I have a hpdeskjet 3420 and the print cartiage stoped moving. What could be wrong?
If the ink cartridge is good, there isn’t much else you can do. HP has some troubleshooting tips, but it could be that you have a major problem, and outside of warranty, you’ll need to replace or upgrade the printer. Landmark recomends laser printers because they are more rugged and dependable, and print a more permanent page at a much lower cost per page.
