I'm not well versed with the Maxify line, but here some general questions to get the ball rolling.
If the printer has any native maintenance and/or adjustment capabilities, have they been run? If the unit can be factory defaulted, has that been attempted? Is the installed ink Canon brand or a third party? Windows? macOS? iOS? Does this happen with only one device or anything that connects to it? Hardwired connection or Wi-Fi? Are there any software/firmware updates pending for the unit? Are the latest drivers installed in the device (computer/tablet/smartphone)?
If worse comes to worse, try reaching out to Canon Customer Support.
