I've had an HP PSC 1510 All-in-One Series printer for quite a long time now. A couple weeks ago, I installed a new black-ink cartridge as usual. After recognizing the new cartridge the printer, as usual, printed a test page which I'm supposed to scan. AFAIK, this is done to adjust the printer to get the best result when printing, so I go ahead, put the test page in the scanner, hit the "Scan" button... and nothing happens. Now, every single time I turn the printer on, it tries to print the test page again. I've tried several times to scan that page, but nothing happens. Any idea on what may be the problem and how can I solve it? Thanks in advance.
