Can a dirty or damaged paper feed roller cause the Epson L3110 paper lamp to blink?

Yes, a dirty or damaged paper feed roller can definitely cause the blinking paper lamp. The rollers are responsible for pulling the paper through the printer. If they are covered in dust, ink residue, or are worn out, they can lose their grip on the paper, leading to jams and sensor errors. You can try cleaning the rollers with a lint-free cloth slightly dampened with distilled water, or consider replacing them if they are damaged.
