I use my ix6820 to print fine art prints at home, and have been printing from my one printer for a little over 4 years. After a short break, my printer is not printing pure black, even with the test print looking normal. I replaced the black ink cartridges, and still no help.
Its like it blows out the black, and starts printing a light cyan instead. All of the true blacks have some cyan tone to it, regardless of the paper type.
I cleaned the printer head digitally, but still nothing. Help appreciated!
Please load plain paper into your PIXMA iX6820 and turn your PIXMA iX6820 on.
Please press and hold the RESUME/CANCEL button down, then release the button when the POWER lamp flashes white 2 times.
The RESUME button is the middle button.
Please compare your printout with the example below.
On the page that printed, did a black grid print to the right of |PGBK| ?
Below that, did 3 blue, 3 pink, 1 yellow and 1 gray bars print?
Please open the cover to your PIXMA iX6820. From left to right, what ink tanks are installed? Please provide all text on each label of all ink tanks.
