Patent ID: 8600257

Claim:
A printing device comprising: memory configured to store print data; a printing unit configured to print an image corresponding to the print data and a test image based on an operation setting; a sensor configured to measure the test image; and a processor configured to: cause the printing unit to print the test image onto a belt and cause the sensor to measure the printed test image; extract correction requiring data from the print data stored in the memory, the print data representing a first numerical value of a print matter, the correction requiring data representing a second numerical value of the print matter; determine whether a prescribed measurement condition is satisfied; determine whether at least one of two conditions is satisfied upon determining that the prescribed measurement condition is satisfied, one condition being such that a ratio of the second numerical value to the first numerical value is less than a first reference value, another condition being such that the second numerical value is less than a second reference value; and upon determining that the at least one of two conditions is satisfied, bypass measurement by the sensor.
