Why does ScanSnap Home keep resetting my ScanSnap S1100 profiles?

Last updated: 4 February 2026
Problem
Your ScanSnap S1100 scan profiles keep reverting to default settings. Changes to resolution, OCR, save location or file naming appear to work temporarily, but later reset without warning. This can happen after restarting the computer, updating ScanSnap Home, switching user accounts, or reconnecting the scanner.
Solution
Profile resets in ScanSnap Home are usually caused by user account switching, permission issues, incomplete shutdowns, or software updates overwriting configuration files. In some cases, cloud sync or backup tools interfere with ScanSnap Home’s local profile storage. By stabilising user context, permissions and shutdown behaviour, you can prevent profiles from resetting unexpectedly.
Step-by-step instructions
Confirm you are always using the same user account
- Log in using the same user account each time you scan.
- Avoid switching users while ScanSnap Home is running.
- Close ScanSnap Home before logging out or switching accounts.
- Restart the computer if profiles behave inconsistently between sessions.
Profiles are stored per user and do not roam automatically.
Check folder permissions for ScanSnap Home data
- Ensure the user account has full read and write access to its home directory.
- On macOS, open System Settings > Privacy & Security.
- Confirm ScanSnap Home has Full Disk Access enabled.
- Restart ScanSnap Home after changing permissions.
If ScanSnap Home cannot write its configuration files, it may revert to defaults.
Avoid forced shutdowns or sleep while ScanSnap Home is open
- Close ScanSnap Home before putting the computer to sleep.
- Avoid shutting down or restarting while ScanSnap Home is actively running.
- Allow the application to close cleanly so settings can be saved.
Profiles may not persist if the application cannot write changes to disk.
Review software updates and first run behaviour
- After updating ScanSnap Home, open the application manually.
- Review scan profiles immediately after the update.
- Reapply any custom settings if required.
- Restart the computer once after major updates.
Some updates reset or migrate configuration data.
Check cloud backup or sync tools
- Identify any cloud backup tools syncing the user profile, such as cloud drive software.
- Temporarily pause syncing and test profile persistence.
- Exclude ScanSnap Home configuration folders from sync if necessary.
Conflicting sync operations can overwrite profile files with older versions.
Export or document profile settings
- Record key profile settings manually.
- Take screenshots of profile configurations for reference.
- Recreate profiles if corruption is suspected rather than editing existing ones.
Recreating profiles is often faster than troubleshooting corrupted settings.
Optional methods or tools
- Dedicated scanning user account
Using a single user account exclusively for scanning avoids profile conflicts. - Local storage preference
Store profiles and scanned files locally rather than in synced folders. - Post-update checks
Make reviewing profiles part of your routine after software updates.
Best practices or tips
- Always close ScanSnap Home cleanly.
- Avoid scanning while switching users or sessions.
- Keep cloud sync away from application configuration folders.
- Restart after updates even if not prompted.
- Keep profile customisation simple and documented.
Repeated profile resets on the ScanSnap S1100 are almost always a software state issue rather than a scanner fault. ScanSnap Home expects stable user context and consistent access to its configuration files. When those conditions are disrupted, it falls back to default behaviour to protect itself from corrupted settings.
By keeping scanning workflows simple, avoiding aggressive syncing and ensuring ScanSnap Home can save settings cleanly, profile resets become rare. Once stable, your customised profiles should persist reliably across restarts and everyday use.
