Abstract
Abstract A standard print mode or a thinning print mode can be selected at will by an input from an operation panel to record image data received by a receiving means section in a selected print mode using an ink jet recording head, And after one page of image recording, a footer mark is recorded on the trailing portion of the recording paper, and sensed by a photo sensor to determine whether or not the ink is present. This footer mark is recorded in the standard print mode without regard to the selected print mode. Thereby, the false detection of the predetermined image recorded on the recording medium, after a predefined amount of image data has been recorded, can be prevented.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
168 words
An image recording apparatus having a first recording mode of recording with a means for recording an image on a recording medium at a predetermined recording density, and a second recording mode of recording with the recording means an image on the recording medium at a lower recording density than said first recording mode, the image recording apparatus comprising: selecting means for selecting said first recording mode or said second recording mode; recording control means for controlling the recording means to record a predetermined image on the recording medium after recording of a predefined amount of image in said first recording mode or said second recording mode which is selected by said selecting means; detecting means for detecting said predetermined image; and processing means for performing a predetermined process based on a detected result of said detecting means; wherein said recording control means controls the recording means to record said predetermined image in said first recording mode, without regard to the recording mode selected by said selecting means.
Claim 2
Dependent Claim
168 words
An image recording apparatus having a first recording mode of recording with a means for recording an image on a recording medium at a predetermined recording density, and a second recording mode of recording with the recording means an image on the recording medium at a lower recording density than said first recording mode, the image recording apparatus comprising: selecting means for selecting said first recording mode or said second recording mode; recording control means for controlling the recording means to record a predetermined image on the recording medium after recording of a predefined amount of image in said first recording mode or said second recording mode which is selected by said selecting means; detecting means for detecting said predetermined image; and processing means for performing a predetermined process based on a detected result of said detecting means; wherein said recording control means controls the recording means to record said predetermined image in said first recording mode, without regard to the recording mode selected by said selecting means.
Claim 3
Dependent Claim
42 words
