摘要： When a first server node fails in a cluster system, a client node device transmits failure detection information to a second server node device. Upon receipt of the failure detection information, the second server node device transmits a survival confirmation request to the first server node device. When receiving no survival confirmation response from the first server node device, the second server node device determines that the first server node device has failed and starts the switching control of a server node device which performs a service process. Upon receipt of failure detection information, the second server node device starts switching control when further receiving failure detection information from another client node device.

摘要： An image testing method which improves an image testing ability and enables rapid testing processing. When an operator effects testing for an image displayed at a set test position and instructs alteration of a printing condition set by the testing, the image is scrolled and the next image is displayed at the test position without the altered image being displayed. When the next image is displayed at the test position, the operator starts testing for the next image without moving his/her line of vision.

摘要： A control device (10) includes an acquirer (32), a timing detector (33), a controller (30), and a driver (31). The acquirer (32) is configured to acquire an output voltage from a light detector (16) for receiving laser light scanned by a light source (12) and a deflector (13). The timing detector (33) is configured to detect reference timings of the laser light on forward and backward paths in a scanning direction based on the output voltage. The controller (30) is configured to generate a control signal for causing the light source (12) and the deflector (13) to draw a forward path image on a scanned surface from time obtained by adding a time to the reference timing on the forward path and to draw a backward path image on the surface from time obtained by adding a time to the reference timing on the backward path. The driver (31) is configured to draw the images by driving the deflector (13), based on the control signal.
