¶ Introduction
The 22 IDEX V4 printer supports Ethernet connectivity for reliable, high-speed wired access to the web interface. Ethernet offers stable connections, faster file transfers, and immunity to wireless interference compared to WiFi.
This manual guides you through connecting your printer via Ethernet using the touchscreen interface. Simply connect the cable, run the setup macro on the touchscreen, and the printer will automatically configure itself and display the connection information.
You can choose between:
- Regular Ethernet Mode - Connect to your network router or switch (automatic or static IP)
- Ethernet to PC Mode - Direct connection to a single computer
Note: Ethernet requires Cat5e or better cable. Ensure you have appropriate cable length to reach from printer to router, switch, or computer.
¶ Ethernet Connection Options
The Enable Ethernet Mode macro offers three configuration options:
¶ DHCP (Automatic)
Easiest option - Router automatically assigns IP address.
Use when:
- You have a network router or switch
- You want multiple devices to access the printer
No manual configuration needed.
¶ Static IP (Manual)
Fixed IP address - Useful for advanced network configurations.
Use when:
- Your network requires fixed IP addresses
- You need consistent printer addressing
Requires: IP address, subnet mask, and gateway.
¶ Ethernet to PC Mode
Direct connection - Point-to-point connection to one computer.
Use when:
- You don't have a router or switch
- You want isolated connection to single computer
Requires: Computer configured with static IP 192.168.1.51.
Important: Ethernet to PC mode requires configuring your computer's network settings first.
¶ Prerequisites
For Regular Ethernet Mode:
- Ethernet cable (Cat5e or better)
- Network router or switch with available port
- DHCP enabled on router (default on most routers)
For Ethernet to PC Mode:
- Ethernet cable (Cat5e or better)
- Computer with Ethernet port (or USB-to-Ethernet adapter)
- Administrative access to change network settings
Note: You cannot use Ethernet and WiFi simultaneously. Enabling Ethernet automatically disables WiFi.
¶ LED Status Indicators

| Can't connect after restart | Verify cable connected, network equipment on |
¶ Cannot Access Web Interface - Wrong Subnet (MOST COMMON)
Symptoms:
- Green LEDs (test successful)
- Cannot access printer via IP address
Warning: This is the most common issue. Your computer and printer must be on the same subnet!
Why this happens:
For devices to communicate, the first three numbers of the IP address must match.
Examples:
✅ Works - Printer: 192.168.1.150, Computer: 192.168.1.100
❌ Doesn't Work - Printer: 192.168.1.150, Computer: 192.168.0.100
Solution:
-
Check your computer's IP:
- Windows: Command Prompt >
ipconfig - macOS: System Preferences > Network > TCP/IP
- Linux: Terminal >
ip addr
- Windows: Command Prompt >
-
Compare IPs - First three numbers must match
-
Fix mismatch:
- Regular Ethernet: Restart network adapter or connect to correct network
- PC Mode: Verify computer is set to
192.168.1.51
¶ Red LEDs During Test - Connection Failed
What happens:
- Printer tests connection
- Test fails
- Automatically reverts to previous mode
Solutions:
- Check cable - Firmly seated at both ends
- Try different cable - Use Cat5e or better
- Check equipment - Router/switch powered on
- Try different port - Test another port on router/switch
For PC Mode:
- Verify computer IP is
192.168.1.51 - Restart computer after changing network settings
