Trying out a new printer and not satisfied got permission to return for refund. Problem: in testing printer I was on my last test print and got an ink out warning, void warranty and so forth...so figured no harm would be done to printer if I bypassed warning and printed one more 8 1/2 x 11 print. Printed okay. Can I reset the warning to function again as the tank is not transparent and how would you tell if it were out of ink, and also when printer is returned will they see this and not take it back?
