GLASS SETTINGS : • LEFT SIDE GLASS : adjusts which CCD pixels are used on the CCD array in the flatbed optical unit when scanning from the flatbed. • LEADING EDGE GLASS :
adjusts the time between when the flatbed optical unit carriage leaves the “home” position and when the CCD on the flatbed optical unit starts to read that the flatbed optical unit is moving. • GLASS SCALING : adjusts the flatbed optical unit carriage speed. C8523-90921 Service-level diagnostics 207
