The symptoms you describe are hardware and not software related so a driver
reinstall will not work.
A dozen deep cleans is excessive and anything over 3-5 is at best a waste of
ink. If a nozzle self test from the printer buttons (not the driver) gives
the same results then it is most likely a clogged/failed printhead. This is
a serviceable part and is also covered under the printers warranty in most
countries (including the U.S.). If out of warranty you can order a
replacement from Canon Parts.
