Bringing a 73KG High End Scanner Back to Life

Sometimes I ask myself, how do I get myself always into these enormous projects. Maybe this is how everything is supposed to be in my life. Or somebody putting these big pieces of work in front of my and tries to find out if I will ever give up. But thats where I a have to disappoint, I hardly give up on something.
I was looking for a bigger Scanner for many years, because I wanted to be able to scan my ultra large format wet plates. In the video bellow you can watch my full story. Underneath the video I will go into some details. Find out at the bottom of that post how you can support me and my work to make this postings/videos possible.

Here are some details about the Screen Cezanne Scanner:

53x34cm (13.4″ x 20.9″) reflective & transparency scan surface
5300dpi
32-bit CMYK, 48-bit RGB, 8-bit grayscale
Interface SCSI II
supported formats TIFF; DPS; DCS; SCITEX CT; JPEG; YCC
73kg heavy
Software: Color Genius 2.1 and 1

Still smiling – didn’t know back than what I got myself into again

Picking it up and bringing it home was a bit of a challenge. But somehow we managed to get it into my studio. Please be sure if you get yourself such a beast, that you put it into lock position before you transport it. Then you can also unmount its wing. Check the Maintenance guide here

Yes, I could have just used the Power Mac (433mhz) that came with the Scanner and it would have been all over. But, then I had to use the use Firewire hdd, or USB 1 connections. Did anybody of you guys ever tried to copy large image files via usb 1.1? So USB 1.1 transfers with about 12 mbit, thats little under one megabyte a second. Believe me, you don’t won’t to copy many gigabytes over that connection. Other than that, the original Mac was pretty slow wit MacOs 9. All tools I describe here are listed here list.mhaustria.com

There cam a working Power Mac with the scanner – but it was pretty slow

Thats the reason I got a used Power Mac G4 Quicksilver with dual 1.2 ghz and 2gig (I said wrongly 4gb in the video) of ram. You can see in the video how cool it is and that it came with an Apple Cinema Display in its original packaging.

While I set everything up, I got a scary surprise over night, luckily nothing was damaged. More about that in the video.

lot of broken things, but nothing really broken

Even it was much faster, I needed to upgrade it with an USB 2 card (be sure to get one with a specific new chipset – (links to it at and everything else here list.mhaustria.com), an ssd, a Power Domain 2930 SCSI card (I got a sealed one, check it out in the video) and an PATA/SATA Adapter. This made the Mac really quick.

felt like a little kid with all this original sealed packaging

Long story short, cloning (with carbon copy cloner) everything on the ssd, did not bring any success. Because the old MacOS 9 would not run on the new Mac and the preinstalled Mac OS X would not support the SCSi controller.
Thats why I installed http://macos9lives.com and MacOS X 10.3.2 Panther from the apple website. MacOS creates easily a multi boot when you install one OS after the previous one. To connect remotely with screen sharing form Mac OS X to Mac OS X you just have to enable the feature. For Mac OS9 install this one: https://www.macintoshrepository.org/155-vine-vnc-server-3-5-for-os9

you can use screen sharing on your Mac, but sometimes I had the feeling vnc is quicker

As you can se ein the video, coping files over 1gb ethernet connection is great. I can get about 60 Megabyte a second out of it. that is more than 60 times faster than usb 1.1

Now everything was setup and ready, I worked on a ultra large format wet plate. That was a great opportunity to see what the scanner can do. This is a 30x40cm collodion wet plate. Shot on an ultra large format camera with a Voigtländer Heliar Universal 360mm F 4.5 Lens

The portrait wet plate portrait session with Roman was great.

Now it is time for the first scans. The results are amazing. Just a little hint for reflective scans. Always try to use a black background, otherwise you get light bleeding into your image. The files this scanner produces are beautiful. There eis not much need of any post processing. That saves so much time. I love it.
