Ink Cart Spring Replacement on 9900

Does anyone have any experience with replacing the springs (or entire mechanism) that locks the ink carts in place on a 9900? I have two slots where the spring seems to not be so springy anymore and occasionally throws a cart reading error. Thoughts?

Thanks!

It’s a CSIC connector. Compass Micro has them (but you need to call them for it).

It’s relatively simple to replace if you remove the ink bay and then ink bay cover/back. The maintenance manual (available at https://groups.io/g/EpsonWideFormat) is recommended.

best,
