Could be a few things... I'm busy finishing a video that's aimed specifically at troubleshooting Ecotank printers but due to technical issues I need to reshoot some of the footage and then edit the whole thing so it's going to be a week or so before it's done but don't throw the printer out just...
Oof! If it was second hand and I'm guessing has had some moving around it may have had ink or similar that shorted out some of the electronics. That's gotta hurt though. Hope it wasn't too expensive.
Actually just checked and the WICReset app also supports the TS5000 series so it should be able to do what you need as an alternative to the Canon service tool. You'll need to purchase a WICReset key though.
The instructions @PeterBJ provided for getting it into service mode still apply though.
FWIW: if you can get hold of older firmware updates that don't have the third party crippling function you can extra the necessary file to a memory stick and use that to revert your firmware to an older version.

As waste ink is my bag I can tell you that your caution is well advised... The ET-8550 is supported for it's main waste ink output by the maintenance box that you can change out yourself... BUT, the platen waste ink pad (and counter) are locked away from the end-user and cannot be reset.
Now...
They're considerably bigger now but still full of all sorts of mischief ;)
Odd that it's falling between the cracks but the follow on suggestions from other members cover the bases I would have suggested (and then some) so hopefully you'll find something in those that works. Keep us posted...
Had a quick look and the CX3600 wasn't released in the UK but the CX3650 was. From using that I found that Epson have released a "Universal Print Driver" which is sparkly and new with a release date of 24/01/24...

Let me...
It appears my habit hasn't changed... if anything it's worse...
- You look around your room and realise you have more than 20 working printers in it
- You look around your workspace and realise that there's a further 25-30 broken printers in it
Whoops!
So to summarise and make this less technical... (I've paraphrased the quotes here)
So when you get error code 1752, top up the ink in the cartridge and replace the cartridge and the error will disappear for a while.
This is the error code you want to disable the ink monitoring levels at. Not...
Unfortunately I don't have any of the newer models so can't comment but I'd imagine they'll be very similar in terms of functionality and speed.
As to label costs, we actually get free 6x4" labels from our couriers so we don't buy them ourselves. Once of the few benefits of being a UK operation...
The ones I use are the GK420D and we do have a couple of GK420T's as well but I believe they've stopped making those and pushed to newer so I'm out of date.
The GK420D's are absolute work horses for us though for our shipping labels and various other bits... The T variant are great for colour...
