Hey @whiskeyguy,
I am not a services agent so this is not official advice here, but I’ve seen a few creative (and surprisingly effective) community fixes here over the years for exactly this issue.
If your tank’s just intermittently losing contact, a quick first step some users have taken is to slightly build up the copper pads with tiny solder blobs to restore consistent contact pressure. Here’s one thread showing that approach: Form 2 Copper Finger Tank Non-Contact Hack. the user basically tinned the contact points with a bit of solder, which helped the fingers seat more firmly against the tank chip.
Another discussion that goes into detail about that method (and other alignment tweaks) is Replacing the Tank Spring Finger. In that one, people mention cleaning and lightly bending the spring fingers for better reach, and one user notes success after adding solder to the worn contacts.
Then there’s the experimental fix titled “this is definitely going to void your warranty”. The poster actually soldered wires directly to the tank connector and bypassed the broken spring contacts entirely with some jumpers. It worked, and one of our engineers was impressed, so it was equal parts risky and impressive.
If you try anything along these lines, just keep in mind that any modification to the contact assembly will void the warranty and calibration can be tricky if the carrier alignment changes. But if your printer’s long out of warranty anyway, these threads are worth a read for reference.
