Digital BW, The Print

I think it's pretty much safe to say that I have next to no ink in the  
K line.  Where the line disappears from view towards the cartridge is  
clear as well.  If I clean the damper (now that I know what it is!)  
and there is no ink in the line, will the printer still be able to  
draw ink through (assuming no other blockages)?  I assume "yes" as  
that's how the printer was delivered - with empty lines.  But if the  
damper was blocked, I would expect full lines, i.e. it pulled ink  
through until it blocked...
