The Disk Encoder (Encoder Wheel) is a premium-quality compatible replacement designed for Epson EcoTank L3110, L3115, L3116, L3150, L3156, L3250, and L5190 ink tank printers. This encoder disk is mounted on the paper feed motor shaft and works with the encoder sensor to monitor motor rotation and paper feed movement with high precision.
During every print job, the printer reads the transparent encoder markings on the disk to determine the exact rotation of the paper feed mechanism. If the encoder disk becomes cracked, scratched, dirty, bent, or damaged, the printer may lose position feedback, resulting in paper feed errors, print alignment problems, carriage synchronization issues, or abnormal printer operation.
Replacing the faulty encoder disk restores accurate motor feedback, smooth paper feeding, and consistent print quality without replacing the complete paper feed assembly.
Manufactured using precision optical-grade transparent material, this encoder disk provides accurate signal detection, excellent durability, and long service life. It is an ideal spare part for printer technicians, service centers, and professional printer maintenance.

Why Replace the Disk Encoder?
The Disk Encoder provides precise rotational feedback from the paper feed motor to the printer’s main board. Over time, dust, ink splashes, scratches, cracks, bending, or physical damage can prevent the encoder sensor from reading the disk correctly.
Replacing the damaged encoder disk restores accurate paper feed timing, proper print alignment, and smooth printer operation while avoiding replacement of the complete motor assembly.
