Image forming system, determination method, computer program, and recording medium

To provide a technique capable of predicting a time when an image forming system fails.SOLUTION: In the image forming system, the controller is configured to input, to the motor driver, an operation amount for moving the carriage in the main scanning direction at a target speed based on the moving speed of the carriage detected from the encoder signal. The motor driver is configured to drive the motor by applying driving power based on the operation amount to the motor. The rotational movement of the motor is converted into a translational movement of the carriage. On the other hand, in order to determine the lifetime or the remaining lifetime of the image forming system, for each of a plurality of periods, time-series data of the moving speed, the physical quantity related to the moving speed, or the operation amount observed by the movement control of the carriage in the corresponding period is acquired. An index value related to an abnormality of the image forming system is identified based on the time-series data. The life or the remaining life of the image forming system is determined based on the transition of the index value in the plurality of periods.SELECTED DRAWING: Figure 5

The CPU outputs an ON signal or an OFF signal to the electronic governor circuit. A CPU outputs an ON signal to an electronic governing circuit to rotate a carrying motor at a first speed V1 when carrying media. When stopping the conveyance of the media, the CPU executes deceleration processing for alternately switching output of an ON signal and output of an OFF signal so that the conveyance motor rotates at the second speed V2. After continuing the deceleration processing for a predetermined period, the CPU outputs an OFF signal to the electronic governor circuit.SELECTED DRAWING: Figure 8
