What are some common causes of carriage errors ('002') on the Epson LX 310, and how can I troubleshoot them?

Carriage errors ('002') can be caused by obstructions in the carriage path, a faulty carriage motor, or a damaged carriage belt. Inspect the carriage path for any debris. Try manually moving the carriage to see if it moves freely. Listen for unusual noises from the carriage motor. If the belt appears loose or damaged, it may need replacement. These issues often require professional servicing.
