HP Color LaserJet Enterprise M751n Laser Printer - Manual (Page 131)

NOTE: Fanning the paper introduces static electricity. Instead of fanning the paper, flex the stack by
holding it at each end and bringing the ends up to form a U shape. Then, rotate the ends down to reverse
the U shape. Next, hold each side of the stack of paper, and repeat this process. This process releases
individual sheets without introducing static electricity. Straighten the paper stack against a table before
returning it to the tray.

2. Use only paper that meets HP specifications for this printer.
3. 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.
