Print head is either clogged or cooked. Since you are still getting good
prints at high quality settings, it may just be clogged. Remove the print
head and soak the head in hot water and Windex for 15 min, then wipe
clean.
If that doesn't do it you can try a cleaning kit like the ones sold at
www.inkjetsaver.com . These will clear ANY clog.
It's best not to use the printer in this condition.



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?
