Digital BW, The Print

Hi everyone, strange problem with my Epson 2100. I was about to 
print some colour images for someone and nozzle checks showed a 
blocked light magenta. 5 cleaning cycles didn't do it so I injected 
a small amount of Windex and left it during the day.

Came back in the evening, still had a bad nozzle check but it 
cleared with two cleaning cycles and I thought I was in business. I 
printed one of the images - this series happens to be in colour and 
I am using MISPRO inks - and it came out more or less OK but had 
some pizza wheel tracks and one think line down the middle of the 
print where no ink was laid. The light magenta light was also 
blinking indicating the cartridge was empty (despite it being a 
newly placed MIS cart with chip reset).

So I tossed the A3+ sheet of FineArt Pearl :~( reinstalled another 
light magenta cartridge and started to do nozzle checks with plain 
paper. To my great surprise all I get now whenever I try to print 
ANYTHING through the Epson print driver are smudges measuring half 
an inch high or so and running the length of what I print. It looks 
as if every ink cartridge is simply bleeding onto the paper.

The strange thing is if I print something through QTR I get the 
image appearing more or less normally plus at this point some fine 
lines of colour that I hope or guess are residual from my huge ink 
smudges. So it looks as if the problem only happens if the printer 
is being driven through the Epson driver. 

As a result I uninstalled an reinstalled the printer and driver 
software but unfortunately no change. Anyone has any ideas on this? 
I am stumped.
