    Abstract: A control system is configured such that a carriage that a processing head is mounted is driven by a motor and reciprocates. The motor is controlled by a controller. The controller reciprocates the carriage by selecting a control mode as a target mode based on temperature information related to temperature of the motor and controlling the motor in the target mode. The controller selects the target mode to be applied to the control of the motor for each of particular work units. The target mode is selected from a group of particular control modes. Each control mode in the group of particular control modes is a control mode in which a maximum temperature, which is estimated based on the temperature information, when the control of the motor using the selected control mode would be executed until the processing is completed, is less than a reference value.

    Abstract: The object of this invention is to provide a printing apparatus and printhead temperature retaining control method capable of suppressing power consumption, and reducing degradation in image quality. To achieve the object, a printing apparatus for printing an image on a printing medium by discharging ink, executes the following processes. A first temperature adjustment process is executed to adjust the printhead temperature to a first adjustment temperature during the non-printing period in which preparation for printing the image is executed by discharging ink from the orifices. Additionally, a second temperature adjustment process is executed to adjust the printhead temperature to a second adjustment temperature during a printing period in which the image is printed on the printing medium by discharging ink from the orifices. The process is executed while providing a quiescent period without printhead temperature adjustment between the first and second temperature adjustment processes.

    Abstract: An abnormal current cut off circuit for creating a circuit break when an abnormal current flows in a circuit such as a print head driver circuit for a printer. When a driver section 3 is being driven by a power supply circuit 1, the power supply is provided to a driver circuit 2 which drives the driver section 3 via a transistor 5 which is connected in the power supply line and which is turned on by a transistor 7. When the device goes into a standby state, the transistor 5 is turned off, so that the current is supplied to the carriage motor a and the Line feed motor b within the driver section 3 via the fuse 4 and the diode 6 which are connected in parallel with the transistor 5. If an abnormal current then flows during the standby state, the fuse 4 will be broken, and transistor 7 will be turned off so that transistor 5 will also be turned off which ensures that the power supply line is cut completely.
