Self-timing and self-compensating print wire actuator driver |
摘要 |
There is disclosed an improved drive circuit for a print element actuator wherein the current applied to the actuator has a fast rise mode which is terminated when a predetermined level has been reached. Current is allowed to slowly decay through the circuit until it reaches a second and lower predetermined level. The circuit is self-timing and self-compensating for variations in voltage or actuator impedance.
