Epson 接続診断ツール 3.4

Epson 接続診断ツール is a troubleshooting utility designed to identify and resolve connection problems between a Windows PC and Epson printers/scanners. It automatically checks how your device is connected (USB, wired LAN, or Wi‑Fi), looks for common causes of “printer not found” or “offline” errors, and offers clear, step‑by‑step guidance to restore communication.

Key capabilities:

• Detects connection type and device status, including driver installation and print spooler state
• Scans for network issues such as incorrect SSID/password, IP address conflicts, and weak Wi‑Fi signal
• Flags firewall/antivirus settings that may block printer discovery or scanning
• Provides recommended fixes and simple pass/fail results, with optional logs you can share with support
• Helps reconnect the printer to your router or prompts driver reinstallation when needed

Typical use cases:

• PC cannot find the Epson printer/scanner over Wi‑Fi or Ethernet
• Printer shows as offline or jobs are stuck in the queue
• USB printer not detected after cable/port changes
• Intermittent connectivity after router or network updates

Notes:

• Intended primarily for Windows environments and for Epson devices; feature availability may vary by model and OS.
• Download from your regional Epson support site and run with administrator permissions for best results.
• The tool reads local network/printer settings; diagnostic data is only shared if you choose to submit logs to support.
