摘要： An image-forming apparatus includes: a fixing device; a power supply unit; a non-contact temperature sensor; and a control device. The fixing device has a heating member. The power supply unit is configured to supply electric power to the heating member. The non-contact temperature sensor is disposed in a position separate from the heating member and configured to detect temperature of the heating member. A first function and a second function respectively produce a first corrected temperature value and a second corrected temperature value smaller than the first corrected temperature value with respect to a given detected temperature. The control device is configured to: select the first function to correct the detected temperature at a start of a print control process; switch from the first function to the second function at a prescribed timing during the print control process; and control the power supply unit based on the corrected temperature.

摘要： In a wire-dot print head which comprises print elements arranged in a ring, each having an electromagnet formed of a core and a coil, and in which the electromagnets are divided into a plurality of blocks so that each block has a plurality of electromagnets, and a common current conduction control element is provided for each block and used to control current through the coils of the electromagnets in the block, the electromagnets of each of at least some of the blocks are disposed so as not to be physically adjacent to each other. Because of the above arrangement, currents through the coils due to magnetic interference between the adjacent electromagnets is reduced and power consumption is reduced.

摘要： A wire dot printing head includes armatures each of which is coupled to a printing wire, a felt guide for reducing the friction between the printing wires and a printing wire guide, a residual sheet disposed over a magnetic core frame, a biasing leaf spring, and a oil leakage preventing member. Such member is disposed over the armatures to intercept oil flowing from the felt guide. An erroneous dot printing operation due to the arms of the leaf spring sticking to the residual sheet is prevented.

摘要： In an image-forming apparatus, a sheet detector detects the recording sheet conveyed from the sheet accommodating unit by the pickup roller. A fixing unit includes a heating member configured to heat the recording sheet. A power supply unit supplies the heating member with electric power. A control device is configured to: output a signal controlling the pickup roller to convey the recording sheet from the sheet accommodating unit; determine, based on a detection result of the sheet detector, whether the pickup roller succeeds in conveying the recording sheet from the sheet accommodating unit; control the power supply unit to supply the heating member with the electric power such that the electric power per unit time does not exceed an upper limit; and set the upper limit depending on a determination result of whether the pickup roller succeeds in conveying the recording sheet from the sheet accommodating unit.
