HP 220240 - Manual (Page 42)

Here are some general guidelines about the paper used in the printer.
• Use only high-quality paper such as the papers listed in Appendix B.
• Avoid using any paper that is creased, folded, punched, clipped, stapled,
or damaged.
• To prevent paper curl (a curved bend in the paper), stack the paper on
a flat surface for storage.
• Prevent changes to the moisture content of the paper by storing it
properly and rewrapping unused portions. Do not store paper directly
on the floor.
Complete specifications for print media are in Chapter 5. For more detailed
information, consult the Digital Laser Printers Guide to Paper and Other
Media (see Appendix B for ordering information).
