EPSON PRINTER N-COTTER L-130/210/220 (CHINA)

The Epson Printer N-Cotter (often referred to as the paper eject roller cotter, retaining clip, or roller lock pin) is a specialized small mechanical hardware part manufactured in China. It is designed precisely for Epson L-Series models including the L130, L210, and L220. This small yet vital component secures the paper feed roller wheels (eject rollers) onto the main rotating metal shaft inside the paper output assembly. Made from highly durable, injection-molded industrial plastics, the "N-Cotter" gets its name from its structural layout or slot design, which allows it to clip firmly onto the rod to prevent axial sliding or vibration of the rubber rollers during high-speed printing. If this clip breaks, falls out during a paper jam, or wears down, the rollers will drift out of position, causing immediate paper tracking errors, crooked prints, or constant paper jams right at the exit tray. Replacing this inexpensive Chinese aftermarket part restores the precise mechanical grip needed for flawless, straight paper advancement.
