What should I do if error code E3 appears on my printer display?

Error code E3 means the print carriage inside the printer has stalled. Lift the ink access door, make sure the printhead cover is properly closed and the carriage is not obstructed, and remove any jammed paper or objects blocking the carriage. Then close the ink access door and press the Resume button to continue printing, or press Cancel. Do not open the printhead cover. (Page 8)
