Hi Tony, I take it you've also checked the ink level is ok?
Troubleshooting print quality issues
One thing that might be worth trying if the printer is out of warranty is soaking the printhead ....
1) Get a pan and put 1/2" of very hot (not boiling) water in the bottom.
2) Next remove all the ink cartridges, then remove the printhead assembly.
3) Gently put the printhead nozzles down in the water and let it soak for five minutes.
4) Remove the printhead and gently dry the electrical contacts.
5) Put the printhead back in the printer and then reinstall the ink cartridges.
