Image forming apparatus, image forming system and recording medium

An image forming system including an image forming apparatus and an information processing apparatus configured to communicate with the image forming apparatus, the image forming system further comprising:

• a forming section provided to the image forming apparatus and is configured to form a color image,
• a correction section configured to measure at least one of a position and a density of a test pattern formed by the forming section and perform a correction function for adjusting an image forming condition based on the measurement,
• a determination section configured to determine whether a color condition is satisfied, the color condition being satisfied if print data, which is an object of a print request, includes color page data, and
• a control section configured to selectively perform a first mode or a second mode when the print request is received and a correction execution condition is satisfied,
• wherein, in the first mode, the forming section is caused to print the test pattern and the correction section is caused to perform the correction function, before a printing process begins in response to the print request, and
• wherein, in the second mode, the forming section is caused to form the test pattern and the correction section is caused to perform the correction function after the printing process has begun in response to the print request and at least before a printing process for the color page data begins, on condition that the determination section determines that the color condition is satisfied, whereas the forming section is not caused to form the test pattern and the correction section is not caused to perform the correction function, in the second mode, if the determination section determines that the color condition is not satisfied.

A non-transitory computer readable recording medium storing instructions that, when executed, cause a computer of an information processing apparatus to perform a method comprising:

• determining whether a color condition is satisfied, the color condition being satisfied if print data, which is an object of a print request, includes color page data, and
• selectively instructing an image forming apparatus to activate a first mode or a second mode when the print request is received and a correction execution condition is satisfied, wherein the image forming apparatus is configured to form a color image, measure at least one of a position and a density of a test pattern and perform a correction function for adjusting an image forming condition based on the measurement,
• wherein in the first mode, the image forming apparatus is caused to print the test pattern and to perform the correction function before a printing process begins in response to the print request, and
• wherein in the second mode, the image forming apparatus is caused to print the test pattern and to perform the correction function after the printing process has begun in response to the print request and at least before a printing process for the color page data begins, on condition that the color condition is satisfied, whereas the image forming apparatus is not caused to form the test pattern and is not caused to perform the correction function, in the second mode, if the color condition is not satisfied.
