Actually, this is exactly the sort of thing you see when ink flow is
restricted, I know I have. The volume of ink flowing at high res is lower
than at normal res. (ml per minute or whatever you call it)
Ink flow is often restricted in the Canons, not in the head but in the
passage from the tank to the head. This is caused sometimes by leaving a
tank out for too long, or an improperly seated tank..

If the printer works fine at hi-res (when all nozzles are being fired),
but
does not at low-res (when reduced nozzles are used) than 'clogging' would
be
unlikely. In either case before I would suggest something as drastic as a
HOT water and alchohol bath, I would want more specific information
(confirmation).

I have a Canon i850 printer that is about 18 months old. It has been
printing fine, but suddenly I am noticing a problem. Whenever I print
an image at the standard or draft quality setting, I have horizontal
reddish colored bars showing up. The space between the bars is the
same size as the bars themselves and the whole image has the bars,
from top to the bottom (think US flag). If I print in high or
grayscale quality, the bars are gone.

I have tried cleaning, deep cleaning, head alignment and nozzle check
all to no avail. I have the newest drivers and the only hardware
change I have made since it last printed ok was the video card, a
nVidia 6800 ultra. I am not really sure if the problem existed before
I changed the card. I don't print all that often and I often I just
print text so it would not be noticed.

Any thoughts?
