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

Method for controlling a digital inkjet printer
A method for printing a digital image in swaths with a swath time corresponding to the width w1 of the digital image on the image receiving medium 2 in the main scanning direction X. The print controller 10 issues a trigger that a spitting action for at least part of the printing elements 8 of the print head 4a, 4b, 4c, 4d, 4e needs to be performed. A swath time of subsequent swaths is gradually increased until the print head reaches a maintenance tray 11 at a side of the print surface 1. The print head stays at the maintenance tray 11 until air between the print head and the maintenance tray 11 has approximately reached a standstill. Then the at least part of the printing elements 8 of the print head are spitting marking material in the maintenance tray 11. After the spitting the swath time of subsequent swaths is gradually decreased until the swath time is corresponding again with the width w1 of the digital image on the image receiving medium 2 in the main scanning direction X. The invention further relates to a digital inkjet printer configured to perform the above mentioned method.
