Of course, the particular printer is not the real question, which is are aftermarket inks fade resistant. The cost of UV additives is trivial at the percentages added. The formulation of inks is commonplace information, do you think that Canon has a private factory in China, my guess is no... as with many things relabeling is a common practice.
So why do prints fade, is it UV or Other factors? "Air fade of an inkjet photo print is caused by direct contact with airborne gases and pollutants, primarily ozone." High humidity "dissolves" pollutants and the degradation reaction is accelerated.

"The only difference that we have found in all honesty is that the genuine ink holds up better long term under harsh UV conditions. In normal home situations, the
generic ink photos will remain unchanged for many years"https://www.inkhub.com.au/ink/common-myths-about-generic-printer-cartridgesPaper makes a difference as demonstrated by RedRiver Paper Company:

https://www.precisioncolors.com/PC42cref.htmlI have had no problem with fading, Lucky perhaps. I do put a microfilm of paraffin on the prints using the flat short brisel paint applies found in Walmart or Lowes etc. This is done to make the prints water-resistant and perhaps some Ozone resistance [if blocked by wax Ozone can not attack the ink].
" does not provide UV protection" However, the wax can provide a barrier to humidity and air pollutants which cited above are significant contributors to fading.
https://forum.luminous-landscape.com/index.php?topic=65647.0As with many crafts what works for one may be used in another. Art Candles are susceptible to fading, but there are additives to protect the colors from UV. The same can be applied to the Paraffin that I use for my prints and so
thank you Imageandart for this thought-provoking educational question, in the future this UV additive will be mixed with the paraffin coating. [8oz for $12 also from Amazon]
