Question about Canon CanoScan 8400F Film Scanner

1 Answer

Unwanted cropping of some 35mm slides using CanoScan 8400F

Using the 'Canoscan 8400F', when scanning slides, whether the older square ones, or the more common rectangular ones, the scanner is often not coming up with the correct 'Film Size' in 'Input Settings', and unacceptable cropping of the image occurs in both 'Simple Mode' and 'Advanced Mode'.

The width (approx 3.49cm) is correctly detected, but the height is often wrong, and if I attempt to make it larger, e.g. approx 2.3 cm (instead of the around 1.9cm or 2.0cm detected), I get the message: "An invalid number was specified".

For me, a fix for this is required URGENTLY! Please help!

I have a Canon 8400F film printer/scanner

'Tain't necessary. And not getting the part can be an improvement.
I cut out a cardboard template that allows me to scan 10 slides rather than the 4 of Canon's official slide adapter.

All the Canon part does is position them precisely so cropping and rotation are automatic. With Photoshop skills (File ' Automate), you can do the same yourself for whatever size. I ended up doing Brownie, 35, and 126 (gasp!) also.

For extra credit, make your adapter(s) out of genuine plastic rather than whatever cereal box you have lying around.

Please see my other postings (wireguy) regarding this same problem. It's caused by a faulty FAU cable.

CanoScan 8400F

Try this:

Open the CanoScan Toolbox.
Click the Save option.
Put a check in the box that states "Display the Scanner Driver".
Click Scan.
Click the Advanced Mode tab.
Make sure Select Source is set to "Platen".
Click the Preview button at the top left.
If the error still occurs, then most likely it will be a service issue.

One thing to check...see if the inside lamp illuminates when you turn the scanner on using the power button at the back left side of the scanner.

Scanning B+W shows dots

Don't use Descreen. That is for scanning things such as Magazines that, when looked at very close, appears to have a lot of little dots that can cause a moire pattern when scanned.

Not scanning

You have tried everything possible!. Try and reinstall the OS. If some dll files are corrupted, this will resolve it. You may have to reinstall all other software!
