摘要： The disclosure relates to an operating method for a coating system (e.g. painting installation) for coating components (e.g. motor vehicle body components). Prior to the actual coating operation, the operating method provides for a testing operation comprising the following:



Specification of a test pattern to be applied to a test surface,
Determination of control signals for controlling the coating system, the control signals being determined from the predetermined test pattern and being intended to control the coating system in operation in such a way that the applicator applies the test pattern to the test surface,
controlling the coating system with the control signals so that the coating system applies the test pattern to the test surface with the applicator,
recording an image of the test pattern applied to the test surface by means of a sensor,
determining a deviation between the predetermined test pattern and the recorded image of the actually applied test pattern, and
determining correction values for the control signals depending on the deviation between the predetermined test pattern and the recorded image of the actually applied test pattern.

摘要： An image forming apparatus includes a wireless tag communication device to write data to, and read data from, a wireless tag attached to a sheet. An image forming device in the apparatus is configured to form an image on the sheet. A controller in the apparatus is configured to determine whether a writing of data to a wireless tag was successful based on a notification from the wireless tag communication device and generate investigation support information if the writing was not successful and control the image forming device to form an investigation support image corresponding to the investigation support information if the writing was not successful.

摘要： An image forming apparatus includes an image forming device, a reading device, and circuitry. The image forming device discharges ink droplets through nozzles to form an image on a recording medium conveyed in a first direction. The reading device reads the image formed on the recording medium. The circuitry generates a correction chart that includes patches, located in the first direction and representing different densities from each other, and two marks located at different positions from each other in a second direction perpendicular to the first direction. The circuitry locates opposed end portions of the patches in the second direction outside the two marks in the second direction. The circuitry derives correction data, based on read data of an area of the patches existing inside the two marks in the second direction included in read data provided by the reading device reading the correction chart formed on the recording medium.

摘要： An integrated circuit for a fluid ejection device having actuators to operate during a non-reset operating condition is disclosed. The integrated circuit includes a reset input to receive a reset signal activated for a duration. The reset signal generates a reset condition in the integrated circuit. The integrated circuit also includes a monitor circuit operably coupled to the reset input to indicate if the duration of the reset signal meets or exceeds a selected duration and a nonvolatile memory device having data accessible during the reset condition.

摘要： The disclosure relates to a method and apparatus for preventing oxidation or contamination during a circuit printing operation. The circuit printing operation can be directed to OLED-type printing. In an exemplary embodiment, the printing process is conducted at a load-locked printer housing having one or more of chambers. Each chamber is partitioned from the other chambers by physical gates or fluidic curtains. A controller coordinates transportation of a substrate through the system and purges the system by timely opening appropriate gates. The controller may also control the printing operation by energizing the print-head at a time when the substrate is positioned substantially thereunder.

摘要： A liquid ejection apparatus includes a liquid ejection head having a plurality of nozzles, a determination circuit, a clock, and a controller. The controller is configured to determine whether the clock is in an on or off state. In response to determining that the clock is in an on state, the controller is configured to perform an inspection process at a first time. In the inspection process, the controller drives the liquid ejection head to eject liquid from a nozzle of the plurality nozzles and receive a determination signal that is output from the determination circuit in response to ejection of liquid from the nozzle of the plurality of nozzles. In response to determining that the clock is in an off state, the controller is configured to perform the inspection process at a predetermined time that is a time after the clock is returned to an on state.

摘要： Various methods and systems for a printer having verifiers are disclosed herein. Such methods provide for voiding a printed media in a batch printing run. The methods further correspond to identifying the printed media that is printed as part of the batch printing run as a failed media in an instance an assigned grade fails to satisfy a predetermined threshold, marking the printed media as a failed printed media, determining whether the batch print run is in sequential mode or non-sequential mode, marking the one or more subsequently printed media as additional failed printed media, and reprinting the failed media in sequence after one or more subsequently printed media before continuing the batch printing run if the batch print run is in sequential mode.
