An information processing apparatus includes a processor configured to shift to an energy saving mode in which predetermined functions are inactivated. The processor includes a detection unit that detects a shutdown operation in the energy saving mode of the information processing apparatus, an operation reception unit that displays, when the shutdown operation is detected, a screen in which a user is prompted to determine whether performance of a shutdown process is to be continued, the operation reception unit receiving an operation through the screen, and a shutdown unit that performs the shutdown process when an operation to continue performance of the shutdown process is received through the screen.

A circuit includes a pulse generator to generate an output pulse in response to a signal representing rotation of a fan. A timing relationship between output pulses represents speed of the fan. A filter circuit converts the output pulse to a direct current (DC) voltage signal proportional to the speed of the fan. A monitor circuit monitors the DC voltage signal with respect to a predetermined threshold and generates a control signal that disables a printer dryer if the DC signal does not satisfy the predetermined threshold.

The print object holding tool has a holder that holds a print object at two opposing parts thereof, a horizontal axis rotary mechanism that rotates the print object held by the holder about an axis of rotation horizontally situated; and a vertical axis rotary mechanism that rotates the print object held by the holder about an axis of rotation vertically situated.
