PIXMA MG4250 How do I remove ink cartridges following a 5B02 error?

[battlebus]

My ink absorber is full - I've over-ridden it many times and now I just get a 5B02 error - contact the service centre.

This is a cheap printer so I bought a new similar model to replace it so I can carry on using the ink cartridges - which are almost as expensive as the printer!

But now I can't get the old cartridges out. The printer will not let me get at them.

Any ideas how I can either get the printer to put them in a removable position?

Is anyone from Canon here? Can anyone help me resolve this issue? If I have to force it open, it will become a useless piece of landfill.

That unit isn't supported by Canon USA. We don't have any documentation on it. You'll need to reach out to Canon in your country for help. You can find Canon Global at https://global.canon 

The documentation we do have on that error (for a different model) is HERE.
