Ink jet recording apparatus

摘要

An ink jet recording apparatus includes a recording head configured to discharge ink onto a recording medium, a carriage on which the recording head is mounted and which is configured to make a reciprocating movement, a cutter unit mounted on the carriage and configured to cut the recording medium, a detection unit mounted on the carriage and configured to detect a distance to the recording medium, and a control unit configured to control an operation of the recording apparatus. The ink jet recording apparatus includes a first process for detecting an amount of a change in the distance to the recording medium by the detection unit when the recording medium is cut by the cutter unit, and a second process for detecting the distance to the recording medium by the detection unit while the cutter unit is retracted if the change amount equal to or more than a predetermined value is detected in the first process. The control unit determines that the state of the recording medium is abnormal when the distance to the recording medium detected in the second process is equal to or less than a predetermined value.

1. A recording apparatus comprising:
a recording head configured to record an image on a recording medium; a carriage with the recording head mounted thereon and configured to make a reciprocating movement; a cutter unit mounted on the carriage and configured to cut the recording medium; a detection unit mounted on the carriage and configured to detect a distance to the recording medium; and a control unit configured to perform a first process, wherein in the first process, the detection unit detects the distance to the recording medium while the carriage moves to cut the recording medium by the cutter unit, wherein in case the amount of a change in the distance detected by the detection unit within a range in a direction of the movement of the carriage is equal to or more than a threshold value, the control unit performs a second process, in the second process the detection unit detects the distance to the recording medium by the detection unit while the carriage moves and the cutter unit is retracted, and wherein the control unit determines that the state of the recording medium is abnormal when the distance to the recording medium detected in the second process is equal to or less than a predetermined value.
