Cause
The remaining ink level in one of the ink tanks may have reached the lower limit line shown on the ink tank.
What to Do
To check the remaining ink level, visually inspect the remaining ink in the ink tank.
If the remaining ink level is below the lower limit line, refill the ink tank with the corresponding color of ink.
If printing is continued when the remaining ink level is below the lower limit line, the printer may consume a certain amount of ink to return to printable status.
To continue printing, press the printer's OK button.
After this operation, the remaining ink level notification function will not operate.
To reuse this function, refill each color of ink to the upper limit line shown on the ink tank and press the printer's OK button for at least 5 seconds.
If any ink tank is not refilled to the upper limit line, a significant error may occur in the accuracy of the remaining ink level notification function.
Please be advised that Canon shall not be liable for any malfunction or trouble caused by using non-genuine Canon ink.
