ricoh aficio 650 developer

Absolutely Correct - I see a Pro1356 machine once a month to PM it when it's running 500-700k in that month, but when they don't have any jobs for it and they only run 10k I'll see 3 or 4 times for oddball stuff.

It's actually better to push a smaller machine than to underabuse a big one.

It really can depend on the machine model and environment as far as how long it will run. I used to work on a pile of 6750's back in the day and you were going to visit that machine around once a month and it didn't matter if it was running 2500 a month or 50k+ a month. For 4418's, it was not uncommon to have those go 1 year plus and be working perfectly fine and they would also hold up under a heavy workload as well.

5733 with less than 20k a month was a fairly good machine. More than that and you started taking a chance on it becoming the biggest piece of crap going. (350/450 family is much the same way really).

It really does come down to using the right tool for the job.

For developer life, I don't know that it there is official info on it, but I have talked to a lot of Ricoh people over the years, be it the hot line, instructors, or RTMs and that is pretty much their take. Drums do have a finite age and what changes with them is their sensitivity to charges. Having process control helps, but it doesn't fix the drums overall sensitivity and the result is CQ is just not as sharp as it would be with a new drum. There might be a quick blurb on it in the service manuals from back in the day dealing with organic based drums, but I don't recall any recent schools talking about it either. Bottom line is for normal use, it "should" not come into play and normal use is what most Ricoh schools are based around. Anything outside of that is of course outside recommended manufacturers guildelines and should not apply, so they won't necessarily talk about it these days.

I should add this is not something (drum sensitivity) that is unique to Ricoh, but it is something any organic drum based system has to deal with.

One final note on the developer. While in a car (or elsewhere) it is sealed. Once open is usually when your 1 year guildeline starts. I am guessing it has to do with what the developer is made out of that when exposed to the elements, it eventually will get to the point it will not perform like it should.
