摘要:
Gutverarbeitungsgerät, mit einer Tintendruckvorrichtung zur Erzeugung von Abdrucken, mit einem Transportmodul, an welches ein auf der Seite liegender Druckträger mittels einer Andruckvorrichtung angedrückt wird, wobei der Druckträger während des Druckens in eine Transportrichtung x transportiert wird. Ein Druckmodul (10) weist einen einzigen Tintenstrahldruckkopf oder eine einzige Tintenkartusche (12) mit einem Tintenstrahldruckkopf auf, der einen mindestens 1 Zoll breiten Abdruck ermöglicht. Der Tintenstrahldruckkopf kann quer zur Transportrichtung x sowie in eine dazu orthogonale vertikale z-Richtung des kartesischen Koordinatensystems und entgegengesetzt dazu verschoben werden, solange das Drucken unterbrochen wird. Eine Bewegungsmechanik (25) zum vertikalen Anheben und Absenken des Tintenstrahldruckkopfes vorgesehen ist. Die Bewegungsmechanik (25) umfasst einerseits Mittel (252) zum motorischen Verstellen des Tintenstrahldruckkopfes sowie andererseits Mittel (254) zur Handverstellung in der vertikalen z-Richtung, wobei die Mittel (254) zur Handverstellung vorgesehen sind, um den Tintenstrahldruckkopf durch vertikales Verstellen in eine vorbestimme Position zu bringen.

摘要:
A printing apparatus includes a transport mechanism section which has a support surface that supports and transports a workpiece, a printing mechanism section which has an ink jet head that executes printing on the workpiece that is transported by the transport mechanism section, a detecting section which is provided further on the upstream side in the transport direction than the ink jet head and detects an upper surface position of the workpiece, an adjustment section which adjusts a separation distance between the support surface and the ink jet head, and a control section. In addition, the control section selects a first mode for printing and a second mode for stopping printing by adjusting the separation distance by operating the adjustment section based on a detection result of the detecting section.

A method and system are disclosed for ejecting ink drops from a plurality of ink jet nozzles in order to print on an envelope in a mail piece production process. The envelope has been stuffed and is therefore not flat, especially near the edges. Mail piece composition data is obtained and stored for the mail piece, and based upon that composition data a nozzle delay pattern is determined. For each ink jet nozzle, ink is ejected in accordance with the delay pattern so as to contact a point of the envelope's surface at the same time as drops from other ink jet nozzles.

Printhead-to-platen spacing (PPS) variation (53) along a scan axis (17) is found by shining a light beam from pen carriage (12) to print-medium position (15) and back to detector (21,21'), and applying a pathlength/intensity correlation (44). Sensing is done while scanning, to find relative PPS profile (53) along the track. With no medium in place (Fig.4) this measures mechanical imperfections ― and can be corrected by later deducting thickness (t) of a medium (16). If medium is present (Fig.5), adjustment is omitted. For absolute values a plural-lamp (20',20") sensor is calibrated for each lamp, at the PPS design point (Fig.7). Pagewide/webwide variants are included.
摘要:
An inkjet printer is provided, which is configured to acquire gap information related to a gap between an ink discharging surface and a recording sheet in each individual position of top-formed positions and bottom-formed positions within a predetermined wave-shape generating range, identify, when the predetermined wave-shape generating range includes a partial range in which the recording sheet is not placed, a top-formed position where the gap information has not been acquired and a bottom-formed position where the gap information has not been acquired, within the partial range, complement the unacquired gap information in the identified top-formed position with a value determined based on the respective pieces of gap information acquired in other top-formed positions, and complement the unacquired gap information in the identified bottom-formed position with a value determined based on the respective pieces of gap information acquired in other bottom-formed positions.
摘要:
[Object] To provide a method and apparatus for discharging a liquid material, which can solve the problems regarding the occurrence of a satellite and accuracy of a landing position. [Solving Means] In a method for discharging a liquid material in the state of a liquid droplet through a discharge orifice by applying inertial force to the liquid material, the method is characterized in comprising the steps of measuring a distance A from a lower end of the discharge orifice to a lower end of the liquid material having flowed out from the discharge orifice at the time when the liquid material having flowed out from the discharge orifice separates from the discharge orifice, and setting a distance B between the lower end of the discharge orifice and a work surface to be approximately the same as the distance A. An apparatus for carrying out the method is also provided.
