I look at these occasionally, but they aren't the main type of machine I work on. I've been doing research here and elsewhere, there is mentioned a list of things it might be, but not really a way to test which is which. Basically after the first print it will say 'filling ink from tank' sometimes for quite a while, then make the next print. It does this between each print, then eventually go into code.
I have so far cleaned the encoder, cleaned & oiled the rail, checked the belt for damage & clean contacts and reseat printhead. I don't have any fancy equipment to check the ribbon cable for cracks or continuity. They said it might be a cutter or main board. I don't have such things lying around and they are kind of expensive just to try out. How would you figure out which one? Additionally what if it might be some kind of ink sensor or pump problem ? Canon is rather vague on all of this. I would be greatly appreciative if there's an expert who could shed light on this dilemma.
