Abstract:
1. A paper wrinkle sign monitoring device comprising: an information acquiring unit that acquires printing conditions of printing media; at least one timing detecting unit that is set on a transport path of the printing media, and that detects transporting times which are an amount of time it takes for the respective print media to be transported a specified distance; and a sign output unit that determines a sign of paper wrinkle generation in the transporting times of the printing media and outputs a notification of the sign, wherein: the determination of the sign of paper wrinkle generation is based on at least one of an average and a standard deviation of the transporting times of the printing media detected by the at least one timing detecting unit, the at least one of the average and the standard deviation is calculated only from the transporting times of printing media which have a printing condition that coincides with a predetermined recording condition, the at least one of the average and the standard deviation is determined based upon a first predetermined number of detected transporting times, and the detected transporting times are stored in a storage unit that overwrites an oldest stored detected transporting time when a number of stored detected transporting times exceeds the first predetermined number of detected transporting times.
