Flextight Precision II on Windows 7/8/10

My father was a photographer for around 35 years and towards the end of the 20th century he purchased a Imacon (now Hasselblad) Flextight Precision II hybrid film scanner. This was back in the days where digital photography wasn’t feasible for quality and film was king. The Flextight allowed him to scan negatives into a digital format at an insane quality (even by most of today’s standards) and then do things like color correction via software, something we take for granted these days.

The problem with this particular film scanner is that it only has a SCSI interface. Remember these were the days before USB became real popular. Additionally, Imacon’s scanning software, FlexColor, was really only supported until Windows XP SP1 came out. Luckily we had a PCI SCSI card laying around so I could free this scanner from the clutches of the dedicated machine he had built for it that has an impressive slot-based 450MHz Intel Pentium II with 384MB of RAM that uses an ISA, yes ISA… that big old brown slot, SCSI interface card.

For this guide I’m using a Adaptec 2906 SCSI PCI card and Windows 7 32bit. Note that any 64 bit Windows will most likely not work. This is a limitation of the scanner’s drivers, not Windows or the FlexColor application itself.

First make sure your SCSI card is installed and the drivers are updated. Make sure you can see it in Device Manager:

Next install the FlexColor software. The last version made for the Precision I/II was 4.0.3. You can currently get this file directly from Hasselblad’s site. How convenient, because honestly who has a CD drive anymore? After the software is installed if you go up to File -> Devices you’ll notice that your scanner is not there and it is also not detected in Device Manager. Turn on your scanner and reboot your computer.

That last part is important. Due to the limits of SCSI and the Precision II being made in an era where plug and play hadn’t really been achievable yet, the scanner will only work if it’s turned on before your computer. In Device Manager now you should see 8 devices named Imacon P2/DTP Scanner SCSI Loader for SCSI. There are 8 of them because there are 8 possible SCSI channels that the scanner can reside on. We have to install the driver for each of these in order for the scanner to function properly. Right click on the first one and click Update Driver Software.

From the two options presented, choose “Browse my computer for driver software”. In the FlexColor applications directory there is a folder called INF that contains our driver. Browse to that folder and hit next.

It will ask you if you want to install an unverified driver. That’s okay. This thing was made before driver signing was actually considered! For the next 7 in the list go through and do Update Driver Software again. This time, use the automatic search option. Reboot your computer, start FlexColor, and you should see your scanner in File -> Devices now! You should now be able to scan your negatives.

  1. SCSI is not a disadvantage. SCSI has greater bandwidth (data handling capacity) than either USB or FireWire. It’s less popular with manufacturers now because it’s more expensive to produce than USB or FireWire.

  2. FlexColor 4.0.3 and the Imacon Flextight PHOTO and Precision II scanners work flawlessly under Win10 x64 using an Adaptec ASC-29160n (PCI) or ASC-29320 (PCIe x1) SCSI interface card.

    1. Hi,
      I confirm you, I’ve just installed an ASC-29160 on Ebay.
      I read many tread and I found many people who mount many different Adaptec Model. I think for a better compatibility with x64 bit Windows:
      – ASC-19160 (PCI 32 bit) – external 50 pin connector*
      – ASC-29160n (PCIx-64 and 32bit) – external 68 pin connector*
      – ASC-29320 (PCIe x1) external … I don’t know*
      *Take care to the version of external pin connector, there is an high risk to buy the right Adaptec board but a wrong cable.
      Thank a lot!

  3. Hi you all,
    Thank a lot for this post, you save my IMACON Scanner and me!
    I would like to leave my experience now ’cause I’ve just finished a fresh, fully function, installation on Windows 10 64 bit.
    I followed all your steps until the driver installation where I stop because not x64 compatible.
    You need to modify 3 strings inside the IMACON driver placed in ColorFlex installation folder:
    C:\Program Files (x86)\Hasselblad\FlexColor English v4.0.3\INF\WinXP
    Create a copy in the same folder of IMACON.INF, open with NOTEPAD the copied file and change this 3 lines:



    SAVE (not SAVE AS…) and chenge the name in IMACONx64.INF”
    2) the driver is ready but it have not the WINDOWS SIGNATURE… it means you can’t install… so you have to disable DRIVER WINDOWS SIGNATURE
    Go un YouTube and search “Disable Driver Signature”.
    It’s so simple to do, but too long for writing, you can solve in 5 minutes and need to restart.
    3) After to succeffully the Disable Driver Signature procedure, you can follow the istructions write in the main article. You will receive a RED ALLERT from Windows which advise you are installing an uncertificated driver! … If you are so brave you’ll confim and begin to scan wit your IMACON scanner… 🙂

    Thanks a lot again
