How do I optimize copy quality on the HP LaserJet Pro 200 Color MFP M276?

Place your document on the scanner glass or in the document feeder, touch the Copy button on the home screen, then touch Settings and scroll to the Optimize button. You can select from Auto Select (default), Mixed (for text and graphics), Text (mostly text), or Picture (mostly graphics), then touch Black or Color to start copying. (Page 8)
