摘要： An image forming apparatus includes a first counter in which a number of light emitting occurrence for each of a plurality of light emitting elements configured to emit light onto an image carrier, is stored, and a processor configured to obtain a difference in the number of light emitting occurrences between a light emitting element having a larger number of light emitting occurrences and a light emitting element having a smaller number of light emitting occurrences, and to cause at least one of the light emitting elements to emit light, based on the difference.

摘要： An image forming device according to an embodiment includes a photosensitive drum and a light-emitting unit with a plurality of light-emitting elements which form an electrostatic latent image on the photosensitive drum. A processor controls a storage unit to store a cumulative light emission time of each light-emitting element. The processor further controls the storage unit to store an adjustment time which is shorter than a longest cumulative light emission time of the light-emitting elements. When a predetermined condition is satisfied, the processor controls at least one of the light-emitting elements that has a cumulative light emission time which is shorter than the adjustment time to emit light until the cumulative light emission time thereof equals the adjustment time.

摘要： An image data transfer control device includes a first interface, a first and a second memory, a processor, and a second interface. The first interface acquires image data transferred in predetermined units. The first memory stores inclination correction data corresponding to the inclination of a print head, and correction position data indicating a correction position included in at least one divided image line among the predetermined number of divided image lines including each divided image line group. The second memory stores correction target image data at the correction position. The processor selects each divided image line group based on the inclination correction data, and specifies first and second correction target image data. The second interface outputs the second divided image line group including the first correction target image data instead of the second correction target image data.

摘要： According to at least one embodiment, a failure prediction server includes an interface, a memory, and a processor. The interface is configured to communicate with equipment including a component that deteriorates over time. The memory is configured to store measurement data acquired from the equipment. The processor is configured to set a monitoring start condition for failure prediction in the corresponding equipment based on the measurement data acquired as initial data from the equipment, accumulate the measurement data acquired from the equipment in the memory after the monitoring start condition is satisfied, and predict a failure of the component based on the measurement data accumulated in the memory.
