Does this happen with all sizes of paper? Are you able to copy?
Clean the paper feed rollers
Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again.
Turn off the printer, and then disconnect the power cord and any other cables.
WARNING:
You must unplug the power cord to move the carriage by hand and reset the paper feed mechanism without the risk of electrical shock.
Raise the input tray.
Lift and hold the input tray shield.
Look down through the open input tray and find the gray paper pick rollers. You might need a flashlight to illuminate the area.
Lightly dampen a cotton swab with water, and then squeeze any excess liquid from the swab.
Press the swab against the rollers, and then rotate them upward with your fingers. Apply a moderate amount of pressure to remove dust or dirt buildup.
Lower the input tray shield.
Allow the rollers to dry completely (approximately 10 minutes).
Reconnect the power cord and any other cables, and then turn on the printer.
Try to print.
