If your Brother HL printer is cable connected to your network and suddenly appears offline the fix could be exactly like you’d expect – simple.
Have you first checked these points:
- Power is on and the LCD panel on the front is displaying something (other than an error message),
- The ethernet cable hasn’t been damaged or tampered with,
- It is showing as connected to the LAN (light on network hub/switch is on and shows activity),
If everything appears normal and it was working fine (nothing has been changed), then check this one simple point: that LAN is enabled in the printer settings.
Press the OK button (to wake it up, if it wasn’t asleep), press the up/down arrow button to ‘Network’. Press OK.
Use the up/down buttons to ‘Wired LAN’. Press OK
Then: ‘Wired Enable’ – it is likely disabled. Press OK to enable/disable.
Wait 20sec. Check your local computer to see if the printer is now back online.
