Canon head alignment

Archived from groups: comp.periphs.printers (More info?)

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

Great idea. That makes a lot of sense.

Thanks
