Mimaki CJV30-160 showing it's age? It wobbles more lately than it used to when printing.

We have a Mimaki CJV30-160 that's around 15yrs old now. It's been an awesome printer, but for the last month or so I noticed that the machine wobbles back & forth on the base while printing much more than it used to.
It's always wobbled a little, but has gotten worse lately almost like the base has gotten weak. I tightened all the screws as I always check for that when doing maintenance, but it just seems to not help at all.
It doesn't affect the printing, but it scares me because I'm waiting for the legs to give out any day now. Has anyone else seen this? And how did you rectify it? e.g. bracing, strategic reinforcements, etc.
Thanks for any advice!

In some cases, bracing the frame can help a lot. I've also seen people build stands that carry a majority of the printer's weight. 15 years is a good run but might to do some modifications to get 15 more. Gradually those threads will start to pull back, and the metal will fatigue and stretch. Just need to take some of the weight off and see if that helps.
