It's a printhead tilt fault (Assuming you got the code in the body of your post because the one in the subject line is different and I am fairly sure doesn't exist.)
The 23709 isn't important, it is the page count the machine had printed when the fault occured, so eliminate it when you do a search.
My printer shows an error code of 91.720.00:23079
What does this error code mean and how can I correct it?
