A system performs a first analysis operation in which an operation history of an image forming apparatus and input information are analyzed, an issuance operation in which, in a case where a result of an analysis of the first analysis operation satisfies notification conditions, a second analysis operation in which a confidence for the result of the analysis of the first analysis operation is obtained, a transmission operation in which, in a case where the confidence is less than a threshold, a message requesting further input of input information is transmitted, and a control operation in which the notification conditions are controlled based on the input information obtained as a response to the message.

Method of analyzing state of image forming apparatus based on running sound

An information processing apparatus includes: one or more processors; and one or more memories storing one or more computer programs. The one or more computer programs, when executed by the one or more processors, cause the information processing apparatus to function as: a reception unit configured to receive history information, from a device, indicating an operation history of a predetermined operation in the device; an analysis unit configured to analyze a condition of the device based on the history information in a case where an execution condition is satisfied; and a setting unit configured to set the execution condition, and wherein the setting unit sets the execution condition based on an analysis result by the analysis unit.

Information processing apparatus for analyzing condition of device

There is provided an image forming system including at least a first image forming apparatus that includes a first image forming unit and an obtaining unit configured to obtain operation-related information related to an operation of the first image forming unit. The image forming system further includes a carryover unit configured to carry over, to a second image forming apparatus, information related to an operation of a second image forming unit of the second image forming apparatus among the operation-related information obtained by the first image forming apparatus when the second image forming apparatus is newly used in the image forming system. The operation-related information includes operation history information of the first image forming unit.

Image forming system, information carryover method, server apparatus, storage medium, image forming apparatus, and image processing system

An image forming apparatus comprises an accommodating unit that accommodates recording materials and has a regulating plate that regulates a trailing edge of the recording material in a feeding direction, detects a recording material fed from the accommodating unit, and measures time from a predetermined timing until a recording material is detected. An information processing apparatus receives time data obtained by a measuring unit from the image forming apparatus, classifies a plurality of time data received from a reception unit into a first group and a second group in accordance with a length of time, and determines using time data included in the first group and the time data included in the second group whether a position of the regulating plate is misaligned in relation to a reference position that corresponds to a size of the recording material accommodated on the accommodating unit.

Image forming system and image forming apparatus

When an excess period, which is period in which the total of the power predicted by a power predicting unit and power stored by a power storing unit exceeds a predetermined power, exists during continuous feeding, the power supply to a plurality of heating elements by an power control unit is adjusted so that the total of the power supplied to the plurality of heating elements and power stored by the power storing unit does not exceed the predetermined power at least during the excess period, and, after the excess period, the transport interval is adjusted so that the temperature rising to a target temperature of the plurality of heating regions by supplying power in which the adjustment is cancelled is completed before the arrival of the recording material to the fixing portion.

Image forming apparatus

An image forming apparatus includes first and second conveyance and calculation units, a reverse unit, a control unit, an image forming unit, and a stack unit to stack sheets. A recording material is conveyed from the stack unit to the image forming unit. The recording material is conveyed reversely, and is conveyed to a double-sided conveyance path and to the image forming unit. Without causing a recording material to wait in the reverse unit, a first recording material is conveyed from the stack unit, then a second recording material is conveyed, and subsequently a third recording material is conveyed. A conveyance interval time and a maximum waiting time are calculated. When the conveyance interval time exceeds the maximum waiting time, the second recording material conveyance starts at timing based on a waiting time after conveyance of the first recording material, and the third recording material conveyance starts at a timing.
