Just got another one from Ebay, same thing happen when plug in...waiting for return it !!! lost $26 ...shipping. Asking Canonusa again, may be they again dont know how to reset it...
My 2 Canon printer S300 suddenly flash one yellow then one green at the same day. I did try: unplug power, USB, reset catridge but doesnt work...Please help !!!
Try :
unplug it go to another outlet, try it..because I guess it's not the print head problem but the electrical problem
I believe the problem is either with the power switch or the internal power supply.
