  • Publication number: 20210294552
    Abstract: A printing system comprises an order receiving system, an information processing apparatus, and one or more production systems. The order receiving system receives print data, generates quality requirement data, and sends the print data and the quality requirement data to the information processing apparatus. The information processing apparatus decides a production system to be used based on the received quality requirement data, and generates a print job having identification information of a quality verification process and submits the print job to the determined production system. The production system executes the quality verification process corresponding to the identification information, and if a condition set by the quality verification process is not met, executes an adjustment process for meeting the condition, and executes the print job when the adjustment process has been completed.

  • Publication number: 20190359450
    Abstract: During a maintenance inspection, an optical rope diameter measuring device is provided at a predetermined position along a path of a wire rope, rope diameter is measured at multiple measuring points while the elevator is driven in test mode, and diameter reduction at each measuring point is determined and stored as a first diameter reduction (S2_S6). During a subsequent maintenance inspection, rope diameter is similarly measured at each measuring point to determine diameter reduction constituting a second diameter reduction (S7_S11). Based on these two diameter reductions, the time at which diameter reduction will reach a predetermined threshold value is predicted for each measuring point, and the earliest time is displayed as a rope replacement time (S12_S14).

  • Patent number: 10289355
    Abstract: An image forming apparatus includes a container in which a sheet is contained, an image forming unit configured to form an image on the sheet, a reading unit configured to read a test image formed on the sheet, and a controller. The image forming apparatus forms the test image on the sheet, reads the test image by the reading unit, and generates, based on a reading result of the reading unit, an image forming condition for correcting a shift between a position of an image to be formed on a first surface of the sheet and a position of an image to be formed on a second surface different from the first surface of the sheet, and determines a timing for the image forming unit to subsequently form the test image based on a time period during which the sheet is contained in the container.
