Hi vati999,
First, please make sure all of the ink tanks in your PIXMA TR8520 contain ink.
Next, please load letter-sized paper in the cassette of your PIXMA TR8520 and follow these steps:
1. Please tap the gear at the bottom of the display of your PIXMA TR8520.
2. Tap Maintenance.
3. Tap Print nozzle check pattern and then tap Yes.
A test page will print. Please compare your printout to the example below.
Does a black grid print to the right of |PGBK| ?
Is the grid complete? or are there missing boxes within the grid?
Below that, did 2 blue, 2 pink, 1 yellow and 1 gray bars print?
