摘要： A printing apparatus includes an image reader for reading an image on a printed paper sheet to obtain image data, and a controller for controlling the image reader to obtain image data about a color chart including solid patches once for every predetermined number of printed sheets or at every predetermined time interval which is inputted and set. The controller processes the image data to compute a printed density of each solid patch. Measurement data including the printed density are sequentially stored in a storage section in association with the number of printed sheets or time. The measurement data stored in the storage section may be displayed by a display section or outputted to a print section in the form of history data indicating measurement data transitions. Thus, the printing apparatus including a device for measuring printed sheets can perform history management on the measurement data for every predetermined number of printed sheets or at every predetermined time interval.

摘要： A controller in the example of this invention operates to perform flushing by ejecting three types in size of ink droplets, i.e., smaller, middle and larger ink droplets, from each of nozzles. Then the controller operates an ink-droplet detector to perform an ejection test to detect ejection conditions. Thereafter, the controller operates an ink supply section to perform cleaning in accordance with results of the test. A combination in size of unejected ink droplets indicates a defective condition of the nozzle. Consequently, varying the degree of cleaning the nozzles in accordance with the size of the unejected ink droplets may achieve cleaning in a shorter time of period. As a result, time for cleaning the nozzle can be suppressed. This leads to a decreased proportion of maintenance to a starting time in an apparatus and increased availability of the apparatus.

摘要： After an ink feeding rate or a dampening water feeding rate is varied, a variation in the ink feeding rate or dampening water feeding rate is prohibited for a waiting period. The waiting period for prohibiting a variation in the ink feeding rate is determined by a pattern area rate of a corresponding region. The waiting period for prohibiting a variation in the dampening water feeding rate is determined by an average pattern area rate of all regions or a minimum pattern area rate among pattern area rates of all regions. When one of the ink feeding rate and dampening water feeding rate is varied, a variation in the other feeding rate is prohibited for a set period of time.
