Abstract:
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:
