Verify that the humidity in the room is within specifications for this printer, and that paper is being stored in unopened packages. Most reams of paper are sold in moisture-proof wrapping to keep paper dry. 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 flex the stack as described above. 4. Use paper that is not wrinkled, folded, or damaged. If necessary, use paper from a different package. 176 Chapter 10 Solve problems ENWW
