ScanSnap S1500M and Mac OS Monterey 12.6

Good day to you martona22,

We’re going to recommend you follow these steps to set up a scanner with your Mac - Set up a scanner to use with Mac

1. Before setting up your scanner, make sure macOS has the latest scanner software available to it. Check with your scanner’s manufacturer to see if any updates are available for your scanner model.

If you have a multifunction AirPrint printer and scanner, you don’t need to check for software updates.

2. Follow the instructions that came with the scanner to unpack it and connect it to your Mac.

If your Mac has a single USB-C port, and you want to connect a USB scanner, use a multiport adapter. Connect the scanner, then connect a USB-C cable to a power supply to prolong the battery life of your Mac. See Use USB-C cables with your Mac.

Important: Don’t install software that came with the scanner. Your macOS computer downloads the latest scanner software automatically.

3. Choose Apple menu > System Preferences, then click Printers & Scanners.

4. If you don’t see your scanner in the list at the left, click the Add button. If a pop-up menu appears, choose Add Printer or Scanner.

5. Select your scanner, then click Add.

If your scanner isn’t in the list, see the documentation that came with the scanner to find out how to scan with it.

Thanks. 

You need scanner drivers compatible with macOS 12.6. If those are not shown to be compatible per the Fujitsu site, then the optional, paid VueScan Professional application can drive this scanner without any vendor drivers installed. You can try VueScan Professional as a trial to see if it meets your requirements.
