So I am sorta new to printing on Edible sheets. It started good then all of a sudden my reds were orange. So i changed out my red and yellow cartridge and it worked great. Then before that cartridge was empty it happened again. Do cartridges go bad, as in the chip? I know they can dry out but I dont think that is the issue since it was used daily and always had at least a quarter of tank. I print about 5-10 images a day and in 30 days I have been through 3 cartridges of yellow. I have seen companies sell cartridges and say "refill 3 times". Why only 3 times?
Did you try shaking the cartridge?
I would contact the company that makes them. I haven't had that problem so I can't personally advise you. I do know it SHOULDN'T be happening!
