Printing device that executes calibration at frequency suited to user demand

摘要

A printing device including a printing unit that prints an image with print agent, a calibration unit that executes a calibration process, a specifying unit that specifies a usage amount of the print agent, and a control unit that controls the calibration unit to execute the calibration process at a lower frequency when the specifying unit specifies a lower amount as the usage amount. The calibration process is for printing a mark with the print unit, detecting the mark, and calculating a calculation value based on a detection result.

1. A printing device comprising:
a belt; a belt sensor disposed adjacent to the belt; a specifying unit operated by a user and configured to specify a toner-save mode ON or OFF; a communication unit configured to communicate with an external computer configured to specify the toner-save mode ON or OFF; a printing unit configured to print an image with less amount of print agent while the toner-save mode ON is specified by at least one of the specifying unit and the external computer than while the toner-save mode OFF is specified by at least one of the specifying unit and the external computer; and a control unit configured to execute a density level calibration process at a first frequency when the toner-save mode ON is specified by at least one of the specifying unit and the external computer, and to execute the density level calibration process at a second frequency when the toner-save mode OFF is specified by at least one of the specifying unit and the external computer; wherein the first frequency corresponds to a first amount of time between the density level calibration processes and the second frequency corresponds to a second amount of time between the density level calibration processes, the first amount of time being longer than the second amount of time, and wherein the control unit is further configured to perform the density level calibration process by:
controlling the printing unit to print a calibration image on the belt;controlling the belt sensor to detect the calibration image printed on the belt;generating a calibration data based on a detection result of the belt sensor; andstoring the generated calibration data in the storing unit.
