How to Clean the Print Head on an MFC

1. Touch the ink menu icon -- the image with four ink level bars -- on the Brother MFC-790CW touch screen to open the Ink menu.
2. Select the 'Cleaning' option and then select the ink cartridge that isn't printing correctly -- 'Black,' 'Color' or 'All' -- to start the cleaning process.
3. Wait for the unit to clean the printhead. When the original screen reappears, touch the ink menu icon again, select 'Test Print' and then 'Print Quality.' Press the 'Color Start' key to print a Print Quality Check sheet.
4. Check the patterns that print for lines or voids. If you don't see any print issues, select 'Yes' and then press the 'Stop/Exit' key to exit the menus. If print issues still exist, select 'No' twice, press the 'Color Start' key to restart the cleaning process and then press 'Color Start' again when it ends to print and check another sheet.
