摘要:
An ink-jet printing apparatus and suction recovery control method which can minimize reduction in throughput while maintaining a printhead in the most appropriate condition, and can reduce the amount of wasted ink. According to the suction recovery control method, a printing period of predetermined printing operation is timed, and the number of print dots formed by discharging ink from a printhead during the predetermined printing operation is counted. Based on the timed printing period and counted number of print dots, the number of print dots per unit time is calculated. Then based on the calculated number of print dots per unit time, timing of suction recovery operation is determined, and suction recovery operation of the printhead is performed according to the determined timing.
