Image forming apparatus and calibration processing method and calibration processing program product for image forming apparatus

A calibration processing method for an image forming apparatus comprising:

• image forming means for performing an image formation process;
• an operation panel that displays predetermined information;
• and control means for controlling the image forming means and the operation panel, in which the control means performs a calibration process in the image forming means under a predetermined trigger condition, the method comprising:
• interrupting the execution of the print job by the control means when the predetermined trigger condition occurs during execution of a print job;
• allowing, by the control means, the operation panel to display an error and waiting for a selection of either performance of a calibration process or continuation of the print job to be executed;
• controlling, by the control means, when the performance of a calibration process is selected through the operation panel, the image forming means to perform a calibration process and then re-executing the interrupted print job;
• and
• re-executing, by the control means, when the continuation of the execution of the print job is selected through the operation panel, the interrupted print job without performing a calibration process.

A calibration processing program product for an image forming apparatus that allows a computer to perform a calibration process in an image forming apparatus comprising:

• image forming means for performing an image formation process;
• an operation panel that displays predetermined information;
• and control means for controlling the image forming means and the operation panel, in which the control means performs a calibration process in the image forming means under a predetermined trigger condition, the product allowing the computer to perform the steps of:
• interrupting the execution of the print job by the control means when the predetermined trigger condition occurs during execution of a print job;
• allowing, by the control means, the operation panel to display an error and waiting for a selection of either performance of a calibration process or continuation of the print job to be executed;
