When a multifunction device stops scanning to a folder on the PC, the cause is usually a changed IP address or password, missing share permissions, the “Public” network profile, or an outdated SMB version in the device. Current Windows versions block insecure connections that older scanners still use. A firmware update for the device usually solves this better than switching off security settings.
1. Read the error on the device
The display or transmission report often points the way: “connection failed” suggests path or network, “login failed” suggests user or password. Note the message before changing anything.
2. Check the path and IP address
The target is usually a path like \\PC-NAME\Scans or \\192.168.178.20\Scans. If the PC got a new IP address after a router restart, the scanner can no longer find the folder. A fixed address for the PC helps for good: the router can always give it the same IP address.
3. Set the network profile to “Private”
If the network is set to “Public” in Windows, shares are blocked. Open Settings > Network & internet, select your connection, and set the network profile type to “Private”. Then check that file and printer sharing is turned on.
4. User account and password
- 1Create a separate local user account with a password for the scanner instead of using your personal account.
- 2By default, Windows does not let accounts without a password sign in over the network.
- 3If you sign in with a Microsoft account, the password of that account applies, not the Windows PIN.
- 4Enter user name and password again in the device’s address book if the password has changed.
5. Check the share and permissions
Right-click the scan folder, open Properties > Sharing, and share it with the scanner account with read and write access. On the “Security” tab, check that the account may write there as well.
6. SMB version and device firmware
Many older scanners only speak the old SMB1 protocol, which Windows no longer installs for security reasons. Newer Windows versions also block insecure guest access and require signed connections more often. Do not switch these protections off. Look for a firmware update for the device that supports SMB2 or SMB3 instead.
7. Alternatives when the device is too old
If the device does not support a current SMB version, “scan to email” or scanning to a network storage device (NAS) is often the cleaner solution. For email, many providers require a separate app password for the device.
