Hello,
scanning has been improved several times since 2022, so please update to the current version of PDF24 Creator first.
When you start the import from a scanner, the window "Select source" lists the scanners in groups (x86, x86 MS, x64). The same scanner can appear in more than one group, because PDF24 can load its driver in different ways. If PDF24 closes when you choose the SCX-4216F in one group, please try its entry in another group.
If PDF24 still closes with every entry, please let us know here which entries you see for the scanner and which one you chose.
