Hi,

Canon support says:

Issue: Black ink does not print

Solution: Perform deep print head cleaning (Windows) i860

Follow the steps below to perform a Deep Print Head Cleaning (Windows):

Note: After confirming that the cable is connected and the printer is powered on, perform the following.

1. Open the Printers folder.
   
   
   • For Windows XP select 'Start', 'Control Panel', 'Printers and Other Hardware', and 'Printers and Faxes'.
   • For Windows versions other than Windows XP select 'Start', 'Settings', and 'Printers'.
     
     
2. Right-click the printer icon and select 'Properties'.
   
   
   
   
3. Click the Maintenance tab, and then click the 'Deep Cleaning' icon.
   
   
   
   
4. Select the ink tank color(s) for deep cleaning ('All Colors', 'Black', or 'Color').
   
   
   
   
5. Confirm the message, and then click the 'Execute' button.
   
   
6. The Power lamp will blink and print head deep cleaning will start. Deep cleaning completes when the Power lamp stops blinking and lights. (It will take about a minute for the Power lamp to stop blinking and light solid.)
   
   
7. Print a Nozzle Check Pattern to determine if further cleaning is necessary. You may need to perform up to three deep print head cleanings.

Hope this helps and please don't forget to hit the green accept button and leave feedback.

Refer to the following steps to verify the ink tanks are seated correctly:

2. Open the top cover and wait until the print head moves to the center.
   
3. Check that ink tanks are properly seated.

4. Press down on each ink tank until a click is heard.
   
   
   
   
5. Close the top cover. And try to print!

Other choice...

Check ink tank vent hole

The ink tank requires air to flow through it so ink can move from the reservoir to the print heads.

1. Confirm there is no orange tape across the top of the ink tank

2. If the orange tape is as shown in Figure (A), it is properly removed.
   
   

3. If the orange tape is as shown in Figure (B), remove the remaining tape to the level shown in Figure (A).

4. Make sure each ink tank is snapped into the printer.
