PIXMA G7020 faded black ink printing

[naushi]

I have a Canon Pixma G7020 printer. I just purchased a new printhead for black ink. I printed a few pages and the print is now fading already. My ink is full and I have done cleaning but its only getting worse. Please let me know what else can I do to fix it.

You may need to do an ink flush to get it flowing properly.

OK will do and post results - thanks

I get an error message when I try to do the ink flush. the message is printer error 5200. I have no choice but to power off the printer and turn it on again. Ink level is full.

I got no response t the message regarding getting an error 5200 while running the ink flush. However, the black ink works fine.
