Sounds like the memory stick is loose.
If you just received it, that machine has a one year warranty on it.
Call and Xerox will send someone out, or else they will replace it.
Your going to love that printer. WOW what print quality it has.
But your problem most likely was due to shipping and something coming lose.
Call 1-800-835-6100, follow the prompts, they will help make it right.

That is a cyan, ( blue) ink stick fault. What is happening is that the cyan ink sticks are not advancing down the ink loader properly.
Open the area where you load the ink and you probably have a cracked, twisted or otherwise stuck ink stick, the code you are reporting specifically refers to the cyan sticks. If you have to remove them, take a screw, a drywall screw is best, and twist it into the sticks and slide it back and out, then replace them or add new ones. But thats your problem.
