When your Brother MFC-J6935DW AirPrint not working, it disrupts your entire workflow—especially if you rely on iPhones, iPads, or Macs for quick wireless printing. This INKvestment Tank all-in-one printer supports Apple AirPrint natively, but network misconfigurations, firmware gaps, or mDNS discovery failures often block the connection. This guide walks you through proven printer repair and troubleshooting steps to restore AirPrint functionality without unnecessary frustration.
Common Causes of AirPrint Failure on the MFC-J6935DW
Before diving into fixes, understand why Brother MFC-J6935DW AirPrint not working occurs. The MFC-J6935DW broadcasts its AirPrint service via Bonjour/mDNS over your Wi-Fi network. If your router blocks multicast traffic, your iOS device can't discover the printer. Outdated firmware, disabled IPv6, or the printer connecting to a guest network instead of your main LAN also break AirPrint. Even temporary IP address conflicts can hide the printer from Apple devices.
Step-by-Step AirPrint Troubleshooting
1
Verify Network Connection on Printer: On the MFC-J6935DW touchscreen, press Menu → Network → WLAN → TCP/IP to confirm the printer received an IP address in your router's range (typically 192.168.x.x or 10.x.x.x). If it shows 169.254.x.x, the printer failed to obtain a valid IP—reconnect to Wi-Fi or restart your router. The printer and Apple device must share the exact same network subnet for AirPrint discovery.
2
Update Printer Firmware to Latest Version: Brother resolved several AirPrint compatibility issues in firmware updates post-2021. Access the Brother support site from a computer, search "MFC-J6935DW firmware," download the latest .lfu file, and transfer it via USB or through the Web-Based Management interface. Navigate to the printer's IP address in a browser → Administrator → Firmware Update → upload the file. The printer will restart automatically—do not power off during this process.
3
Enable AirPrint and Bonjour Services: Open the MFC-J6935DW Web-Based Management by entering its IP address in any browser. Log in with the default password (found on the printer's network config page). Navigate to Network → Protocol → ensure AirPrint and Bonjour are both set to Enabled. If disabled, activate them and click Submit. Restart the printer completely—full power off for 30 seconds, then restart—to force service re-advertisement on the network.
4
Check Router Settings for Multicast/mDNS: Log into your router's admin panel and locate settings for Multicast, IGMP Snooping, or AP Isolation. Disable AP Isolation (also called client isolation) entirely—this feature blocks device-to-device communication and directly causes Brother MFC-J6935DW AirPrint not working symptoms. Enable multicast/IGMP if available. For mesh systems like Eero or Orbi, ensure the printer connects to the primary node, not a satellite with NAT enabled.
5
Reset Network Settings and Reconfigure: If AirPrint still fails, perform a network reset. On the touchscreen: Menu → Network → Network Reset → confirm. Reconnect to Wi-Fi using Setup Wizard, entering your SSID and password manually if auto-discovery fails. Assign a static IP address outside your router's DHCP range to prevent future IP conflicts—this stabilizes printer support connectivity long-term. Re-add the printer in iOS Settings → Printers & Scanners.
6
Test Alternative Discovery Methods: As a diagnostic step, install Brother iPrint&Scan from the App Store. If this app finds the MFC-J6935DW but AirPrint doesn't, the issue is specifically mDNS/Bonjour advertisement. Try printing from a Mac using System Settings → Printers & Scanners → + → IP tab → Protocol: AirPrint with the printer's IP address. Success here confirms the printer functions; the fix then lies in iOS network discovery, often resolved by restarting your iPhone/iPad and ensuring Private Wi-Fi Address is disabled for your network.
⚠️ Important: Never factory reset your Brother MFC-J6935DW unless all network troubleshooting fails—this erases all settings, registered apps, and fax configurations. Always document your current network settings before any reset. Additionally, avoid using WPS push-button setup on routers with band steering enabled, as the printer may connect to 5GHz while your Apple device remains on 2.4GHz, breaking AirPrint discovery despite both being "on Wi-Fi."
Frequently Asked Questions
Why does my iPhone say "No AirPrint Printers Found" for my MFC-J6935DW?
This error typically means Bonjour/mDNS packets aren't reaching your iPhone. The printer and iPhone must be on the same network without client isolation enabled. Restart both devices, verify the printer's IP address is valid, and check that AirPrint is enabled in the printer's web interface. Enterprise networks with VLANs or wireless guest policies often block this traffic—contact your IT administrator if on a work network.
Does the Brother MFC-J6935DW support AirPrint on both 2.4GHz and 5GHz Wi-Fi?
Yes, but AirPrint discovery requires both devices on the same frequency band or a router that properly bridges multicast between bands. Some older routers and extenders fail to forward mDNS across bands. For reliable printer repair results, connect the MFC-J6935DW to your main router's 2.4GHz band if you experience intermittent AirPrint availability, as 2.4GHz has better range and penetration through walls.
Can I fix printer AirPrint issues without a computer?
Partially. You can verify network settings, restart the printer, and reinstall Wi-Fi directly on the MFC-J6935DW touchscreen. However, firmware updates and detailed protocol configuration (enabling AirPrint/Bonjour) require accessing the Web-Based Management interface, which needs any device with a browser—even a smartphone. For comprehensive tech support and firmware fixes, temporary computer or tablet access significantly speeds resolution.
