Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To obtain simple and effective recovery sequence for preventing a decrease in printing quality after wiping by preliminarily discharging after a time of several seconds after the wiping, and stabilizing the printing quality of writing. SOLUTION: Suction recovering and wiping of normal recovering treatments are executed for an object head (S1 to S2), and whether the mounted head is color or not is judged. If it is colored, three seconds are waited, while if it is not colored, two seconds are waited (S3 to S5). In all cases, the head is preliminarily discharged after the waiting time is finished. Fault discharge or non-discharge due to clogging of a discharge port of the head is eliminated by a series of the recovering treatments, and whether it is recovered or not is judged (S6 to S7). If it is recovered, it is transferred to a print mode (S8), but if it is not recovered, it is again returned to the original, and the series of recovering treatments are repeated. Thus, clogging of the discharge port is easily eliminated.
