How do I reset Canon waste ink counter?

Occasionally, some users will experience the error on their printer where it stops printing and all the lights start flashing. Different printer models may have different descriptions of this error, but it seems to be generally described as a ‘Unknown Printer Error’. In fact, numerous users in the internet community believe that this error is most often experienced when the printer has reached a condition where it thinks the ink waste pads inside the printer are full. That’s right - all that ink you lose in cleaning cycles and priming new cartridges has to go somewhere, and your Epson printer keeps track of roughly how much ink it has dumped into some large absorbent pads in the base of the printer!
