An information processing apparatus includes a processor configured to: control an operation of the information processing apparatus by executing a control program; in response to reception of an instruction to enter a power-supply off state, determine whether a first power-supply off state is allowed to be entered, the first power-supply off state being a state in which, while a current operation state is held without execution of a restart of the control program, the operation is stopped; in response to a determination result indicating that the first power-supply off state fails to be entered, perform a redetermination after a lapse of a set time, the redetermination determining whether the first power-supply off state is allowed to be entered; and in response to the redetermination determining that the first power-supply off state is allowed to be entered, cause the first power-supply off state to be entered, and, in response to the redetermination determining that the first power-supply off state is not allowed to be entered, cause a second power-supply off state to be entered, the second power-supply off state being a state in which, after the control program is restarted and an initialization process is performed, the operation is stopped.

Provided is an image processing apparatus that can efficiently utilize the storage capacity in image processing. A dividing unit divides inputted image data into a plurality of partial data. An analysis unit analyzes whether or not each of the plurality of partial data divided by the division unit is suitable for compression at any of a plurality of stages of image processing in which feature of image changes. A compression unit compresses the partial data at the stage when the analysis unit analyzes that it is suitable for compression. A decompressing unit decompresses the partial data compressed by the compression unit at the stage when it is compressed. A processing execution unit executes processing at the stage of image processing on the partial data decompressed by the decompressing unit.

A non-transitory storage medium stores a plurality of instructions readable by a computer of an information processing apparatus. The information processing apparatus comprises a communication interface for connecting to a scanner. The information processing apparatus includes a first route and a second route. When executed by the computer, the plurality of instructions cause the information processing apparatus to execute a scan control using the first route in which a read result of a document by the scanner is obtained by using the first route after receiving an execution instruction for scanning, determine whether the scan control using the first route has failed or not, and execute a scan control using the second route in which the read result of the document by the scanner is obtained by using the second route when it is determined that the scan control using the first route has failed.

A communication apparatus includes a control unit configured to perform, in a case where the communication apparatus is operating in a connection setting mode and a predetermined process is completed, control to stop operation in the connection setting mode based on passage of a second time longer than a first time without performance of connection setting from a start of an operation of the communication apparatus in the connection setting mode.

According to an embodiment, an image processing apparatus includes a communicator, a storage, and a controller, in which the controller stores destination information received from a terminal device, via the communicator, in the storage, and erases the destination information from the storage in response to a trigger. In the image processing apparatus, the destination information is retained at least until a trigger input is made.

An image processing apparatus transmits a request to a content server at a specific timing such as login, logout, auto-clear, print start. The image processing apparatus receives contents provided from the content server in response to the request, and displays the contents in an operation unit. If a user operating the image processing apparatus is specified by user authentication, the image processing apparatus adds information of the user to the request, and receives the content modified by the content server according to the information of the user from the content server and displays the modified contents.

An image signal processing device includes a reference signal generating portion, a determination portion, and an extraction portion. The reference signal generating portion generates and outputs a reference signal that sequentially transmits reference pulses shifted from horizontal synchronization pulses on a horizontal synchronization signal by a predetermined shift time. The determination portion determines whether the horizontal synchronization pulses are normal by comparing time differences between input of the horizontal synchronization pulses and input of the reference pulses with the shift time. The extraction portion extracts line image data points from an image signal in synchronization with the input of the horizontal synchronization pulses that have been determined as normal.

A supporting program according to aspects of the present disclosures can be executed by a CPU of a PC and corresponds to a printer connected to the PC. When the PC receives a print instruction to cause the printer to perform printing through a general-use printing program implemented in the OS of the PC, in advance, the supporting program causes the PC to output a preceding operation command to cause the printer to perform a preceding operation before starting printing. The printer performs a preceding operation corresponding to the preceding operation command

A drive transmission device includes a chassis fixed to an apparatus main body and a driving roller that is driven by a driving source. A belt member transmits rotational force of the driving roller. A tension roller contacts the belt member to apply tension to the belt member. A support member supports the tension roller rotatably and is swingable about a rotational shaft of the chassis. A screw fixes the support member to the chassis at a predetermined position. A retaining member is able to be engaged with the chassis, in which the support member is arranged and fixed between a part of the retaining member and the chassis in an insertion direction of the screw.
