Canascan 9000F distorted output

[Dino]

Hey Forum

I have earlier written concerning a problem I have with Canoscan 9000F and Canoscan 9000F Mark II. I have further information. I will post it all.

I had worked with Canoscan 9000F on both my 32 bit and 64 bit Windows 7 computers. I have never had any problem, I was actually very impressed with the software (Silverfast SE 8.2).
I also have a Plustek Optekfilm 8200i using Silverfast 8 SE Plus.

Then about a month ago I wanted to use the Canoscan 9000F again. I wanted to scan BW negatives

The preview picture was OK, but the scanned final output was very distorted.
I thought the scanner was broken and bought a new scanner Canoscan 9000F Mark II.
That did not solve the problem. I tried both the old and the new scanner on 32 bit Windows 7, 64 bit Windows 7, 64 bit virtual Windows 7, 64 bit Windows 8,1. Same problem.
I then the used the software that came with the Canoscan 9000F Mark II and had no problem with the output. The output was not distorted. I prefer to use Silverfast though.

I then tried to scan photoes and found out that the output was OK with both scanners.

I hope you can help solve this problem. I need to know very soon as I still have some days left to return the scanner I might have bought without actually needing a new scanner as the problem was not the scanner but the software.

Dear customer,

Please check if you maybe have iSRD activated for the scans.

The infrared scratch and dust removal unfortunately can not be used for most B&W emulsions.
The silver halide in the emulsion blocks the infrared beam.
The wrong informations resulting from this can cause distorted images.

Kind regards,
Arne Ketelhohn.
