Hi, I'm Sudipto. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
Do you get any error message on the printer or PC, when you try to print something?
Do you face this same problem, when you try to make copies also?
Can you detach the that tray from the printer?
OK, detach the tray and then, check the feed rollers, if they are working correctly or not then, clean them with a damp cloth and after that try to print.
OK, rollers are moving freely on that tray?
Sorry for the late reply, I am doing some research on this problem and the only solution, which I find out is, either you have to replace the roller assembly or try to free the movement of that roller. Can you try to do it by putting some machine oil
Is it working now?
