Hello and thank you for choosing JA for your support needs. Sorry for the issue. Are you following these steps to fix it Sir or Madam?
Sir or Madam, this is the first step. Many people do not do that. Now, do you have a flashlight and canned air around?
Ok, you can use a Vacuum Hose Madam. Now where in the World are you? In the US or elsewhere?
Ok. Please go and acquire this;
Martin Yale Rubber Roller Cleaner & Rejuvenator - PRE200
This can be found at Staples, Office Depot or Best Buy. It is about $10. This is used to spray the rollers and all rubber surfaces in your printer. This will also lubricate the rollers. Then the Vac and Flashlight is used to seek and remove any stray pieces of paper or any stray objects with in the printer.
As I am on the East Coast, it is still early enough where you are to purchase the Yale product.
