I haven't developed prints in a Jobo drum in a very long time. I'd like to develop some 8x10 Ilford RC paper negatives in a 2830 drum in with a CPP-2 + Lift. I'll just develop one sheet at a time. With film, the reels are loaded with a plastic tube core, and that core fits onto the Jobo top. Does one need to use one of these black cores when developing prints to keep the drum light tight? I can't seem to find the info in any of the manuals.

Jobo made a plug that fits the inside funnel of the lid, if you lack that you can use the tube I believe to keep it light tight.
Also, they made a cup that snaps in the lid for the print drums
Thanks, Erik. I probably have one of those somewhere....

It came with 8 clips to separate the negatives. 4 of these clips have a kind of wing. Does anyone know what these are used for? As separation or as a stop to prevent the negatives from sliding upwards?
I have also attached a document with details of the capacities....

I am unsure if all of your questions can be answered here, but it's a good place to start researching:

We never have time to do it right, but we always seem to have time to do it again...
Thanks, Kino. I did look through those.

Jobo documentation is sometimes hard to find. Seems that they came perilously close to going totally out of business in the late 1990's and a lot of whatever documentation was available online disappeared.
Some has been restored to the Jobo USA site, but I don't think it all survived this dangerous period.
Unfortunately, you'll probably only find answers in online forums from actual/past users.
Good luck!

The clips with wings are intended to stop smaller prints from migrating when you load a lot (say multiple 4x5 in drums that will do it). The simple clips are to help retain the paper in the channel.
