been putting the oil rollers in the MP4000 series and the SP8200's. Have yet to change a hot roller. 400k+ on one. We still leave the PM counter on and change the oil roller at that time. Would still like to find a bushing that fits instead of using the one way bearing, they seem to cease every now and then. Been filling them with heat grease and that helps.

Yeah its cool to be quoted - there's no telling how much hassle you've saved us with that.
If you can find some weaker springs it helps big time - I had been clipping the stock springs short which sort of worked, but the oiler tended to fall out before you snapped it back together if you didn't get it just right. I found 6 or 7 sets in my spare parts box that were perfect, but I have no idea where they came from. Post the part number if you find a good set before I do.

BTW, Ricoh just launched an internal forum -*EXTREMELY*- similar to CopyTechNet... With your permission I'd like to repost this there. I don't know if I'd take any heat for defying the engineers and posting a "Field Tech" bulletin that corrects an obvious design flaw, but it won't be the first time I bucked the system and put my foot in my mouth. I'll make sure to wear clean socks.

Let me know.

I have been afraid to touch anything on the fuser because the web is a pain but the fuser is an ever bigger one and the seem to last forever and I was attributing that to them having a web. If they still go as long I may have to try this.

There are no problems with not having a cleaning roller ?

I don't see a problem with that. I tend to buck the system a little too much too. Have an address for that forum?

If you go to the TSC site there is a link to it at the top of the MP4000 page.

As I suspected, I posted this mod to the Ricoh forum, and it survived about a day before...

I know Ricoh can't post unofficial modifications, but I was hoping the forum would allow techs to get away with it. You know... helping to keep the customers happier.

It took 2 years for Ricoh to release an "improved" toner for the MP3500...MP5000 that didn't come close to completely fixing the problem - there isn't a snowball's chance in hell of something actually useful making it past the corporate censors... um - engineers.

[msaeger]

Yeah they don't seem to bother fixing issues on current models any more you have to wait for the new model and they ones that are out there with issues never get fixed.
