The main reasons for the Brother Printer paper feed not working is because the paper is jammed in the machine or the paper tray was not inserted properly. You can refer to the suggestions below to fix the error and try printing a fresh document:
• Make sure the paper is loaded properly and the support flap is unfolded
• Gently clean the paper pick-up roller using isopropyl alcohol
• Check that only one type of paper is loaded in the Brother Printer paper feed
• Avoid using paper that is damaged, wrinkled, or torn or curled
If you find that the paper feed still does not work you can call the customer service Brother printer and ask for technical assistance.
