Several factors can lead to paper jams in HP printers. Misaligned or overloaded paper trays are common culprits. Using incorrect paper types or sizes can also trigger jams. Worn-out or improperly adjusted rollers may fail to feed paper smoothly. Foreign objects, like staples or torn pieces, can obstruct the paper path. Additionally, dusty or humid environments can affect paper integrity. If the printer is not kept clean and well-maintained, accumulated debris may cause jams.
