Hi! @pedrochino, Welcome to HP forums.

I understand you are getting out of paper issues with your printer.

Don't worry I'll try to help you out.

Did you make any changes to your printer?

Have you tried checking with a different brand paper?

Please try the steps recommended below.

The type and condition of paper can affect the way your printer picks paper. The edges of low-quality paper that have absorbed moisture might curl or lift the sheet so the paper does not feed into the printer.
Use these steps to check and then restack your paper.
Remove the stack of paper from the paper tray.
Use 25 sheets of new plain white paper to form a stack of paper.
Tap the stack of paper on a flat surface to align the edges.
   NOTE:
Do not fan the paper by running your fingers through the paper stack.
Insert the stack of paper into the paper tray.
Slide in the paper width guide to the edge of the paper stack. Make sure that the guide rests gently against the paper stack and does not bind it.
Try printing again.
If the issue is not resolved, try loading different brands of paper and different types of paper, one type at a time, into the printer and then try printing again.

Let me know if this helps!

Have a great day ahead! 🙂
