Why won't the photo paper feed into the printer?

I am having problems with my G600 printer dock picking up the paper and running it through the printer. I have only printed a little over 200 pictures with the unit and this problem just started this week. I purchased the printer on March 15,2007 at Best Buy so I know the warranty has expired. I have tried many combinations and adjusting the tray that fits into the printer and feeds the paper. Have other people had this problem? Do I need to purchase a new feeder tray or what? I hate to think I have spent $119.99 to print just 200 pictures and can't figure out how to get this problem solved. I never put too many sheets of photo paper in the feeder tray and have followed all instructions carefully. It worked fine for a long time and all of a sudden has decided to give me trouble.
Help!
