Abstract: A carriage-mounted optical sensor for an ink-jet hard copy apparatus includes a unitary light tube member which holds the optical components in fixed positions relative to each other as well as relative to an outer protective casing which attaches to the carriage. The light tube member serves as a cap to capture two LEDs between itself and a protective casing, to capture an optical lens between itself and a photocell holder, and to directly engage the casing. An inner wall having light redirecting features provides an improved light path cylinder and the device obtains a more accurate representation of the test pattern mark shape, reflectance value, and position.
