Abstract: Provided is a water-based coating composition capable of forming a multilayer coating film having an excellent finished appearance and having excellent storage stability. A water-based coating composition to be used as a water-based first colored coating (X) in a 3-coat-1-bake multilayer coating formation method which sequentially applies a water-based first colored coating (X), a water-based second colored coating (Y), and a clear coating (Z) and heats and cures the obtained three-layer multilayer coating film simultaneously, wherein the water-based coating composition contains at least one resin selected from acrylic resins (A) and polyester resins (B), a curing agent (C), and urethane resin particles (D) obtained from structural components including a polyisocyanate component (d1) containing at least one diisocyanate (d1-1) selected from xylylene diisocyanate and hydrogenated xylylene diisocyanate and a polyol component (d2).

Abstract: An image forming system includes a plurality of image forming apparatuses and a server. The server is connected to the image forming apparatuses in a communicable manner. The server receives data indicating a numerical value of a common item from each of the image forming apparatuses, calculates a median of the data, and specifies an abnormal image forming apparatus from among the image forming apparatuses that has sent a numeric value of the common item that deviates the most from the median.

Abstract: An image forming apparatus includes a print engine, a sheet transportation unit, an optical sensor, and an image processing unit. The print engine is configured to physically print an image to be printed on a print sheet. The sheet transportation unit is configured to transport the print sheet along a predetermined transportation path. The optical sensor is arranged so as to face the transportation path, and configured to detect a color of a test chart on a colored print sheet transported along the transportation path. The image processing unit is configured to perform color correction of the image to be printed on the colored print sheet, on the basis of the detected color of the test chart on the colored print sheet so as to restrain color change of the image due to a surface color of the colored print sheet.

Abstract: An information processing system includes a first information processing apparatus of a data migration source (first apparatus), a second information processing apparatus of a data migration destination (second apparatus), a server communicable with the first and second apparatuses via a network and a user terminal communicable with the first and second apparatuses by short range wireless communication and communicable with the server via the network. The first apparatus starts export of migrating data by communication with the user terminal and transmits the migrating data having data identification information to the server. The server stores the received migrating data. The second apparatus starts import of the migrating data by communication with the user terminal. The server reads out the migrating data on the basis of the data identification information and transmits the migrating data to the second apparatus. The second apparatus stores the received migrating data.

Abstract: A mobile terminal apparatus receives a setting reference value set of plural setting items for an image forming apparatus from a management server, and transmits it to the image forming apparatus using near field wireless communication. The image forming apparatus determines a setting item of which a current setting value is different from the setting reference value, and transmits through the near field wireless communication to the mobile terminal apparatus adjustment item data that indicates the determined setting item, the setting reference value and the current setting value. The mobile terminal apparatus displays the received adjustment item data, and transmits through the near field wireless communication to the image forming apparatus an adjustment instruction that indicates a setting value of a setting item specified by a user in the adjustment item data. The image forming apparatus changes a setting value in accordance with the received adjustment instruction.

Abstract: A maintenance management device includes: an operation history section and an optimum operation extraction section. The operation history section, upon execution of a plurality of maintenance adjustment operations by a service man, leaves the plurality of maintenance adjustment operations as a history for the purpose of resolving a specific error. The optimum operation extraction section, based on the history, extracts, as an optimum maintenance adjustment operation, a common maintenance adjustment operation executed for the specific error in common by the plurality of service men.

Abstract: The current value comparison unit configured to calculate a first variation amount by subtracting a reference value of a reference chart from a current registered value of a current chart for every setting item based on the reference values for every setting item registered in advance and the current registered values for every setting item. The preceding value comparison unit configured to calculate a second variation amount by subtracting the reference value of the reference chart from a preceding registered value of a preceding chart for every setting item based on the reference values and the preceding registered values for every setting item registered before changing the current registered value. The priority order setting unit configured to display the setting items in descending order of priorities based on the first variation amount and the second variation amount.
