Quick troubleshooting view
A multifunction printer can no longer save scans to a network folder while printing can continue to work.
- password of the scan account was changed
- SMB or incompatible protocol
- share permissions
- Test Account
- Check the path
- Control port
- update the password saved in the printer
- correct folder permissions
- update the firmware if the device does not handle modern SMB
Contextual technician plan
Open the share from a workstation with the same credentials.
Test-NetConnection -ComputerName server -Port 445TcpTestSucceeded should be True for the tested host and TCP port.
The TCP path is open; focus on the application, authentication or protocol layer.
Use a FQDN or IP test to isolate DNS.
The calculated usable capacity should match the actual RAID
If the theoretical calculation matches the controller/OS values, the capacity is explained by the design rather than a fault.
If values still differ materially, preserve the controller layout and investigate hidden reserve, hot spare, mixed disk sizes or filesystem overhead before resizing.
Test TCP port 445 between the device and the server.
Test-NetConnection -ComputerName server -Port 445TcpTestSucceeded should be True for the tested host and TCP port.
The TCP path is open; focus on the application, authentication or protocol layer.
Check routing, firewall/NAT, target address and whether the service is listening.
Ensure that the device supports SMB2/SMB3.

Check routing, firewall/NAT, target address and whether the service is listening.
Repeat the same validation test after the correction and confirm the original symptom is gone. Validate stability before closing the incident.
Before changing configuration, record the current value and a way back.
Escalate if the equipment only supports SMBv1 and no alternative update or deposit method is possible.

Causes probables
- password of the scan account was changed
- SMB or incompatible protocol
- share permissions
- DNS or wrong UNC path
Diagnostic étape par étape
