I just got a Canon Selphy CP910 and I love it when it works. Unfortunately, it says "no paper, or cassette incorrectly inserted" EACH TIME I try to print! I have to pull out the tray and reinsert it a few times to get it to work. It did this right out of the box. I'm not a tech, but I think if there's a sensor involved it may be not working right. I've had to do this at least 50 times and it takes the fun out of what otherwise woukd be a really great product.
Have you run into this before and can you help me?
