Yes, unfortunately.

Once a print head gets clogged I've found no remedy other than to
replace it. I've tried alcohol with swabs, even acetone.

You have to decide whether it's cost effective to buy a new head,
or a new printer. In your case, if nothing else is wrong with the
printer or it's other multi-function features it may be better to
buy the print head. I see one on Amazon for $70 that is
refurbished by Cannon.

it's cheaper to buy the whole Canon printer from WalMart($35) than to buy a
single print cartridge,and you need both color and black cartridges.


You can help prevent a clogged head by leaving the printer on all
the time, so it can do it's self cleaning everyday. Did you
regularly turn yours off?



I wonder if an ultrasonic cleaner would unclog a printhead?

If you leave your printer on all day,the heads stay uncovered and dry out
faster. when the printer is off,the heads are parked and covered by a cap.
that's why new ink cartridges don't dry out in the packaging while on the
shelf.
Hi,
My printer stays on all the time and standyby power is only 3 Watts. I
never had problem and it seems it does less self cleaning and ilk lasts
longer. I used Epson, HP, Lexmark, Canon and always kept them on.
