    Ian, the head is not creeping, the problem I have is different: it is very difficult to insert the negative carrier, I have to lift the front part of the head to get enough space for the carrier. Forgive my rusty english...

    There's two adjuster nuts/bolts on the back, on the bit the head slots onto, I guess these can be moved back a bit to help and would pull the rear of the head closer lifting the front where you slot in the negative carriers. I just checked mine and the spring does little except hold the head in place, mine needs a slight adjustment as well.. (Your English is excellent BTW ).

    If you want I can take some photos tomorrow.

    They lift the back of the head, but not the front (the side towards me), that's why I suspected the spring not to do its job properly!

    It's the bottom set that push the head out and seem to be adjustable.

    Does the service manual explain how to do this?

    Not sure - I'll see if I can find it later tonight, it's in storage somewhere at my Mother's house.

    Phiippe, I had this problem too on my 504 Mk4 - but moved the spring on the Head to the lower hub (to put more tension in the spring)

    Now, when I move the lever to release the Neg Carrier, the head lifts enough to slide the Carrier out without difficulty.

    BTW, I never found any reference to this in the User Manual

    Hope this helps

    Thanks, Martin, but my spring is already at the lower hub!
    I also have a 504: maybe I should try to exchange the springs, assuming the one on the 504 is in better shape???

    I just aligned and leveled my 504 tonight and did post-verification with the Versalab laser tool. I shit you not, dot center from top of column all the way down. Amazing enlargers - machines actually. This is how professional tools used to be built. Definitely the best I've ever used.

    Anyone have suggestion for notchy column feel though? I figure it might need some grease on the column guides. When I say notchy I mean one can feel the rollers/surface interaction when adjusting height/focus. It's not the end of the world but it makes grain focusing a bit easier if the feel isn't gritty.
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
