    New Enlarger - Strange ring around image

    Hi,

    I recently acquired a Durst M605 Colour enlarger and when I turned it on I noticed a weird ring shape being shown. I've attached the image. Can someone tell me if there is something wrong with the enlarger?

    Thanks.

    Welcome to APUG!

    When you adjust the focus, does the image improve?

    Is the head turned slightly from the vertical?

    Thanks Matt. When I have a negative in the carrier and I adjust the focus the image seems to focus without any issues. I also check and the head is set to 0 degrees. I noticed the top half of the head moves when I insert the negative carrier and there is significant light leak on one side of the carrier. It doesn't seem to sit flush.

    I've attached another image to show the weird square and ring. Click image for larger version.

    There may be something astray in the light path.

    It has been years since I used a Durst M6xx series enlarger, and even longer since I had one opened up.

    You probably need to attract the attention of one of the Durst users here on APUG. For future reference, it would probably help if you had included Durst M605 in the thread title. No one would mind if you started another thread for that purpose, and linked to it here.

    Have you checked the manual?: http://www.jollinger.com/photo/cam-c...Durst_M605.pdf

    Thanks Matt I'll take a look at the manual and repost with a different title.

    teekoh, if you can twist your body enough to get your eye up to the enlarger lens, you'll be able to look inside and likely see what the problem is.

    It'll be bright, so you might want to use an extra-dense negative, or neutral density filtration, or even sunglasses. If it's too bright for you, don't persist. (If your eye can't focus, rack the enlarger lens in a bit, as though making a very large print.)

    I've never used one of those enlargers, but my guess is that a light baffle or similar is not fully seated. Good luck.

    As it us a Durst, it depends on the light being reflected by a mirror. The mirror itself may be damaged or out of position.

    I took a look inside and noticed the square is in fact created by the light baffle which was confirmed by moving it up and down. The strange circle is actually a silhouette of the piece of metal underneath the negative carrier and above the light baffles. I have no idea what the purpose of that round metal piece is for however. It's held in place by several screws so I'm guessing it serves a purpose somehow. I'm going to see if I can locate the mirror and figure whether it has been dislodged.

    I think we may have a terminology problem.

    I don't know of any light "baffles" that one might find below the negative holder.

    There should be a bellows, a lens stage, a lens panel and a lens below the negative holder. As you adjust the focus, the bellows stretches/compresses and the lens stage, panel and lens move up and down.

    My M605 does the same thing (the circle anyway), I figured that's just the way things are with these pieces. Doesn't bother me since the circle always fall outside the paper when I'm printing, and it doesn't seem to fog the paper either.
