Good morning, how are you? I have a problem with a 104 Grizim supply toner. It is the same canon 104 but this is generic. When I joined the client, he took it and did not fit it in his printer. (since I don't have Canon 104 printer) and I test them on my HP 12A printer, what I do is change the parts of Canon 104 to 12A. but I don't know which cover is that of Canon 104 now ... because the client doesn't fit in his printer, to see if they help me to identify how I do to see which covers are the one of 104 .... if they publish photos it would be easier for me to discard
