Figure : Technique for flexing the paper stack
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.
5. Make sure the tray is not overfilled by checking the stack-height markings inside the tray.
If it is overfilled, remove the entire stack of paper from the tray, straighten the stack, and
then return some of the paper to the tray.
The following images show examples of the stack-height markings in the trays for
various printers. Most HP printers have markings similar to these. Also make sure that all
sheets of paper are below the tabs near the stack-height marks. These tabs help hold the
paper in the correct position as it enters the printer.
