Patent number: 11981130Abstract: A printer is provided with a head configured to discharge ink, a fan configured to cool the head, a sensor configured to output a detection signal indicating a state of the fan. A processer of the printer performs decision processing of deciding print control based on a detection signal output by the sensor. In the decision processing, the processor decides a first print control to drive the fan and control printing by the head in a first print mode, when the detection signal does not indicate a failure state of the fan. In the decision processing, the processor decides a second print control to control the printing by the head in a second print mode suppressing generation of heat more than the first print mode, when the detection signal indicates the failure state of the fan.Type: GrantFiled: January 27, 2022Date of Patent: May 14, 2024Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Ko Masuoka, Katsunori Nishida
