"Why won't my device power on when I press the power button?" için yanıtMy rarely used, and always plugged in PC, I tried to print with device I had used before. No go. Today, I was going to try again..,had been plugged into wall all night. But no tiny blue light! When I tried turning it on, tkk flick on adjoining tiny blue light it instead has given only 5 yellow blinks each time.
