Abstract
A liquid discharge apparatus comprises an energy generating element for generating energy to be utilized for discharging liquid, a wiper for wiping in succession plural discharge ports for discharging liquid, utilizing the energy generated by the energy generating element, control device for starting liquid discharge, utilizing the energy generated by the energy generating element, among the plural discharge ports, in succession from a discharge port immediately prior to being wiped by the wiper and from a discharge port in the vicinity of the immediately prior discharge port at the downstream side in the wiping direction by the wiper.
Claims10
A liquid discharge apparatus comprising:
- an energy generating element for generating energy to be utilized for discharging liquid;
- a wiper for wiping in succession plural discharge ports for discharging liquid, utilizing the energy generated by said energy generating element;
- and
- control means for starting liquid discharge, utilizing the energy generated by said energy generating element, among said plural discharge ports, in succession from a discharge port immediately prior to being wiped by said wiper and from a discharge port in a vicinity of said immediately prior to being wiped discharge port at a downstream side in a wiping direction by said wiper.
A discharge recovery method for a liquid discharge apparatus, the method comprising:
- a wiping step of wiping in succession plural discharge ports for discharging liquid with a wiper, utilizing the energy generated by an energy generating element for generating energy to be utilized for discharging liquid;
- and
- a discharge step of starting liquid discharge, utilizing the energy generated by said energy generating element, among said plural discharge ports, in succession from a discharge port immediately prior to being wiped by said wiper and from a discharge port in a vicinity of said immediately prior to being wiped discharge port at a downstream side in a wiping direction by said wiper.
