Default Durst M601 exposure time problems

I have relatively recently started printing b&w in medium format and am having to use stupidly short exposure times of 2 -5 secs with the lens stopped down to f16.

My negatives do tend to be on the thin side and but the last roll appeared to be reasonably dense and I'm still having the same problems.

I'm printing on 5x5 paper, from square format negs and the lens is a schneider componar 75mm.

What little 35mm I have printed on the same enlarger with a 50mm lens has turned out fine with exposures times of 10 - 20 secs.

Can anyone give me some pointers on what might be going wrong?
