摘要： In a wire-dot impact printer having a capacitance detector for detecting a displacement of each armature by a sensor electrode arranged opposite the armature, a space is formed between each sensor electrode and its associated armature, and a shield pattern is formed with a small space left around each sensor electrode. The shield pattern is fed with a potential at least equal to the potential of each sensor electrode. This makes it possible to reduce the influence of noise upon detection of a capacitance by the capacitance detector. A noise canceling electrode is also disposed around each sensor electrode and is connected to the sensor electrode, whereby a noise canceling circuit is further provided to eliminate noise voltage. The noise canceling circuit can eliminate a noise voltage picked up by the sensor electrode and the noise canceling electrode.

摘要： A drive system for a wire dot head is provided with sensors for detecting displacements of corresponding print wires. Each sensor outputs a movement initiation timing signal and an impact timing signal for the corresponding print wire. An electric current to be fed to an associated coil is normally controlled by these timing signals. It is detected whether these timing signals are obtained in a predetermined time period. If not, electric power is continuously fed to the coil or is forcedly cut off so that the timing signals are obtained within the predetermine time period.

摘要： According to a method of adjusting a head gap, a wire dot head is set to a predetermined position of a reference head gap; a printing pattern for detecting printing time is printed by a plurality of pins; reference printing times of respective pins are detected. Next, a test printing is performed with test printing dots previously selected from printing data, and printing time of the test printing is detected. Then, the thickness of the printing media is calculated based on the reference printing time and the printing time of the test printing. At that time, a rule of thumb in which the difference of the printing time corresponds to the difference of the head gap, is used. Then, a shift amount of the wire dot head is calculated for setting the head gap to an optimum value according to the thickness of the printing media, and gap shifting mechanism shifts the wire dot head by the shift amount. This leads to highly accurate detection of the head gap and improves printing quality thereof.

摘要： A wire dot printer has a thermistor that detects the temperature of a print head and a counter that starts counting when the detection temperature exceeds an alarm temperature. The printer can be controlled by switching over between normal-printing and reduced-character-printing in which a reduced number of print wires is used. When the detection temperature exceeds the alarm temperature, the printer will first stop and then control the print head in such a way as to reduce the temperature. Once the temperature drops back down below the alarm temperature, the printer will perform reduced-character-printing for a definite period of time based on the length of time from when the temperature exceeded the alarm temperature to when the temperature dropped back down below the alarm temperature. By increasing the length of time in which reduced-character-printing is carried out, the amount of heat given off by the print head decreases. Furthermore, by basing the time over which reduced-character-printing is performed on the length of time that the alarm temperature was exceeded. It is possible to set the reduced-character-printing time to an appropriate length such that the print head does not overheat and throughout is not excessively impaired.

摘要： In a printer in which a print head and a print medium are moved relative to each other in a spacing direction and in a line-feed direction, the position of the print head in the spacing direction is detected, and the stoppage of the print head during a spacing operation is detected, and the stop position in the spacing direction is stored. When the print head stops, reverse line-feed is performed by a first amount. The spacing operation is then performed in the same direction as before the carriage stopped. A forward line-feed is then performed by the first amount, and then the spacing operation is performed in the opposite direction. If the print head stops again at the same stop positon, an error indication is made. If the print head does not so stop, the spacing operation is continued.

摘要： In a dot-matrix printer including a wire-dot print head having print wires which print dots by impact on a printing medium, and a sensor for sensing the position of the print wires and generating signals indicating the position of the print wires, a parameter is set to determine a printing force with which each of the print wires impacts the printing medium. A control and driving circuit drives the print wire responsive to the signals from the sensors and the set parameter. The combination of the feature of setting a parameter for controlling the printing force and the feature of detecting the position of the print wire enables the control over printing force with a high reproducibility. So printing with an optimum printing force is ensured.
