This guide is for scanning based off our experience with a CanoScan 9000F Mark II. This may or may not be able to be applied to other Canon scanners.
You’ll need to install the CanoScan software that came with your scanner. This should include software called “ScanGear” or “Canon IJ Scan Utility”. When opened it will look like this:
Click the ScanGear button on the right side to get started. You’ll be presented with a screen similar to this:
To get a clean untouched RAW scan at the best quality we’re going to need to adjust settings. It’s best to click the Advanced Mode tab along the top to begin with. You’ll want to set your settings to the following:
The result of these settings will be a RAW scanner sensor output. It will result in a “flat” color profile that may not look pretty and fairly dull. However, this preserves the untouched image data for archival purposes and with an IT8 profile we can create and attach later it will look much better.
Now you are ready to scan in your items in high quality with your CanoScan 9000F Mark II!
If you want to enable 48-bit scanning continue below. Again this is NOT required.
See highlighted picture below:
This will allow you to select 48-bit mode from your Canon Scanner if you choose to do so in the main scanner window.
