Rebooted all devices: iPhone, MacPro & printer. Reloaded printer driver. Nothing will clear the problem.

Hi Jwarnett,

Let's perform a test of your printer:

1. Please press the Home button on your PIXMA TR7520 one time.

2. Tap gear icon at the bottom of your printer's display.

3. Tap Maintenance.

4. Tap Print nozzle check pattern.

5. Tap Yes.

Does the test page print?

If not, what error appears?

Thanks for your response Patrick. Before I received the response I did a full shutdown and cold start on router, computer and printer which ultimately cleared the problem. I will, however, retain your recommended procedure in the event the problem occurs again.
