The following section explains how your paper can be damaged by environmental conditions and cause paper jams.
Paper is hygroscopic. Ambient humidity and temperature fluctuations can affect the following physical characteristics of printer paper:
Heating systems and air conditioners remove humidity from the air, and evaporative coolers add humidity to the air. If paper package is left open, paper can lose or gain moisture. Paper that has lost moisture content streaks and smudges when printing.
HP printers are designed to produce high-quality documents when the printer paper meets the printer's specifications.
As paper loses and gains moisture, its physical characteristics can change, and the paper warps or gets wavy. Feeding warped or wavy paper into the printer results in paper jams.
