Im taking the opposite position here I dont think they can do that or would want to either,
why would Canon want to disable one single colour head from the cleaning routine, think about it for a minute.
Sure if they did that then that single head would be starved of ink leading it to a total burn out,
where would that leave Canon in the courts, like we deliberately disabled the ink to the head that burned out your honour !
The purge unit is mechanical and is not subject to individual commands it either performs a cleaning service or it doesnt,
the print owner has the choice as to which set of ink heads they want to clean not the firmware,
it just looks like Canon want to scare the hell out of the owner for daring to use refilled cartridges,
only time will tell thats for sure..
