Canon IP 6600D Photo Printer

[Sebring291]

My IP 6600D has given me great service for quite a few years but recently something has changed.
I always buy compatible inks and have never had a problem with any of them not working, but my more recent problem is this.

When you click the cartridge into the printer head a little LED in the head used to light and the light would shine up through the cartridge showing all's well and it would flash to indicate when it's empty.

Now I am in the dark.
None of my more recent purchases will show this indication. There is just no light whichever ones I use. I have put used ones back in to check and the light returns, so it's a function of the cartridges not the print head.
I still have two that have not been changed recently that are lit up.

Can someone please tell me why this is happening? Is it a cut back by the cartridge maker not triggering the LED\?
I have tried several suppliers and it is not just one maker/supplier causing the problem, unless, of course, all replacements come from one source and just get re-branded.
Is there anything I can do to get this sorted?
For info, the ink levels still show on the screen, but the lights are very useful.

Thanks in advance.

It could be that a firmware or driver update is causing it to now sense nongenuine ink.
