Abstract
A liquid discharge head includes: a discharging module which has a discharging drive element and a discharging heater capable of being electrically connected to the discharging drive element; a circulating module which is arranged in pair with the discharging module and has a circulating drive element and a circulating heater capable of being electrically connected to the circulating drive element; and a pulse width controller which differentiates a discharging pulse width for controlling the discharging drive element to a conductive state from a circulating pulse width for controlling the circulating drive element to a conductive state.
Claims18
A liquid discharge head, comprising:
- a discharging module for having a discharging drive element and a discharging heater capable of being electrically connected to the discharging drive element;
- a circulating module for being arranged in pair with the discharging module and for having a circulating drive element and a circulating heater capable of being electrically connected to the circulating drive element;
- and
- a pulse width controller for differentiating a discharging pulse width for controlling the discharging drive element to a conductive state from a circulating pulse width for controlling the circulating drive element to a conductive state.
A liquid discharge apparatus, comprising:
- a liquid discharge head;
- a carriage for mounting the liquid discharge head and for reciprocating in a main scan direction;
- and
- a conveyance roller for being provided below the carriage and for conveying a discharge target medium in a sub scan direction,
- wherein the liquid discharge head comprises:
- a discharging module which has a discharging drive element and a discharging heater capable of being electrically connected to the discharging drive element;
- a circulating module which is arranged in pair with the discharging module and has a circulating drive element and a circulating heater capable of being electrically connected to the circulating drive element;
- and
- a pulse width controller which differentiates a discharging pulse width for controlling the discharging drive element to a conductive state from a circulating pulse width for controlling the circulating drive element to a conductive state.
