Printing 6x6 negatives with Omega c760

[brothernature]

I'm trying to print 6x6 negatives with my Omega c760. I've been printing 35mm no problem for a while now but when I go to print 6x6, it seems the light is not dispersed evenly over the negative. I'm using a Nikon 75mm lens and 6x6 negative carrier. Any ideas what would cause this? Photo attached.

Thanks!

Mixing box?

Do you have the extra condensers for 6x6? You can't use the one for 35mm. There's free manuals in pdf form on the web. You might want to take a look at them and see what's up, but it sounds like it's a condenser issue.

For Medium format, you should be generally using a 90mm

You can use a 75 or 80mm lens for printing 6x6 negs. Do you have the condenser or dichroic head? If you have the condender head, check the manual as it used different condensers for 75mm and longer lenses. http://www.jollinger.com/photo/cam-coll/manuals/enlargers/omega/C760 Modular Enlarger System.pdf

That was it! Thanks. I forgot about the other 6x7 mixing box that was included.

There still seems to be a slight vignette at the corners. Anyone have experience with this specific enlarger? If so, how do you find how the carrier sits in the enlarger? It seems if I push it back all the way it locks into place and sits flush, but then the light passing through the negative isn't even. However, if I pull the carrier out slightly, and it doesn't sit flush, the light passes through the carrier evenly, showing a nice square outline on the easel. Just wondering if this is how it should be.
