Vista Error "No Disk" 0xc0000013

Does anybody know what this is?

0xc0000013 parameters 0x761692A0

that is the error code and the first parameter but this proved
fruitless in a google search

all i can say that might be happening to cause this, is the printer
seems to try and "wiggle" in standby. (LOL, funny images) apart from
that nothing is apparent, i have tried changing drive names, but i
have not plugged a new device in, nor installed new programs for 4
days at least. (PC been on all that time with no problems)

Please help
