Tips for a great answer:
E604 The image memory has a fault.
The RAM has a fault.
The expansion memory is not mounted properly.
E315 The image data coding mechanism has an error.
The coding chip has an error.
The image memory has an error.
If you have installed expansion memory I would turn off your Canon, uninstall the memory and turn on the Canon.
If the error is gone, try to print something.
If you are able to print without error then try re-installing the RAM and make sure it's in correctly.
Then see if the error is gone and try to print.
