My Canon S630 has an error code that I believe is 'waste tank full". It blinks 7 orange and 1 green. I found some information on how to reset the counter, but it doesn't seem to work. I can remove the head, clean the contacts and reset it to print a page or two but then the error reoccurs.
Can someone verify the process to reset the counter and also how exactly do I clean or empty this reservoir?
