I’m having the exact same issue. Its a TR4520. Problems from the jump. Today it was having to reset to my wifi, something that should take no time at all. But TWO HOURS SO FAR…still not done. I virtually CANNOT DO IT OR DO ANYTHING with an error that I cannot override. I refill the ink myself….this error always appears, but Im always able to override & move forward…on both printers I have. Now the stop button won’t respond, so, I cannot override the ink error by pressing & holding stop for 7 seconds. I tried all the other things I read, no good. I thought ok let me check the firmware…I can’t get past the STUPID INK CARTRIDGE ERROR. I give up? These issues are so utterly frustrating & not necessary. I won’t ever buy anything with Canon on it ever again. Maybe someone knows other ways to override???
