Canon MAXIFY MB2720 printer not found

When your computer or mobile device can't detect the Canon MAXIFY MB2720, you're stuck before you can even start printing. This "printer not found" error typically stems from network connectivity problems, driver issues, or incorrect printer configuration—especially since this business inkjet model relies heavily on wireless and wired network connections for multi-user office environments. The good news: most Canon MAXIFY MB2720 printer not found issues can be resolved in under 30 minutes with systematic troubleshooting. This guide walks you through proven printer repair steps that our certified technicians use daily.

Network Connectivity Troubleshooting

The MAXIFY MB2720 connects via Wi-Fi, Ethernet, or USB. Network-related detection failures are the most common cause of this error. Before diving into deeper printer support procedures, verify your connection method and rule out basic network problems.

1
Verify Physical Connections: For Ethernet users, check that the cable is firmly seated in both the printer's rear port and your router/switch—the link LED should glow steady green or amber. For wireless setup, press and hold the Wi-Fi button until the power lamp flashes, then release and wait for the Wi-Fi lamp to illuminate steadily. If the Wi-Fi lamp flashes rapidly, the printer hasn't joined your network. Access the printer's LCD panel, navigate to Setup > Device Settings > LAN Settings > Wireless LAN > Wi-Fi Setup, and re-run the setup wizard using your router's SSID and password.
2
Confirm Network Alignment: Your computer and MAXIFY MB2720 must share the same network segment. Print a network configuration page: press the Setup button, select Device Settings > LAN Settings > Print LAN Details. Check the IPv4 address (typically 192.168.x.x or 10.x.x.x). On your computer, open Command Prompt and type ipconfig (Windows) or ifconfig (Mac). Compare the first three octets—they must match. If the printer shows a 169.254.x.x address, it failed to obtain DHCP; restart your router and printer, then check router settings for MAC filtering or access controls blocking the printer.
3
Restart Network Stack in Correct Sequence: Power down your computer, printer, and router. Wait 60 seconds for capacitors to discharge. Power on the router first and wait until all status lights stabilize (usually 2-3 minutes). Next, power on the MAXIFY MB2720 and allow it to complete startup—listen for the print head initialization sounds. Finally, boot your computer. This sequential restart resolves many Canon MAXIFY MB2720 printer not found cases by ensuring proper DHCP lease assignment and Bonjour/mDNS service discovery. After restart, attempt to add the printer through Windows Settings > Bluetooth & Devices > Printers & Scanners or Mac System Settings > Printers & Scanners.

Driver and Software Fixes

Corrupted or outdated drivers frequently cause detection failures even when network connectivity is intact. Canon's IJ Printer Driver and IJ Network Tool are critical for proper communication with the MAXIFY MB2720.

4
Remove and Reinstall Canon Drivers: On Windows, open Settings > Apps > Installed Apps and uninstall all Canon IJ Printer Driver entries and the IJ Network Tool. Download the latest complete driver package from Canon's support site—search for "MAXIFY MB2720" and select your operating system version precisely. Run the installer as administrator and choose "Network Connection" when prompted. The setup utility should auto-detect the printer; if not, select "Search for printers on the network" and enter the IP address from your LAN details printout. For Mac users, remove the printer from System Settings, delete Canon folders from ~/Library/Printers, and install the latest CUPS driver package.
5
Use Canon's IJ Network Tool for Manual IP Configuration: If automatic discovery continues failing, assign a static IP address to prevent DHCP conflicts. Install the IJ Network Tool from Canon's driver package. Launch it, select your MAXIFY MB2720, and click Configuration. Under TCP/IP Settings, change "Get IP Address" to Manual and enter an IP outside your router's DHCP pool (commonly 192.168.1.200-250). Set subnet mask to 255.255.255.0 and gateway to your router's IP. Click OK to send settings, then restart the printer. On your computer, add printer using this static IP address via "Add manually" > "TCP/IP Device" rather than relying on broadcast discovery.
6
Disable Conflicting Software Temporarily: VPN clients, firewall suites, and network monitoring tools can block printer discovery protocols. Temporarily disable Norton, McAfee, Bitdefender, or Windows Defender firewall; add exceptions for CNMNSUT.exe and CNMOP7M.exe (Canon network processes). Disconnect from corporate VPNs during setup—split tunneling often fails with multicast DNS. For users with multiple network adapters (Wi-Fi + Ethernet + VPN virtual adapters), disable all except the one sharing the printer's network in Control Panel > Network Connections, then retry detection. Re-enable security software after successful printer installation.
⚠️ Important: Never download MAXIFY MB2720 drivers from third-party websites—unofficial packages may contain malware or incorrect firmware that permanently disables wireless functionality. Always use Canon's official support portal. Additionally, avoid factory resetting your printer unless all other troubleshooting steps fail, as this erases fax speed dials, network certificates, and custom paper settings that take considerable time to reconstruct.

Frequently Asked Questions

Why does my Canon MAXIFY MB2720 show as offline even when connected to Wi-Fi?

The "offline" status typically indicates a communication breakdown between the print spooler and printer, not necessarily a network failure. On Windows, open Services (services.msc), restart the Print Spooler service, then clear the print queue. Also verify in printer properties that "Use Printer Offline" is unchecked. For persistent issues, delete and re-add the printer using the IP address rather than the WSD (Web Services for Devices) port, which is less reliable with this model.

Can I use USB connection to bypass the Canon MAXIFY MB2720 printer not found error?

Yes—connecting via USB-B cable to your computer provides a direct, network-independent connection. Install the USB driver from Canon's package, and the printer should appear immediately. However, this limits functionality for other devices on your network. Use USB as a temporary workaround for urgent jobs while you resolve the underlying network detection issue for full multi-device printer support.

How do I fix printer detection issues after a router replacement?

New routers often use different SSIDs, security protocols, or IP ranges. The MAXIFY MB2720 retains the old network credentials. You must reconfigure wireless settings: press and hold the Resume/Cancel button until the alarm lamp flashes 17 times, then release to print network settings. Use the Setup > Wireless LAN > Wi-Fi Setup wizard to join the new network. If your new router uses WPA3, the MB2720 may require a firmware update—check Canon's support site for the latest firmware and install via USB if wireless is unavailable.
