Setting up your Canon MAXIFY MB5420 wireless connection shouldn't be complicated, but many users encounter roadblocks during the initial configuration or when reconnecting after a network change. This comprehensive guide walks you through every Canon MAXIFY MB5420 wireless setup method—from the standard WPS push-button approach to manual network entry and USB-assisted configuration. Whether you're installing this business inkjet for the first time or troubleshooting a dropped connection, these printer repair steps will get you back online.
Preparing for Wireless Setup
Before beginning the Canon MAXIFY MB5420 wireless setup process, gather your network information and verify your equipment. The MB5420 supports 2.4GHz wireless networks (802.11b/g/n) and requires a stable router connection for optimal performance. Ensure your router's WPS button is accessible, or have your Wi-Fi network name (SSID) and password ready for manual entry.
⚠️ Important: The Canon MAXIFY MB5420 does not support 5GHz-only networks. If your router broadcasts separate 2.4GHz and 5GHz bands, connect to the 2.4GHz network during setup. Attempting to connect to an unsupported frequency will cause repeated connection failures with no specific error code.
Wireless Setup Methods
1
Standard Connection Using WPS Push Button: Power on your MB5420 and press the HOME button. Navigate to LAN Settings > Wireless LAN Setup > WPS (Push Button Method), then press OK. When the printer displays "Press WPS button on access point," press and hold the WPS button on your router for 5 seconds. The printer's Wi-Fi lamp will flash blue during negotiation and turn solid when connected—this typically takes 2 minutes.
2
Manual Network Selection from Printer Panel: If WPS fails or your router lacks a WPS button, use the printer's touchscreen. Press HOME, select LAN Settings > Wireless LAN Setup > Manual Connect. The MB5420 will scan and display available networks. Select your SSID, enter your password using the on-screen keyboard (case-sensitive), and press OK. The printer will attempt connection and display "Connected" or an error code if authentication fails.
3
USB Cable Connection Method: For environments with hidden SSIDs or complex authentication, connect the printer to your computer via USB cable temporarily. Download the latest Full Driver & Software Package from Canon's support site for your operating system. During installation, select Wireless Connection when prompted. The installer will communicate through the USB cable to configure wireless settings, then prompt you to disconnect the cable upon successful configuration.
4
Canon PRINT Business App Setup: Download the Canon PRINT Business app (iOS/Android) to your smartphone or tablet. Ensure your mobile device is connected to your target Wi-Fi network. Open the app, tap Register Printer, and select Auto Search or Manual Search by IP. For first-time setup, choose Printer Setup and follow the guided wizard. The app transmits network credentials directly to the MB5420 via temporary direct wireless connection.
5
Verify and Print Network Configuration: After any setup method, confirm success by printing a network settings page. Press HOME > Setup > Device Settings > LAN Settings > Print LAN Details. Verify that "Connection" shows "Active," the IP address is valid (not 0.0.0.0 or 169.254.x.x), and "Signal Strength" reads 70% or higher. Weak signals cause intermittent printing failures even when initial setup appears successful.
6
Install Printer Drivers on Each Computer: Wireless setup completes only when computers can actually print. Download the MB5420 driver from Canon's website—select either the standard driver or the IJ Printer Driver for network printing. During installation, choose Custom Install > Network Connection. The installer should auto-detect your printer. If not, enter the IP address from your network configuration printout. Test print from each device to confirm two-way communication.

Why does my Canon MAXIFY MB5420 keep losing its wireless connection?
Intermittent disconnections usually stem from router channel congestion, firmware mismatches, or power-saving settings. Access your router administration panel and assign a static IP address to the printer's MAC address. Disable Wi-Fi power saving on the MB5420 through LAN Settings > Other Settings > Power Save. Also ensure your router firmware is updated—older firmware often drops connections with business inkjet printers.
Can I set up the MB5420 wirelessly without the LCD touchscreen?
No—the Canon MAXIFY MB5420 requires its 3.5-inch color touchscreen for initial wireless configuration. Unlike some PIXMA models, the MB5420 lacks a USB-based wireless setup utility that bypasses the panel. If your touchscreen is unresponsive, this indicates a hardware fault requiring professional printer repair or warranty service through Canon's support channels.
What error codes indicate wireless setup failure on the MB5420?
Common codes include E, 2, 6 (WPS timeout), E, 2, 7 (authentication failure), and E, 2, 9 (no network found). For E, 2, 6, reduce distance between printer and router to under 10 feet during setup. For E, 2, 7, re-enter your password carefully—special characters and spaces often cause entry errors. For E, 2, 9, verify your router broadcasts the SSID (not hidden) and operates on channels 1-11 in the 2.4GHz band.
