ABSTRACT:
When there are two kinds of caps that protect nozzle faces of print heads—a protective cap with no suction mechanism and a suction cap with a suction mechanism—and if a time during which the print heads are left idle is within a predetermined time, each print head protected by the protective cap performs 5,000 idle ejections during the idle ejection operation executed prior to initiating a printing operation. Each print head protected by the suction cap performs 100 idle ejections during the idle ejection operation. By setting the number of idle ejections for print heads protected by the protective caps to be greater, it is possible to keep all the print heads in good condition at all times whether they are protected by the suction caps or protective caps.
