My scanner does not connet to the network. (It errors out even after setting up network settings on the scanner device.)

Please confirm the following methods.

• Confirm IIS Manager to see if the NX Manager's application pool and site (NmXXXX) are down.
  
  
• Check if "SQL Server (NXMANAGER)" is stopped in Windows service. If it is stopped, start it.
  
  

• Check that the following communication (ports) are not blocked by the firewall. If they are blocked, refer to your firewall documentation and change the settings so that communication can be established over those port numbers.

  Function	Port number (*1)	Protcol Number
  Scanner connection	20447 (HTTP/HTTPS)	6(TCP)
  Browser connection	10447 (HTTP/HTTPS)	6(TCP)
  REST API linkage	30447 (HTTP/HTTPS)	6(TCP)
  Web Scan linkage	40447 (HTTP/HTTPS)	6(TCP)

  *1:	Those port numbers were specified during installation of NX Manager or set with IIS. Refer to PaperStream NX Manager User's Guide  - "Changing the Firewall Settings".
