  • Patent number: 10638003
    Abstract: A printing apparatus performs printing using a plurality of sheets different in size. Stored instructions are executed to act as a display control unit displaying an operation guidance on a display unit for setting a sheet in a sheet tray, and a data acquiring unit acquiring regional information of the printing apparatus. When the data acquiring unit acquires regional information indicating a first region, the display control unit displays an operation guidance including content that notifies a user of a specific operation that is to be performed on the sheet tray so that it is able to hold a sheet having a first sheet size. When the data acquiring unit acquires regional information indicating a second region which is different from the first region, the display control unit displays an operation guidance not including the content that notifies a user of the specific operation.

  • Patent number: 10212301
    Abstract: A PC registers in advance PC-assistant copying functions which can be provided by the printer driver for a MFP. The MFP presents, to the user, copying functions including the registered functions. Upon reception of a copy instruction, the MFP determines whether selected functions include a PC-assisted copying function. If the selected functions include a PC-assisted copying function, the MFP transmits, to the PC, scanned image data and a job ticket containing information representing the selected functions. Upon reception of the job ticket, the PC generates a print job for printing the image data on the basis of the job ticket, and transmits the print job to the MFP.

  • Patent number: 9879762
    Abstract: A jump shift of an automatic transmission with multiple shift speeds such as, e.g., ten forward speeds involves operation of many engagement elements. The shifting operation for the jump shift is therefore complicated, making it difficult for the automatic transmission to respond quickly. After shifting to the seventh speed as a direct coupling speed is completed by engaging three clutches C1, C3, C4, the remaining other clutch C2 is also engaged at the seventh speed. In the case of a jump shift, e.g., a shift from the seventh speed to the fifth speed, shifting to the fifth speed is completed by disengaging the clutch C1 and performing control to disengage the clutch C3 and to engage a brake B1 with the remaining other clutch C2 kept in the engaged state. This facilitates the shifting operation from the direct coupling speed and allows the automatic transmission to respond quickly.
