Your Canon MAXIFY iB4120 IP address is essential for network printing, remote management, and resolving connectivity problems. Whether you're setting up the printer for the first time, reconnecting after a router change, or troubleshooting a lost connection, knowing how to find, configure, and troubleshoot this network identifier will save you hours of frustration. This guide walks you through every method to locate and manage your Canon MAXIFY iB4120 IP address with clear, actionable steps.
Finding Your Canon MAXIFY iB4120 IP Address
The fastest way to resolve network printing issues is to verify your printer's current IP configuration. Here are the most reliable methods to locate this information directly from the printer or your computer.
1
Print the Network Configuration Page: On the Canon MAXIFY iB4120, press and hold the Resume/Cancel button (the triangle inside a circle) until the power lamp flashes 15 times, then release. The printer will print a detailed network configuration sheet showing the IPv4 address, subnet mask, default gateway, and MAC address. Check the "TCP/IP" section for your active Canon MAXIFY iB4120 IP address.
2
Check the LCD Display Menu: Press the Setup button (gear icon) on the printer's control panel. Navigate to Device Settings > LAN Settings > Confirm LAN Settings > WLAN Setting List or Wired LAN Setting List. The IP address will display on screen. If the display shows "0.0.0.0," the printer hasn't obtained an IP address from your router and requires further troubleshooting.
3
Use the Canon IJ Network Device Setup Utility: Download this free tool from Canon's support website for Windows or Mac. Install and run the utility—it automatically scans your network and lists all Canon printers, including your MAXIFY iB4120, with their current IP addresses, connection type, and status. This is especially helpful if you can't physically access the printer.
Fixing Canon MAXIFY iB4120 IP Address Problems
When your printer's IP address changes unexpectedly or disappears entirely, print jobs fail and the printer becomes unreachable. These troubleshooting steps address the most common causes and provide lasting solutions.

Assign a Static IP Address: Log into your router's administration panel (typically at 192.168.1.1 or 192.168.0.1) using a web browser. Navigate to DHCP reservations or Address Reservation. Locate your Canon MAXIFY iB4120 by its MAC address (found on the network config page), then assign a fixed IP address outside your router's automatic DHCP range—for example, if DHCP assigns 192.168.1.100-199, use 192.168.1.50. This prevents the Canon MAXIFY iB4120 IP address from changing when the printer reconnects.
5
Reset the Network Settings and Reconnect: On the printer, press Setup > Device Settings > Reset Settings > LAN Settings Only > Yes. After restart, run Wireless LAN Setup or Wired LAN Setup again from the Setup menu. For wireless, select Standard Setup, choose your network name (SSID), and enter your Wi-Fi password precisely. For wired connections, simply reconnect the Ethernet cable—the printer should obtain a new IP address automatically via DHCP.
6
Update Printer and Computer Configuration: If you previously installed the printer using its IP address, Windows or Mac may still reference the old address. Open Devices and Printers (Windows) or System Settings > Printers & Scanners (Mac), remove the old printer instance, then add it fresh using the new Canon MAXIFY iB4120 IP address. Alternatively, use the Canon IJ Printer Assistant Tool to update the port settings to match the current IP without full reinstallation.
⚠️ Important: Never assign a static IP address within your router's DHCP range, as this causes IP conflicts where two devices claim the same address. Additionally, avoid using the printer's default IP (typically 169.254.x.x) for manual configuration—these self-assigned addresses only work for direct computer-to-printer connections without internet or network access.

Why does my Canon MAXIFY iB4120 IP address keep changing?
Your router's DHCP server automatically assigns IP addresses with expiration dates (leases). When the lease renews, the router may assign a different address—especially after power outages or if many devices connect. The permanent fix is reserving a static IP in your router settings or configuring a manual IP directly on the printer through Setup > Device Settings > LAN Settings > Other Settings > TCP/IP Settings.
Can I connect to my Canon MAXIFY iB4120 using its IP address for mobile printing?
Yes, but Canon's mobile apps typically use automatic discovery rather than manual IP entry. For Canon PRINT Inkjet/SELPHY app troubleshooting, ensure your phone and printer share the same network. If discovery fails, verify the Canon MAXIFY iB4120 IP address is reachable by pinging it from your phone using a network utility app. Some third-party print apps and enterprise environments do require direct IP configuration.
What should I do if the network configuration page shows no IP address?
This indicates a complete network communication failure. First, confirm physical connections—Ethernet cables seated firmly, Wi-Fi indicator lit steadily (not flashing). For wireless, move the printer within 10 feet of your router during setup. Check if your router blocks unknown devices (MAC filtering) or operates on unsupported frequencies—the MAXIFY iB4120 supports 2.4GHz networks only, not 5GHz standalone. As a last resort, perform a full factory reset: Setup > Device Settings > Reset Settings > All Data > Yes, then reconfigure from scratch.
