I read about the Pixma cycling issue and I have the same trouble with my MX452. It worked fine until yesterday, August 22, 2022. I started printing wirelessly and after the first page printed the printer started beeping and cycling on and off. It will not remain on. I read many of the posts about this same issue on other Pixma printers and tried many of the offered solutions including powering off and recycling both my modem and router as well as disconnecting the printer from power and the USB cable to my iMac... nothing worked. Any additional suggestions to correct this issue will be appreciated. The Canon service message from June 2022 did not include the MX452 in the list of affected printers.
