Ready? Hold down the Stop/Reset button for about 30 seconds! There you go! I wish I could make it more intense. There just isn't anything else to it. Holding down that button will allow you to go back and scan documents even if you are completely out of ink. (SEE BELOW)
Don't you just love it?
UPDATE 3/22/2011
I feel compelled to update this post with a few more details.
First, you must have the MP Navigator software installed to use my little trick.
Second, the printer needs to be ON. I didn't specify this when I first posted this and I see that a few people had problems.
Third, you need to hold the Stop/Reset button down UNTIL THE LIGHTS START BLINKING. So hold the button down, let the lights come on and start to blink and then after the lights stop blinking, then let go. That may be MORE than 30 seconds. That is why I said "about" 30 seconds above.
That should get you going.
If it doesn't, please don't post that it didn't work. Instead, post what you did and what happened! That is something that I can investigate. It doesn't work means nothing because it does and did work for me. So help me to help you!
Smooches,
Kila
