Let's try the below steps.
Remove all paper from the output tray.
Remove Tray 1 from the printer.
Tap a stack of plain paper on a flat surface to align the edges.
With the input tray outside of the printer, load the stack of paper.
Make sure all the paper in the stack is the same size and type. Never load mixed types of paper in the tray. The printer can process only one type of paper at a time.
Make sure the paper height does not exceed the dotted yellow lines on the sides of the tray.

Adjust the paper width and length guides. The paper should rest against the end of the tray, and the guides should rest against the edges of the paper.
