Okay, im assuming the brother all in one in the picture is what you're on about...right?!? anywayz :) basically i think it is because you have got "faxes saved in the memory" it sounds weird but the scanner locked is coming up because the scanner is not going back to its home position. if there are faxes in its memory, it means that the memory has not been cleared. to check press menu/set 9,0,1 - if the screen says "No data" means that the memory has been cleared and i don't know what to do!! if it says "Enter fax.no" means that there are faxes in the memory, in this case, the fax must be cleared of memory, (if you need the faxes, you must save them before proceeding) turning it off clears memory apparently but im assuming you've tried that countless times.Turn off the machine's power switch and then on again. If the error message continues, leave the machine for several minutes and try it again. the MFC-7820 can store memory for up to 4 days, so watch out if you have a 7820. apparently this will resolve the issue and the message should go away, hence the scanner returning to its home position!! hope this helps

Error light on and saying scanner error


Hi!

Open the Lid for scanner, check for a switch on the side for Scanner Lock. Try to switch it to unlock position and retry booting up Printer. That should take care of scanner error message.

Hope this helps. Cheers!

Please help... Says "scanner locked"


Power off the printer. There is a green tab located in the paper output section of the printer. If you side your hand below the keypad on the left side you will feel the tab sticking down. Pull the tab towards the front of the printer to unlock the scanner. Then power on the printer, this should remove the scanner locked message. Hope this helps you.

The error message is saying the scanner is locked i took the steps to unlock it but i still get the same message


If you opened the lid in the same manner as you would to replace the ink cartridges and made sure that the switch on the right side underneath the lid was in fact unlocked, turned off the unit, waited a moment (up to 60 seconds) and turned the unit back on, but still receive the message saying that your scanner is locked, then you will need to use a Phillips screwdriver to remove the top cover and make sure that the scanner head is not somehow jammed. Usually you can hear the gears and motor spin up when the scanner head is unlocked. If you cannot, you may have a bad scanner head.

Many scanners contain a scanning head lock to keep the scanning head from moving during shipping. This may still be still be in the lock position. All scanners are different but check the documentation on how to remove the head lock.

2. Lift the scanner cover.

3. Toggle the transportation lock five times, ensuring that it is in the unlocked position, towards the back of the scanner.

4. Turn on the printer, and the error should be cleared.
