Good morning! my name is***** see that you have been waiting quite a while for an answer. I am sorry about that. I will do my best to help you with this problem. There could be a couple of different causes of this problem. If you are printing a small photo, it can be more difficult for the printer to pick it up. It is important to make sure that the photo paper is inserted correctly, and that you have selected the correct size in the printer dialog box. if you're sure that everything is correct and you continue to have problems, it is likely that your Paper Feed Rollers may need cleaning. I can provide detailed instructions for using the printer utility on your computer to run the roller cleaning utility once I know what operating system you have.
