Canon Canon imageCLASS LBP246dw 40 ppm Wireless Duplex Mono Laser Printer MECH-WIFI Error Fix: Wi-Fi Connectivity Issues — Printer Offline or Not Found

Error code MECH-WIFI on the Canon Canon imageCLASS LBP246dw 40 ppm Wireless Duplex Mono Laser Printer means: Wi-Fi Connectivity Issues — Printer Offline or Not Found. The printer drops off the Wi-Fi network, shows as "offline" on computers, or cannot be discovered by mobile devices. Canon imageCLASS printers support 2.4 GHz Wi-Fi only on most consumer models (some newer models support both bands). Verify the printer has a valid IP address by printing a Network Configuration page (hold the status/info button). If the IP shows 0.0.0.0 or 169.254.x.x, the printer is not connected to your network. Run the Wireless LAN Setup from the printer's network settings menu. For reliability, assign a static IP to the printer through your router's DHCP reservation settings. Ensure the printer is not too far from the router. Mesh Wi-Fi systems can cause issues — configure the router to keep the printer on 2.4 GHz.
