What are the common causes of an E3 error in the HP 585 series?

The most common causes for an E3 error on an HP Smart Tank 585 printer include paper jams (often due to crumpled, incorrect size, or too much paper loaded), foreign objects inside the printer (like staples, paper clips, or even small toys), issues with the printhead carriage movement (it might be stuck or obstructed), or rarely, a sensor malfunction that falsely detects a jam. Using non-recommended paper types or overloading the paper tray can also contribute to jams.
