I recently found a really old printer and took it apart. inside is a plastic encoder disk, so I googled the part number to see how many lines where in the encoder and all I found where links to buy it for 50-80 US Dollars. Are those websites scams or can I sell it for that much?
the part number for encoder disk is: C4557-80019
picture below, Diameter of the encoder disk is 1.9 inches
