Paper problems

First thing you need to do Turn off the printer and Open the rear access door or cleanout area as we call that (back door) and clean all the rollers on the back. make sure also that you are using the deskjet paper and if you put 20 pages of paper on the paper tray make sure to fan it before you put it in. the alarming sounds or blinking on the printer indicates that the paper is jamming on the printer

-The ink is normal to move to center or left to right, But if you open the printer access door the ink or the printhead should stay on the middle for you to able to replace the ink cartridges and remove the printhead
