    摘要: A dry time sensor apparatus for an ink jet printer includes a light source emitting light onto a selected area of ink on a print medium such that the light reflects off of the selected area of ink. A reflective device receives the reflected light and reflects the light a second time back onto the selected area of ink such that the light is reflected a third time by the selected area of ink in a predetermined direction. The predetermined direction is substantially nonvarying over a range of angles of orientation of the print medium and a range of distances of the print medium from the light source. A reflected light detecting device receives the light reflected in the predetermined direction.

    摘要: Mirror (1) of a laser printhead has an octagonal outer configuration. During normal use the mirror is rotated at high speed, which drives ambient air which causes noise. To control the noise a shroud (11) surrounds the mirror and confines the air except at an opening in the shroud to permit a laser beam to reach the mirror and be reflected out. A rib extends over the mirror and near the area of the opening, positioned to reduce sounds created by the assembly.
