MP4000 drum in older machines

[rthonpm]

Here's a crazy one:

So I got desperate a few weeks ago and needed to do a drum replacement on a 2035, only to realise I don't have an A230 drum. I did however have the new D009 drum for the MP4000. The only difference between the two drums is a longer 'lip' on the end of the D009. Other than that, they are the same size, and the gear is in the same direction so I figured I'd see if it would fit into the drum casing... What would you know: it fits in the older cases! I've only tried this with one other machine, a 3035 and in both cases, though it's a little tight until you seat it correctly, it works without any issue.
I'm curious as to whether or not anyone else has tried this, and if so, if have any 'long' term issues been seen? I wouldn't think there would be any as this family craps out in terms of copy quality at the drop of a hat anyway so it would be hard to tell if something is truly related to the new drum or if it's just a normal failure for the machine. Also, as the new drum is cheaper, and I'm one of the poor souls who has to deal with BEI, it would help to keep my parts cost lower and also allow me to carry one fewer part.

I am glad to hear it fits. I had wondered if it would work, but hadn't run into the need to try it.

I probably shouldn't ask, but could you make it any worse?

The way I look at it, the new style drum can only make the machine run better. Maybe the larger lip on the end towards the drum shaft will help keep some of the waste toner inside the unit instead of puking its guts out everywhere else.

I had this the other way round.An A2309510 in an MP5000 and it caused nothing but trouble.The machine would last about 5K before doing the usual background thing, so I got pissed of and tried the correct drum and new dev(AGAIN!!!) and havn't heard a thing since.

I was at another machine in the same place and nipped in to check, and it had done about 15K.So here's hopeing it works.

The A230 drum has that shorter lip in it on the side towards the drum shaft. Probably sticking it into the new machine it never made the right contact. I've always stayed away from testing forwards compatibility.
I will keep an eye on my two test cases though. It's been close to two and a half weeks on the first one and nothing has happened.
The 3035 should be a better test though as it gets a better volume.

M5000

Anyone tried putting B0799640 dev instead of the b296 that the TSB asks for? I didn't have the newer style and used the B079 and copies looks great.

The backgrounding the MP5000 starts getting with less than 100k was addressed in a TSB.
The mag roller had to be scrubbed, the toner/dev mix adhered itself to the mag roller, where only a good scrubbing with citrus cleaner could clean it up.

Anyone use the older dev with this? and what do you think the reprocutions will be if any.
I understand the mp5000 toner is the same as the 35/45 series toner, except the bottle is different.

There were a few posts on another thread about using B079 or B003 dev/toner in these machines - had one tech set it up and was testing it. Working great out to about 4k if I remember, but no long term results yet. The toner is different, and is why the mag roller keeps getting trashed. That means a new hopper and possibly drive motor. Also the melting point is higher for the B079 machines, so there were a few adjustments to the fuser SC codes. My concern is a toner inclusive customer getting the "right" toner for the reverse-upgraded machine.

The Ricoh engineers would have a hissie fit if they knew we were talking about this, but then again if they would get over their rectal-cranial impaction and actually fix the problem...
