Canon head alignment

[BF]

Does anyone know what it means if the rectangle bars are not complete,
in a Canon I960 head alignment? I know how the alignment works but the
bars are not completing in one color. A nozzle check shows no problem
but it seems like there isn't enough ink to make the bars solid. Again I
understand about picking the best for proper alignment. The top starts
out broken.

Thanks

We have an i9100 and just recently had the same problem. I did the head
cleaning and it didn't seem to work. I finally took the print head out
of the printer and removed the ink cartridges. When I looked closely at
the rubber seats around the port where the ink enters the head from the
cartridge they looked to be slightly caked up with ink. I took some
Q-Tips dowsed in water and cleaned the seat areas well then reinstalled
the cartridges and print head. It has worked great ever since. I think
that after awhile this area gums up enough to keep the ink tank from
making a tight seal. This in turn lets in small amounts of air that can
sporadically interrupt the ink flow to the head. We have printed
thousands of photographs and other documents with the printer over the
last year so it didn't surprise me that this might occur. Although we
use compatible cartridges I think the same thing could easily happen
with the Canon branded cartridges.

Great idea. That makes a lot of sense.

Thanks
