When you lift up the top including the part with all the buttons, not just the scanner cover, you'll see the door which covers the cartridges. The manual can be downloaded in Adobe Reader format from http://www.retrevo.com/search/v2/jsp/mytrevo/myTrevo.jsp?page=man
The instructions for changing the ink cartridges complete with pictures are on page 48.

yes, that is a carriage jam and not paper, the grinding is from the clean station that gets blocked with dried ink and cant move. you need to open the printer and clean the ink off of the clean station so it can clean properly and not cause a carriage jam.

Pull the black cover open above the paper cassette.

I will provide you with the Manual on your HP Printer below. Just go to the following Link below!

It could be that the ink cartridge of the printer is not properly connected. Make sure that the ink cartridge is seated properly on its slot. Also make sure that the ink cartridge is full.

There is a handle right below the number keys. Once you lift the top part of the machine the ink cartridges scrolls to the middle of the opening. replace accordingly. The ink cartridge numbers are on the lids so you will know which one goes where.
