"Cannot Detect" caused by ink ejection problem

I get a "Cannot detect" error on my MFC-J5919DW for BK, C, M.

When I remove the ink cartridges, I see that the there are small sliding mechanisms below the cartridges which are supposed to go back, once the cartridges are removed.

This happens only for yellow (therefore only the error on BK, C, M).

Any idea how to get these moving again? Slight push/pull has no effect.
