摘要： A method is disclosed for the calibration of a multichannel printer. The printer comprises a plurality of diode lasers which are modulated in accordance with an information signal. Radiation from the diode lasers is imaged onto a receiving medium such as a thermal print medium. The thermal print medium is supported on a drum which is rotatable about an axis. In order to balance the output from the diode lasers, test patterns are formed on the receiving medium with each of the lasers using known power inputs. The density of each of the test patterns is measured, and the density values obtained are correlated with the input power levels for each of the lasers. The measurement of densities produced by a single laser is facilitated by slowing the print head down by a factor of the number of lines normally printed and writing with one line source at a time.

摘要： A thermal printer is capable of printing proofs of images on a receiver with any of a plurality of selected half-tone dot patterns. The proof image is generated with a series of incremental dots. A plurality of the incremental dots are generated substantially simultaneously as a swath. The image is formed as a composite of a plurality of the swaths. The printer has the capability of printing with various swath widths. The swath width for a particular image is selected to preclude visible beating of the incremental dots against the selected half-tone dot pattern. Any image artifacts which are a product of interaction of the selected half-tone dot pattern and image elements (such as picket fences) are properly illustrated on the proof image. Image artifacts that are the product of interactions of the incremental dots and the half-tone dots are made invisible to the human eye.

摘要： An image processing apparatus (10) comprises an imaging drum (300) for holding print media (32) and donor material (36) in registration on the imaging drum (300). A print head (500), driven by a lead screw (250) and stepper motor, moves along a line parallel to a longitudinal axis (X) of the imaging drum (300) as the imaging drum (300) rotates. The print head (500) is brought repeatably to a mechanical registration position using sensors. For coarse positioning, the print head (500) is moved to a first linear sensor position, with the drive motor operated in full-step mode. For fine positioning, the drive motor is then operated in microstepping mode, during which a second sensor detects rotational orientation by detecting a rotational indicator mounted on the lead screw (250). The rotational indicator permits straightforward adjustment for fine-tuning, being adjustable to any one of a number of fixed positions relative to lead screw rotation.

摘要： A laser diode controller (30) having a constant current source (60) which supplies current to a laser diode (90) is disclosed. A current shunt switch (40) directs current to either the laser diode (90) or to a bypass circuit (42). A thermal compensator (70) alters a current level of the constant current source (60) as a function of on-time of the laser diode (90) to compensate for changes in optical power conversion efficiency due to temperature changes in the laser diode. A thermo electric cooler controller (80) maintains a constant temperature of a substrate on which the laser diode is mounted. In one embodiment, an array of sample and hold amplifiers (50) eliminates a need for multiple DACs.

摘要： A multiple-source array for use in thermal printing uses source interleaving to avoid overlapping of the dye-transfer tracks upon the donor material in a single pass. This prevents the formation of artifacts in the image because of thermal interaction among either the sources or printing spots. This also permits the thermal array to be oriented predominantly perpendicular to the first-scan direction so that any arcuate shape of the array causes minimal spacing variations of the scan lines and minimizes spacing variations in focus for laser-thermal printing or document source separation for resistive-head thermal printing. Interleaving also allows multiple printheads to be used even when they have different printing characteristics. The array includes independently addressable printing element data channels and a data distributor allowing interleaving to be accomplished in the printhead. The printhead also includes pixel replication circuitry that allows pixel replication in both the fast and slow scan directions.
