We had printed out about 6 sheets of paper, when suddenly the paper quit feeding. Even though we had paper in the tray, we kept getting 'out of paper' error message. At first, we thought it was because we needed a new Black ink cartridge. But after installing the cartridge, same problem cropped up. It seems the paper is not being pulled in to print. We adjusted the paper guide; used canned air to flush out dirt; tried to clean the paper roller on bottom near where paper sits, but hands are too big to reach inside tiny space. We opened rear panel to check for paper jam, nothing there. Is it a mechanical or electrical issue? We've had this printer at least 5 years, really don't want to spend $$$ to replace it right now.
