Disk Encoder For Epson L110 | L210

The disk encoder for the Epson EcoTank L110 and L210—frequently designated as the timing disk or round PF (Paper Feed) encoder wheel—is a transparent circular plastic film that mounts directly to the main paper feed roller axle shaft. As the shaft spins, thousands of microscopic radial scale lines etched onto the wheel’s rim intercept an optical photo-interrupter sensor. This tracks the micro-step feeding increments of your paper sheets to synchronize perfectly with the moving printhead.
