Maintaining the Ink Quality
This printer automatically mixes the ink at fixed intervals to keep the ink density even.
You can also disable this function by unchecking the Execute ink quality maintenance automatically check box in Custom Settings of the Canon IJ Printer Utility pop-up menu. You should check this check box when using the printer.
Note that the ink density may become uneven when this setting is disabled. Therefore, when you disable this setting, be sure to execute the following operation about once a week.
The procedure for executing ink quality maintenance manually is as follows:
Ink Quality Maintenance
Select Test Print from the pop-up menu on the Canon IJ Printer Utility
Click Ink Quality Maintenance
Click OK when a message appears.
