    摘要： In one embodiment, a drop detection method includes: moving a light source along a first side of the drop zone to illuminate drops passing through a drop zone; and, without blocking any part of the drop zone, detecting light scattered off the drops as the drops pass through the drop zone. In another embodiment, a drop detector includes: a light source on a first side of the drop zone for illuminating drops passing through a drop zone; a light detector on the first side of the drop zone near the light source and a movable carriage carrying the light source and the light detector. The light detector is exposed to the drop zone for detecting light scattered off drops as the drops pass through the drop zone. The carriage is movable along the first side of the drop zone in a direction transverse to the drop direction.

    摘要： A system of classifying incoming media entering an inkjet printing mechanism identifies transparency media without requiring any special manufacturer markings. The media is first optically scanned using a blue-violet light at an initial intensity to obtain both diffuse and specular reflectance data. If useable, the data is compared with known values to classify the media so an optimum print mode tailored for the particular media is used. The early transparency detection system avoids time-consuming further steps trying to classify the media as photo media, plain paper, and the like, and facilitates fast printing of transparencies, which can be critical in the business environment when making last minute changes for a presentation. A printing mechanism constructed to implement this method is also provided.

    摘要： A system of classifying the type of incoming media entering an inkjet or other printing mechanism is provided to identify the media according to markings or identifying indicia on the back surface of the media opposite the printing surface which ultimately bears the printed image. The printing surface of the incoming media is optically scanned using a blue-violet light to obtain both diffuse and specular reflectance values. A spatial frequency signature for the incoming media is compared with known values for different types of media to classify the media according to major categories (transparencies, glossy photo media, premium or plain paper), and specific types of media within these categories (matte photo, premium, or high-gloss photo media). An optimum print mode is selected according to the determined media type to automatically generate outstanding images without bothersome user intervention. A printing mechanism constructed to implement this method is also provided.

    摘要： A system of classifying incoming media entering an inkjet printing mechanism identifies the media without requiring any special manufacturer markings. The media is first optically scanned using a blue-violet light at an initial intensity to obtain both diffuse and specular reflectance data. If useable, the data is compared with known values for different types of media to classify the media so an optimum printmode tailored for the particular media type is used. If the initial data is unusable, successive scanning passes are preformed to find useable diffuse data, and if found, then to find useable specular data. During these successive passes, following an initial calibration scan for the media, each successive scan reduces the scanner intensity until reaching a minimum intensity. If upon reaching the minimum intensity, no useable data has been found, then a default printmode is selected. A printing mechanism constructed to implement this method is also provided.

    摘要： In an inkjet printing machine, an ink drop error correction apparatus includes a position extrapolator that is responsive to conventional position encoder pulses and uses a second order polynomial equation to compensated for ink drop distortions induced at higher carriage velocities of at least 25 inches per second for generating a series of nozzle firing sub-pulses that account for different carriage velocities. A fire pulse generator responsive to the sub-pulses further adjusts the firing time of the printing machine nozzles to correct for the carriage velocity induced ink drop positional errors for both non constant and constant carriage velocity conditions.
