Classification: CPC B | IPC B

Claim 7:
8. An image recording apparatus, comprising:
a power source;
a drivable device configured to be driven by power supplied from the power source;
a head;
a motor configured to be driven by power supplied from the power source;
a carriage, on which the head is mounted, the carriage being configured to move by a driving force transmitted from the motor;
a sensor configured to output a signal corresponding to a behavior of the carriage;
a memory; and
a controller configured to conduct a recording process, in which the drivable device conveys a recordable medium and the head records an image, the controller being configured to, in the recording process,
control the power source to generate a first driving current to drive the drivable device, the first driving current being variable,
control the power source to generate a second driving current to drive the motor, the second driving current being variable,
set a current calculated by subtracting the first driving current from an allowable current to the power source as a limitation current, the limitation current being a maximum current allowed to be supplied to the motor,
control the power source to supply the first driving current to the drivable device to drive the drivable device and simultaneously supply the second driving current not exceeding the maximum current to the motor to drive the motor, and
when the controller determines, based on the signal output from the sensor, that the behavior of the carriage satisfies an error condition,
on a condition that the drivable device has completed a targeted conveying action, issue an error alert, and
on a condition that the drivable device has not completed the targeted conveying action, control the motor to cause the carriage to continue moving without issuing the error alert,

wherein, when the controller determines that the behavior of the carriage satisfies the error condition based on the signal output from the sensor, and on a condition that a time stored in the memory since the drivable device completed the targeted conveying action has not yet elapsed, the controller is configured to control the motor to cause the carriage to continue moving without issuing the error alert.
