I'm trying to run an ink density calibration but when I print the
paper will just travel all the way through the printer without
printing or it will just start to go through and stop.  The first
calibration I ran printed just fine but now the second print hangs or
goes all the way through.  Sometimes if I cancel the print job and
reboot it will work but most times the same thing happens.  I just
cancelled the job and tried to print an image and it printed just fine
so I tried to print the calbration print again and it hangs.  However
sometimes images have the problem too.  My 1280 used to do it too.  I
can't determine a pattern to the problem.  When I print with Qimage
through the Epson driver it always prints correctly.

Has this happend to anybody?

Thanks,

Tom
