3. Verify that the humidity in the room is within specications for this printer, and that paper is being stored in

In high-humidity environments, paper at the top of the stack in the tray can absorb moisture, and it might
have a wavy or uneven appearance. If this happens, remove the top 5 to 10 sheets of paper from the stack.
In low-humidity environments, excess static electricity can cause sheets of paper to stick together. If this
happens, remove the paper from the tray, and ex the stack as described above.
4. Use paper that is not wrinkled, folded, or damaged. If necessary, use paper from a dierent package.
