Digital BW, The Print

My 1280 has been working great...until my big show of course. Suddenly
it started printing a black squiggly line horizontally across the
photo about 1/8 down from the top on a horizontal image.

The squiggly line also appears vertically on text printing from word
files.

I tried several different ink carts.

I've used the cleaning utility and it almost just makes it worse.

I have no idea how to physically clean the print head if that's even
the problem.


Is this an easy fix or am I screwed?

thanks
