The LED blinking is a error code status. it should help pin-point what causing the error. If 4 blinks=ink cart, if 5=print carriage, it should recycle the blink code. Hit resume/cancel button and that should clear the error, then retry any prints if possible otherwise the blink code returns. if the blink sequence is different, please note it maybe I can decipher it further, but be sure of the sequence.
