摘要： A CPU detects a temperature of a central part of a heating roller. If the detected temperature does not exceed 180° C., the CPU drives a central coil or a side-end coil for 0.4 second in accordance with a temperature difference between the central part of the heating roller and a side-end part of the heating roller. Then, the CPU drives the side-end coil or central coil for 0.2 second. Thereafter, the CPU detects the temperature of the central part and repeats the driving control until the detected temperature reaches 180° C.

摘要： An ink-jet recording apparatus comprises a pump, an ink-jet head, and a detector. The pump includes a housing, a rotor, a partition, a first passage, and a second passage. The housing has a cavity formed therein and also has an inlet port through which ink is sucked into the cavity and an outlet port through which ink is discharged out of the cavity. The rotor is rotatable within the cavity. The partition is, together with the rotor, rotatable within the cavity while being supported on the rotor such that both ends thereof can be in contact with an inner surface of the housing. The first passage is formed within the cavity and extends from the inlet port to the outlet port. The second passage is formed within the cavity to be longer than the first passage and extends from the inlet port to the outlet port via a side of the rotor opposite to the first passage. To the ink-jet head, ink is supplied from the pump. The detector detects whether or not the partition is disposed within such a range that a flow resistance in the first passage can be higher than a flow resistance in the second passage.
