Seems like the cartridge head is jammed. You can take the cartidge out and put the head for like 5 minutes in warm water then clean it gently with some tissue paper, hopefully this shall solve your problem.

you printer need a proper cleaning, please clean your printer properly with an air blower because an small or very tiny peice of paper seems to be stuck in the print roller or paper loader assembly, if that does not work, pls get your paper loader, roler or paper try checked by an printer technitian, you might also have to change your sensor assambly board.

If after these the situation is the same ..you should change the print-head cause his lifetime is over..

when you connect your printer make sure the cables are in working order and check that they are connected correctly use your manual that came with the Printer to make sure you are starting it correctly(turning it on correctly) then run the CD-Rom and follow the prompts to install, making sure you download the latest drivers if the ones on the CD that came with ur Printer is no good.
you may have to un install first and reinstall it make sure you take the time it takes to install it correctly first time and no short cuts or this could be your problem. (mostly with printers it is driver problems that prevents them from working correctly.
