Question about Brother MFC-5440CN All-In-One InkJet Printer
Suddenly, no matter what button on my MC-5440CN I press, I get the figure 7 appearing on the LCD and nothing else happens.
I can operate all functions (print, fax, scan and copy) from my computer, but the manual options (including Start, Finish, Power Save - everything) only give me a "7"
I have tried disconnecting, rebooting etc but the machine will only work from the PC, not from the control panel.
Your control panel has gone bad, or you have a stuck key.
Make sure all your keys move freely. If theyp're good, call your local service centre and get the price for a key keyboard assy. They're not expensive and are fairly easy to replace.
