Hi Starbright,
First, a test should be performed of your PIXMA MX479. The Nozzle Check pattern shows if each print head nozzle is operating properly. Please perform the following steps to print a Nozzle Check pattern:
1. Load letter-sized, plain paper in the rear Tray.
2. Press the SETUP button.
3. Press the left or right button until [MAINTENANCE] is displayed in the LCD, and then press OK.
4. Press the left or right button until [Nozzle check] is displayed in the LCD, and then press OK. The nozzle check pattern is printed. Please compare your printout to the example that is at the bottom of this post.
If the page prints incorrectly, printhead cleanings should be performed. Please follow the instructions below to clean the printhead:
1. Press the SETUP button.
2. Press the left or right button until [MAINTENANCE] is displayed in the LCD, and then press OK.
3. Press the left or right button until [CLEANING] is displayed in the LCD, and then press OK.
After 3 or 4 cleanings, print another test page.
Does the test page print correctly?
