Sure, you can build a glass tray holder. I've done so, and it works fine. You may get Newton's Rings using smooth glass, but you can always wet-mount if needed.

I have an old tray from a Scitex 340 scanner. It has both ANR glass bottom and top. If I get all the metal parts out, the glass seems a bit larger than the window on the Cezanne. Maybe someone could cut it down.Originally Posted by Peter J. De Smidt
It's been a while. I have been kept very busy at work, but I managed to get a few things done with the Cezanne.
I've updated to 1.0.4 (taking note of the serial number on the splash screen before that is advised).
Checked memory assigment in OS8.6. Disabled VM in OS8.6.
A made a few test scans and then I noticed something interesting (in a bad way).
Here a detail of a 13x18cm negative.
And here is a detail of that detail, see the vertical lines in the back of the chair? They are actually parallel to the CCD and look just like out-of-focus lines, or maybe where the buffered images got joined...
Any ideas?
I have had issues with this or something similar to this before. When I followed the procedure posted earlier in this thread to clean out the inside of the scanner, including the mirror, these lines were largely eliminated. Yet I still get them on occasion.
I read in a thread on this forum that someone was having similar issues with a drum scanner. He suspected that voltage fluctuations were the culprit, and when he added a line stabilizer and surge protector, this issue diappeared. I think if you run a search for line stabilizer you might find the post.

The plot thickens...
Peter Y.,
I re-did the same test using a stabilizer I had here in the studio. It is not the Sola CVS mentioned in the thread you were talking about, but I decided to give it a try.
Results are practically the same:
and the detail:
I believe either it is voltage or dry mechanisms. Have any of you put some grease on those shafts? Or even under the tray?
A tech told me that if the rails needed lubrication to use a very small amount of high quality watch oil.

Peter, how hard would you describe it is to move your tray by hand? Mine feels very heavy, maybe there is something holding it back.
My scanner's carriage requires a lot of force to move by hand, and so that's not unusual. Did you get my private message?

Mine requires quite a bit of force as well, roughly equivalent to that needed to slide a large brick across a table-top.
