[0016] Next, refer to Figures 1 to 5 A first embodiment of the present invention will be described.

[0017] (The overall structure of the printer)

[0018] figure 1 is a cross-sectional side view showing the overall structure of the printer 1 . Throughout the description, the terms "above", "below", "front", "rear" etc. are used assuming that the printer 1 is located in the direction in which it is intended to be used. More specifically, in figure 1 In , the right and left sides are the front and back sides, respectively.

[0019] The printer 1 includes a casing 2 . A sheet feeding tray 4 is located at the bottom of the cabinet 2 . A plurality of sheets 3 of recording media such as paper are stacked in a sheet feeding tray 4 . A pickup roller 5 is located above the leading edge of the sheet feeding tray 4 . By rotating, the pickup roller 5 feeds the uppermost sheet 3 in the sheet feeding tray 4 to a pair of registration rollers 6 located downstream in the sheet feedi...

[0060] Image 6 is a flowchart showing steps in job execution processing according to the second embodiment. In the first embodiment described above, the CPU 30 determines whether or not the condition that correction is not required is satisfied based on all print jobs recorded in the print queue. Processing performed in the second embodiment is similar to that described in the first embodiment, except that the CPU 30 determines whether the condition that correction is not required is satisfied based only on the current job. Therefore, the following description of the second embodiment focuses only on this point of difference, while omitting descriptions that overlap with the first embodiment.

[0061] Image 6 is a flowchart showing steps in job execution processing executed on the printer 1 under the control of the CPU 30 . The CPU 30 sequentially executes this job execution processing for each print job registered in the print queue.

[0062] If the CPU 30 determines in...

Abstract

Provided is a printing device having correcting function. A correction unit executes a correcting function for measuring at least one of position and density of a test image in response to a correction instruction and correcting an operation setting of a printing unit based on the measurement result. Print data includes correction requiring data that is required to execute the correcting function by the correction unit before an image corresponding to the correction requiring data is printed. A determining unit is configured to determine whether or not at least one of two conditions is satisfied. One condition is such that a ratio of a second numerical value represented by the correction requiring data to a first numerical value represented by the print data is less than a first reference value. Another condition is such that the second numerical value is less than a second reference value. When the determining unit determines that the at least one of two conditions is satisfied, the control unit bypasses the measurement by the correction unit even if a receiving unit receives the correction instruction.

Description

technical field [0001] The present invention relates to a printing apparatus having a correction function for measuring deviations in position, density, and the like of a formed image and adjusting operation settings based on the measurement results. Background technique [0002] For example, the conventional printing apparatus disclosed in Japanese Patent Application Laid-Open No. 2009-134149 implements a correction function for measuring deviations in position, density, etc. of a formed image and adjusting operation settings based on these measurements . Specifically, on condition that a print request for performing a color print operation and a correction command are received, a conventional printing apparatus having the correction function performs a correction process before performing a print operation according to the print request. [0003] However, when the above-mentioned conditions are satisfied, the conventional printing apparatus always executes correction proc...
