ricoh aficio 650 developer

[Guest]

gud day sir/madamme;

Is there a expiration for a developer used in a ricoh aficio 650? How would I know if this is really expired?

The developer has a 300k life

300K or one year in the machine, whichever comes first.

Though I have seen it go longer than a year in some cases...others after a year and not 300K yet it goes toes up and starts dusting. Never seen any good come from trying to stretch it longer than 300K.

Few things in this world are more finite than Ricoh developer material.

You mean when the developer will come out inside the machine when you start copying? Is that a sign that a developer of the machine is expired already?

That problem can be a multitude of problems...

Developer needs replacing. (Developer 'bearding' on lip of unit)
Developer Bushings worn out. (Developer leaking from the ends of the unit)
Developer Bias problem. (Developer on copies...grainy feel on copies)
Drum Ground bad. (Developer on copies...grainy feel on copies)
Drum worn. (Inspect the drum for wear lines especially at front and rear)
Wrong developer (Make sure you are using OEM A2299640 Type 7)

I'm sure there's more. Can't think of more now.

Whoa, where have you seen or heard about a "one year" life? I've never seen (or noticed) that as a published limit. You've got me thinking I should be looking the age as well as cc as a metric for when I need to PM the developer.

Personally, I've always felt that old rollers may need to be replaced even though they are short of their rated life based on feeds/copies. I get pooh poohed whenever I bring that up at work. Oh well, whatever works.

Drums and developer both have a "use life" regardless of how many copies have been made. 1 year is a ball park in most cases for both drum and developer. You can get more out of them, but if you are having issues, it is something to look at. (Older drums tend not to be as sensitive).

Saying that I've just done a 6-machine install today that replaced Adonis-C2's with Apollon-C2's. One of the Adonis' had only done 29k in it's life and was on it's original drum and developer. Copies were perfect, hot roller was spotless, pressure roller looked as if it had just come out of the box. Needless to say I was bloody amazed!

I'm not questioning the idea that there is a life limit measured in time rather than copies or developments. In fact, I agree with that. I just want to know where you heard about it.

I've been working on Ricoh machines for over 7 years. It was only a couple months ago that I found out how to do a soft reboot of the darn things from the console. This after having been to 4 on-site Ricoh classes and who knows how many e-learning classes. I know I don't know everything there is to know about Ricoh machines. But, these (reboot and PM life) seem to be pretty fundamental to working on them.

I've been working on Ricoh's for 11 years, and I've never seen the 1 year thing either. (stumbled across the soft reboot in a service manual years ago, but AFAIK it's never been taught in any of the classes - pity.)

I can see pressure rollers going bad after a year in service, but I've had drums and developer sitting in my car stock longer than that (oddball machine) and had zero problems with them.

I have had drums get light fatigued in analog machines when the customer leaves the plated open, but that's not gonna happen in a digital. I've also had feed rollers and transfer rollers dry rot, and developer for some of the new machines REALLY doesn't like being left in a car in the Mississippi summer heat. I'm just wondering what could possibly age a drum or developer inside a barely used machine as opposed to in the back of my hot/cold bumpy car.

Cuz most of the instructors hardly ever see the real world. Though I have had some great instructors who have taught little extras like the soft reboot and other goodies...depends on who's teaching and how much you want to learn the little tricks. I've been in classes where there has barey been time to fit in the basics let alone extras. Usually due to that "one tech" in the class that "knows everything" and tells everyone how good he is.

In the color machines...auto color calibration. In the B&W process control running at intervals. Cycles on the units not necessarily pages output.

Process Control certainly eats revolutions off a drum, but only when the machine is actually used - if it's not turned on or sitting idle, no ProCon. I can see that factor cutting a PM in half but I never heard of it in terms of a 3 month or 3000 mile oil change. Maybe because I work mostly print shops and HV machines - sometimes I PM a machine 4 or more times a month...

Most of my HV (60ppm or more) machines run much better when they are 'run hard and put away wet'. I think because they weren't designed to be sitting on the sidelines waiting for a user to walk up an make 3 copies now and then.

I've got a couple 90ppm machines that are barely used at all...1-2K monthly at best...and I see them more often (based on copies between calls) than the 90ppm+ that run 500-700K and up per month.

Hehe----rode hard----


There are still customers that cannot understand when I've talked to them about having an 'appropriate' machine for their environment.

Right, that's why there are little Toyota minitrucks that are pulling a 38' 5th wheel toy-hauler. Oh, I'm sure some have tried!!!

KopyKat, I totally agree with you. At least now I am in control of who gets what, and not a salesman, so the 'appropriate' machines are placed into their respective environments. Damn, what a concept.
