Impact printer temperature control device |
摘要 |
In a control device for an impact printer for performing a printing operation at a first printing speed, a temperature sensing element, provided such that the temperature of an electromagnet unit can be directly or indirectly detected, is operated at a first temperature and restored at a second temperature lower than the first temperature. A controller changes the printing speed to a second printing speed lower than the first printing speed when the temperature sensing element is operated, returns the printing speed to the first printing speed when the element is restored, and changes the operating speed to a third printing speed lower than the second printing speed when the element is operated for a predetermined period of time, whereby the printer is made high in reliability.
