Abstract: An apparatus for directing media sheets from a media tray to a feed roller may be coupled to a feeder module. The apparatus includes a support member, a coupler, and a media director. The support member extends across a portion of a media tray width. The coupler extends from the support member and is configured to engage a feeder module to install the support member in a printer. The media director extends from the support member, and is configured to direct a leading edge of a media sheet moving from the media tray towards a feeder nip in the feeder module. The media director is vertically displaced from the support member and the coupler.

Abstract: This invention provides a reader device (10) for a test strip (14) (in particular an immunoassay test strip). The reader device has a channel (12) for receiving the test strip, and a movable sensor (26, 28, 30) located adjacent to said channel. The sensor comprises a source of radiation (26) and a detector (28, 30) for detecting the intensity of emitted radiation. The reader device also has a calibrating attenuator (50) allowing variations in the intensity of radiation emitted by the source to be detected and thereby eliminated or compensated. The invention also provides a method of using the reader device.

Abstract: A vacuum transport for a printer or copier guides a sheet through a machine, such as from a photoreceptor toward a fuser. The vacuum transport includes a partially enclosed vacuum chamber having rollers rotatably mounted therein. Portions of the rollers protrude through openings in the top of the chamber. A series of ribs are disposed between the openings. Some of the ribs extend diagonally toward one end of the width of the paper path over the transport.
