So far I am getting the light issue in my printer but with the help of dell printer error 016-302 helped me to get the solution.
I’m using Dual Extruder 3D Printers for Better and Quicker Printing and did not face any light issue. If you’re still facing any light issue, you should look for a new printer. It is also suggested you to use a double extruder since they provide a quick and better printing.
