re: EDIBLE PRINTER

Hmm. I thought the Canon I bought, the MG5620 was meant to be used strictly as an edible image printer. I didn’t think about turning on the printer once a day, but I do blame my problem on leaving those cartridges in place for so long. I have been told since they should be removed and stored in plastic zip bags until the next use.
I will Google What you tried and see if it comes up with some type of solution on how to correct the color. Thank you!
