I just purchase a Jobo 3010 and was wondering how much developer should I use in the drum. I'm using D-76 with Tmax 100. Jobo says the min. for 10 sheets would be 500mm. What does must people use with good results?

Nothing beats a great piece of glass!
I leave the digital work for the urologists and proctologists.
I have the same question. Learned a lot from the thread, but for T-Max 100 developing with D-76, do I used it straight, or 1:1 and how much solution for 10 sheets in a JOBO 3010?
I like to use D-76 at 1:1.
I don't have a lot of experience with the 3010 but, I can tell you that 500ml at 1:1 is not enough. I could see the difference between film processed in my 3006 and the 3010. I sold my 3010 and replaced it with another 3006, I shoot more 5x7 than 4x5, so I don't have a complete answer for you, but I would bet on 750ml.
Thanks Allen,
I figured maybe it's around that but was not sure, I would say that would be the average since the min. amount for 10 sheets would be 500 and the max is 1000, so I guess 750 would be a good place to start. On another note, with D-76 @68 how long do you keep your film in the developer with the JOBO?
Thanks

If you are using a CPP2 or CPA processor and you want your motor to live a long happy life I would seriously consider developing 5 sheets instead of 10 and cutting your volume in half. If you are using a Beseler motor to rotate then go for 10.

He was proposing 750 and sounding like he might go higher which I find sounds like it strains my CPP2 motor so I don't use over 500, cutting back on the number of sheets to make sure it's enough developer. I have done the half time split before and it works fine too.
Why not process the 10 sheets and use 500ml for each half of the total amount of time?
500ml does in fact cover ten sheets well. The second increment just makes sure the film has fresh developer.

I've used all 10 slots and didn't see any signs of decrease in my CPP's rotating speed. However to account for some rock and roll in the trough, I've always added 20% more chemistry to make sure it all gets covered. Developer is cheap, but time spent on the Jobo isn't.
