Embodiment Construction

[0027] Exemplary embodiments of the present invention are described with reference to the drawings. The exemplary embodiments are described as examples of the image forming apparatus embodying the spirit of the invention, and are not intended to limit the scope of the invention. The exemplary embodiments are equally applicable to other exemplary embodiments falling within the scope of the invention as defined by the claims.

[0028] first exemplary embodiment

[0029] Refer below figure 1 and figure 2 The image forming apparatus 10 including the load cell torque increase detector 100 of the first exemplary embodiment is described. The image forming apparatus 10 of the first exemplary embodiment includes a load cell torque increase detector 100 . The image forming apparatus 10 detects the period of time it takes for the motor 118 to perform a speed change. The motor 118 serves as a driving unit that drives a load unit 130 including various rollers. Accordingly, the image...

Abstract

Image forming apparatus and image forming method. An image forming apparatus includes at least one load unit, a drive unit that drives the load unit, and a controller that controls the drive unit. The controller determines that at least one of the load unit and the drive unit is malfunctioning if a speed change time period taken for the drive unit to reach a second speed from a first speed deviates from a predetermined threshold.

Description

technical field [0001] The present invention relates to an image forming apparatus and an image forming method. Background technique [0002] Japanese Unexamined Patent Application Publication No. 2004-002202 discloses an invention related to predicting a failure in a drive unit such as a motor in an image forming apparatus. A motor control device configured to control the driving operation of a motor that drives a load unit disclosed in Japanese Unexamined Patent Application Publication No. 2014-002202 includes: a storage unit that stores a value of the drive motor, a measurement unit, and a failure prediction unit. A generation condition of a drive signal, and a standard rise time predetermined as a period from when the motor starts driving in response to a drive signal generated under the generation condition to when it reaches a standard rotational speed, the measurement unit measures the response of the slave motor to the The rising time of the drive signal from the st...
