Make sure you are regularly changing captops and wipers... Also, if you've had your printer more than 2 years have your dealer run a pec-report on your machine (they will send you a link by e-mail and then just e-mail the report back to them). This report will let them know of any issues you may not be aware so you can be proactive in addressing any problems and it will let you know the shot count of the print heads, the scan motor hours, etc.
