Digital BW, The Print

Help,

 I am having problems with my 1160. I started having problems getting a 
good nozzle check (I never do). At the same time ink track marks, from 
the rollers, started to appear on my paper.  I cleaned the inside of 
the printer and run several sheet of paper through until the paper came 
out clean. But, as soon as I cleaned the heads and did a nozzle check 
and ink tracks would reappear. I could never get a good nozzle check. 

If the nozzles are clogged will it spray ink all over the inside of the 
printer?

Thanks
