Abstract: A common electrode driver includes an inverting amplifier including a first resistor, a second resistor, and an operational amplifier, and a resistance ratio adjustment circuit that adjusts, in accordance with a length of one horizontal scan period, a resistance ratio being a ratio of a resistance value of the second resistor to a resistance value of the first resistor. A feedback voltage is provided to one end of the first resistor. The resistance ratio adjustment circuit sets the resistance ratio when second driving is performed, in which a length of one horizontal scan period is a second time longer than a first time, to be smaller than the resistance ratio when first driving is performed, in which a length of one horizontal scan period is the first time.

Abstract: An image forming apparatus includes a controller configured to provide a mobile input function that enables the image forming apparatus to accept input operations from a mobile terminal via a network interface. After starting to provide the mobile input function, the controller sends display data to the mobile terminal via the network interface, thereby causing the mobile terminal to display an operation screen for operating the image forming apparatus from the mobile terminal. The controller displays a standby screen including a particular operable object on a touch panel when the mobile input function is not provided. When the particular operable object is operated, the controller switches the standby screen to a local operation screen. In response to accepting an operation on the local operation screen, the controller performs a process according to what kind of operation has been accepted on the local operation screen.

Abstract: An image forming apparatus includes a network interface, an operation panel including a touch panel, and a controller. The controller is configured to provide a mobile input function to a mobile terminal via the network interface. In response to accepting a first operation to the operation panel with a local operation screen not displayed on the touch panel, the controller causes the touch panel to display the local operation screen, and thereafter switches the local operation screen on the touch panel to a standby screen after waiting until a continuous time with no operation to the touch panel exceeds a first threshold time. In response to accepting a second operation to the operation panel with the local operation screen not displayed on the touch panel, the controller causes the touch panel to display the standby screen without waiting for the first threshold time to elapse.

The controller is configured to: receive a print job through the communication interface and store the print job in the memory; control the touch panel to display a list including one or more job touch keys and a function touch key, the one or more job touch keys being for individually selecting one or more print jobs stored in the memory, the function touch key being for selecting all of the one or more job touch keys included in the list, the list being scrollable along a particular direction; and in response to receiving a scroll operation of the list, controlling the touch panel to cause the list to scroll along the particular direction.

Abstract: An image forming apparatus includes a network interface, an operation panel including a touch panel, and a controller. The controller is configured to provide a mobile input function to a mobile terminal via the network interface. In response to accepting a first operation to the operation panel with a local operation screen not displayed on the touch panel, the controller causes the touch panel to display the local operation screen, and thereafter switches the local operation screen on the touch panel to a standby screen after waiting until a continuous time with no operation to the touch panel exceeds a first threshold time. In response to accepting a second operation to the operation panel with the local operation screen not displayed on the touch panel, the controller causes the touch panel to display the standby screen without waiting for the first threshold time to elapse.

Abstract: An image forming apparatus includes a network interface, an operation panel including a touch panel, and a controller configured to provide a mobile input function to a mobile terminal via the network interface. The mobile input function enables the image forming apparatus to accept input operations from the mobile terminal via the network interface. The controller displays access information on the touch panel when the mobile input function is not provided, and starts providing the mobile input function in response to receiving access from the mobile terminal using the access information via the network interface. After starting to provide the mobile input function, the controller sends display data to the mobile terminal via the network interface, thereby causing the mobile terminal to display an operation screen for operating the image forming apparatus from the mobile terminal.

Abstract: An image forming apparatus, having a mobile input function and a remote input function, includes a network interface, an operation panel including a touch panel, and a controller. After starting to provide one of the input functions, the controller sends display data to an operation terminal via the network interface, thereby causing the operation terminal to display an operation screen for operating the image forming apparatus from the operation terminal. While the mobile input function is being provided, the controller does not display a local operation screen on the touch panel. While the remote input function is being provided, the controller displays the local operation screen on the touch panel, and updates, in response to receiving operation data from the operation terminal via the network interface, display contents on the local operation screen, based on an operation indicated by the received operation data.

Abstract: A printer includes a controller, a memory, and a user interface. The printer has a first mode and a second mode. The controller disables the first mode when enabling the second mode and disables the second mode when enabling the first mode. The controller executes a first printing process while the first mode is enabled. In the first printing process, the controller receives a print job from a client device, stores the received print job in the memory, and performs printing based on the stored print job upon receiving a storage print command. The controller executes a second printing process and restricts the first printing process while the second mode is enabled. In the second printing process, the controller receives a print job from a server in response to receiving a prescribed input operation via the user interface, and performs printing based on the received print job from the server.

Abstract: A printing system includes a printer, a server device, and a client device. The client device receives identification information of a user, and transmits a print job for an image to be printed to the server device. The print job is associated with a computer name. The computer name specifis the client device and is assigned to the received identification information.
