The scanner unlock can be found on the platen glass area. When you lift up the ADF (auto document feeder) there is a small black plastic slide switch in the lower left. There should be a padlock symbol for locking and unlocking.

Hope this helps.

If the printer driver is not set as "default printer", you can not print. Make sure your Brother machine is set as default printer. If your brother machine is not set as default printer, set it as default printer.

  1. Click Apple Menu and choose System preferences..., click Print & Fax, Print & Scan or Printers & Scanners.
  2. Choose from pull down menu of "default printer".

If the other error message is displayed on Print Queue, check if the LCD display or LED indication of your Brother machine is not showing some error. If an error is displayed, go to the Troubleshooting section and find a solution.


REGISTER THE PRINTER ICON AGAIN

  1. Choose your printer icon.
  2. Click [-] button to delete the printer icon.

If you use the printer via USB connection, reconnect the USB cable or restart the Macintosh or your brother machine.

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart, hopefully without the annoying cannot clean message.OR

Showing scanner error 6


This is an Issue with scanner

To restore the factory-set defaults
On the all-in-one control panel, press Menu.
Use the < or the > button to select Service, and then press .
Use the < or the > button to select Restore defaults, and then press .
The all-in-one automatically restarts.

Note: This procedure clears fax numbers and names that are associated with one-touch keys and speed-dial codes, and deletes any pages that are stored in the memory. The procedure then automatically restarts the all-in-one

You can also trun off the printer, and clean the scanner bed.

If still wont work, call HP (1-800-474-6836) or take it the HP service center.

Regards,
Shrey
