My HL-2140 has that option. It’s recommended for heavy weight papers–I tried 130lb and it wasn’t enough. I never thought to try it on lighter paper. When my printer told me my cart was empty and started printing poorly, I hit the magic sequence to tell it that the cart was changed and printing quality went back to normal immediately. Like it was completely faking the poor quality to get me to change the cart. You might try that?
