Screen Cezanne Users Unite

[Vord]

Well unless I'm even stupider than I think apparently the CD/DVD drive on this computer is toast.
I can't get it to eject. Of course the "elegant Mac design" team put no eject button on the drive itself and no combination of Command-E or any other xxx-E keyboard shortcut will do it. I'm using a standard Windows keyboard though, maybe that's the problem...?

Hi,

joining the crew! :-)

drove a total of 16 hours in the last 2 days to pick up my Screen Cézanne Elite FT-S5500 from Germany ...
Cleaned up and reassembled the scanner today.

No software or accessories were delivered with this one.
I just have the standard tray ... below there is a diffuse kind of light table.

As I understand I would place the film on the standard tray?
If so, how can it be flattened if curly?

Should I buy some kind of optical glass and place it onto the standard tray (over the film)?

Best regards,
Martin

Hi,

I found the Anti Newton Ring Glasses at http://www.fpointinc.com/,
( searching for "screen" at https://secure31.webhostinghub.com/~...tore/agora.cgi ),
they offer two products:
1) Replacement platen glass for Screen Cezanne FT-S5000 (AN GLASS) 57,3 cm x 36,9 cm
2) Replacement platen glass for Screen Cezanne FT-S5000 (CLEAR GLASS) 57,3 cm x 36,9 cm
Have to measure, but perhaps they are compatible with my 5500 scanner,
which perhaps would also work as a replacement as the standard tray has some scratches ...

Has anyone made good or bad experiences with those or knows about their quality in comparison with the original screen glasses?

Best regards and thanks,
Martin

I'm waiting at an airport. My phone typing sucks...

The screen main tray is 6mm acrylic with a very fine texture. Screen had hold down sheets of thinner AN plastic to hold the negs down. Ime, the textures limit max resolution. I built an mdf frame with an optical glass insert, which I wet-mount the film to.

FP is A reliable source.

I replaced my entire tray for one single piece of 6mm extra clear glass (maybe one step bellow optical).
It works only with wet mount. I had it cut at a local place to the size of the tray minus a few mm to account for the tray's round corners.

Peter and Gui, thanks for the tips about the tray!
Think I'll order some glass from F-Point.

OK, for now I've made experiments with the standard ANR tray.

Overview over the Test Target.
( http://www.silverfast.com/PDF/resolu...t_short_en.pdf )



Detail Crop, scanned at 9000dpi, in-scanner sharpening and adjustments turned off.



Here with USM 500% 0,3px Radius applied in postprocessing.



Resolution is I guess between Group 6 / Element 2 or 3, which corresponds to 3649 and 4096 dpi.
Seems a bit suboptimal, don't you think?
Also a lot of chromatic abberations seem to be going on.

Any ideas how I could improve that?
Could dirty/dusty optics cause that?
Is there some kind of alignment tool/technique to improve things?

Best regards,
Martin

Hmmm, a colleage got this, which seems to be superior in every way:


Here's a crop of the interesting part:


The Calibration section within the "FT-S5500 Maintainer" tool wants some kind of LAB-file.
Does this refer to color-related-settings, or would autofocus also be adjustable?
(Sorry for the German Screenshot, I only have this language version):
1) In the first window, I clicked on "Calibration" (= "Kalibrierung")
2a) In the second window I chose "transprency on the standard tray" (= "Transparenz in der Standardauflage")
2b) Then I clicked on "scan" (= "Scannen") in the second window
3) The third window then says "Open LAB Calibration File"


Has anyone gained access to the mysterious "FT-S5500 SuperMaintainer" tool?
This asks for a password which does not seem to refer to the normal admin password,
more like a service guy password.

BTW, does anyone have a service manual for either Cézanne versions?

Best regards and thanks,
Martin

You should be able to get about 6000 spi. The sensor has 8000 elements. Using anything more than that guarantees interpolation, at least it does in the direction of the sensor, which is front to back.

Resolution test slides are a worst case scenario for chromatic aberration.

Hi Peter,

OK, that's what I expected to be possible when I decided to buy the scanner, and different users seem to report at least 5300dpi - 6000dpi.
I only used the 9000dpi setting to get some interpolation so that the target lines can be better interpreted.

Today I cleaned up the mirror, which was quite dusty, also the lens, which was quite clean.
While this did improve the contrast of the target scan, sadly it did not the solve focus problem and CAs.

As the previous owner did not install the transport locks when moving it into storage, that might have screwed something up ...
When I picked up the scanner, I locked everything down, but I don't really know what had happened before.

Is there any way to tune the autofocus system? Guess only for Screen service men.

Best regards,
Martin

Before considering an autofocus problem, I'd check for the following:
Take the tray out and place it on a flat table, check if it is not bent in any way, or sagging in the middle, for example (tray out of place or not flat enough could throw your original outside the focus range).
Check if the tray fits nicely into its slot and if the height sticking out is the same all around.
If the mirror was dusty I assume the bars on which lens and sensor ride are probably dusty too. I'd use a lens microfibre cleaning cloth for this, maybe even apply a couple drops of oil on it before.

Then:
How did you mount the target to the tray? Center? Edge?
