We see no difference between the original and printed copy. I noticed that get copies of the printed large document when you use the black copy. What is the technical difference between the black copy function and the function of scan (Document to the printer setting) in HP-each when you print a black and white document? Sometimes I have a HP Photosmart C6280 but imagine a similar software is used in most HP AIOs.

This ensures that the printer is full on. I want you to try a power reset and make sure that the printer is plugged directly into the wall, avoiding bars power and surge protectors.

I say this because when you print from your computer, normally the ink colors mix to create a composite black, and when you print copies, it's only the black ink cartridge that is used. I will do my best to help! I might be far away but I suspect that there could be a problem with the printhead and it printing black ink. Welcome to the HP community understand that your 3520 Deskjet is no copy making more correctly however, you can print and scan without a problem.
