PIXMA TS4320 Print offline error, serial number invalid error

Hello,

I just got the TS4320 and it is a nightmare to set up. It took forever to get the app to work and it keeps saying my printer is offline when it is on. I keep trying to link my account/log in and it just keeps giving me errors saying to log in from the home screen. I am at my wits end here. I don't know what to do. I tried to register the printer but it said invalid serial number. Is someone able to help me?

Greetings,

Its not clear whether you're having a problem registering your device in the MyCanon portal or in the Canon print app 🤔?

Since you are having issues, I suggest you contact Canon support. 1-800-652-2666

Here's all the information I found on pixma cloud Link.

Give support a call. I'm sure they'll be able to assist you.

I honestly don't know. I can log into the MyCanon account just fine on the computer but not in the app. I'll see if I can call tomorrow. Thank you
