6 TROUBLESHOOTING FOR NETWORK CONNECTIONS
Cannot locate the equipment with Local Discovery
Problem Description
Local Discovery cannot detect the equipment.
Corrective Action
The equipment is normally located automatically by SNMP. When the TWAIN driver, File Downloader, Address Book Viewer, Backup/Restore Utility, or Remote Scan driver cannot automatically discover the equipment over the network, the most likely cause is limitations of the protocols supported by the computer. In some cases, you need to add or update network components; however, first see the checklist below to fix the problem.
