I'm trying to add some new papers to test, and the MCT tells me the maximum number of media types that can be added is 127. I only have six showing in the MCT, version 7.03 on 10.13.6.
From the printer control panel, I can see 40 custom media types that we've created over the years, many of which we still use.
From the MCT, I have the option of deleting only the six custom papers that show, but not any of the Canon genuine media types. Slightly stumped.
