Digital BW, The Print

I just finished fixing a clog that I got on my black ink on my 1160 
using MIS FS inks and an MIS CIS unit.  I thought I'd report it to 
the list, since its another case that people might check on if they 
have similar problems.

After not using my printer for a 2 week period, I was getting NO 
nozzles firing on the black ink.  I did the recommended cleaning 
cycles (including printing the purge image) to no avail.  Then I 
tried Windex on the cleaning pad and let the printer sit overnight.  
Still no luck.  

Finally I pulled the black CIS cartridge and checked the ink flow 
from the CIS bottles by attempting to pull ink from the bottom of the 
cartridge using a syringe - and discovered that the ink wasn't 
flowing through the CIS tube from the black bottle at all - it was 
100% blocked.  I removed the tubing from where it connects to the 
black cartridge and using a syringe attempted several times to pull 
ink directly through the tube.  Finally the blockage cleared and ink 
started flowing through the tubing again.  I'm not sure why the tube 
was blocked.

To reinstall the CIS cartridge, I replaced the rubber seal in the 
bottom of the cartridge with a replacement seal (MIS sells these) 
that allowed me to reprime the cartridge using the vacumn unit 
applied to the bottle end of the tubing.  It pulled back some ink in 
the process of creating a vacumn in the cartridge and tubing, but the 
ink did properly flow into the cartridge when the tubing was put into 
the black ink bottle (just as it does on an initial installation of 
the CIS).  I reinstalled the black CIS cartridge into the printer and 
thankfully my black ink is printing properly again.
