Abstract: An image forming apparatus includes: an image forming unit that performs image forming processing on a recording sheet; a primary central processing unit (CPU) and a secondary CPU, where the primary CPU receives a job externally and instructs the secondary CPU to monitor and control the image forming unit to perform the image forming processing; sensors that sense a state of the image forming unit and output sensor data indicating the state of the image forming unit, a first transceiver; and a second transceiver. The secondary CPU monitors the sensor data to generate diagnostic data. The first transceiver performs duplex communication with the primary CPU to send and receive data other than the diagnostic data. The second transceiver sends the diagnostic data to the diagnostic server without relaying via the primary CPU.

Abstract: An image forming device including an image former, a primary controller, a secondary controller, one or more sensors, an interface, and a writer. The image former executes image forming processing to form an image on a sheet. The primary controller instructs the secondary controller to control the image former to execute the image forming processing. Each sensor detects a state of the image former and outputs sensor data to the secondary controller. The interface can be connected to a storage medium. The secondary controller generates diagnostic data based on the sensor data. The writer writes the diagnostic data to the storage medium via the interface. The diagnostic data is used by a diagnostic server to perform failure diagnostics and life prediction pertaining to the image forming device, after transfer to the diagnostic server via a transfer device when the storage medium is mounted to the transfer device.

Abstract: A sheet feeder includes: a tray in which sheets are stored; a feeding part that feeds the sheets in the tray; and a hardware processor that: measures a conveyance speed of the sheets fed by the feeding part; compares the measured conveyance speed with a first standard speed and detects wear in the feeding part; detects an interval between a previous sheet and a following sheet when the following sheet is continuously fed after the previous sheet; and carries out a control to change the conveyance speed of the sheet from a predetermined speed based on the detected interval to correct the interval between the previous sheet and the following sheet. The hardware processor detects the wear in the feeding part based on the conveyance speed measured while the control to change the conveyance speed is not carried out.

Abstract: An image forming device includes: an image former that executes image forming processing to form an image on a sheet; a primary controller; a secondary controller that controls the image former; a sensor that detects a state of the image former and transmits sensor data indicating the state to the secondary controller; a first transmission path between the secondary controller and the primary controller; and a second transmission path different from the first transmission path. The primary controller instructs the secondary controller to execute the image forming processing. Data related to the execution of the image forming processing is transmitted through the first transmission path. The secondary controller generates diagnostic data for failure diagnostics from the sensor data and life prediction relating to the image forming device and transmits the diagnostic data to the primary controller via the second transmission path.

Abstract: An image forming apparatus performs a serviceman call detection mode during its idling time. In this time, a control portion controls upper and lower pressuring rollers to be clamped, controls a driving motor, and controls a change-over mechanism to switch a braking motor off. A torque detection portion detects a torque value Y of the driving motor at this time. The control portion then controls the upper and lower pressuring rollers to be clamped, controls the driving motor, and controls the change-over mechanism to switch the braking motor on. The torque detection portion detects a torque value Z of the driving motor at this time. The control portion subtracts the torque value Y from the torque value Z to calculate a difference value. The control portion determines that the breaking motor is broken down when the difference value does not exceed the threshold value.
