Digital BW, The Print

Hi All

Just an observation.  I have been far too busy at work in the last three months and haven't 
used my 4800 for some time.  Today I finally got around to at a minimum printing enough to 
clear the nozzles.  I fired it up and rather predictably there were issues with the magenta, LK, 
LLk and K (in which I have Eboni loaded) nozzles.  A couple of head cleans and all the K3 
nozzles are singing but the Eboni nozzles are a mess.  I decided to print an A4 page of pure 
black through the colour driver to help clear the K line.  It didn't work and it appears K 
(Eboni) is not firing at all but the A4 sheet is solid green-grey.  The 4800 driver clearly 
underprints some mix of LK and the other inks even when asked to print pure black.  Maybe 
not a surprise to some but it was to me.  Now back to trying to unclog the Eboni...
