Question about Brother MFC 420CN All-In-One InkJet Printer
My printer was ok but this morning after printing a lot of papers a message Machine error A7 appeared and the printer was totally out of order while the light always is on-off even though I turn machine off. I restart again but I still get the same message. I try to fix it but it doesn't work. Can anybody help me with this problem? Thank you very much.
A7 says that the scanner information in the eeprom is corrupted. The scanner is the wrong type. You will need a shop to do the eeprom clear in the diagnostic mode.
