***These steps apply to both the "B (3340/3442)" and "MS (331/441)" variants of this printer. The ONLY DIFFERENCE with the MS version is that the firmware is tweaked to use a different toner and will take a larger black toner compared to the "B" variant. It is a binning variation where they use the same parts between the two units, but differentiate them with firnware. You can buy one or the other and get the same unit but cannot interchange toner.***
***They are so close, they even use the same 40k page drum unit (which is honestly a far cry better, back before these the "entry level drum" was ~20-30k pages, not much better than the common 12k page Brother drum back then)!***

With that out of the way, here's the issue: The sensor inside the toner compartment is probably broken and needs to be replaced, or there is paper under the cover, which can be cleared by taking the two screws marked in red ***(use a stubby screwdriver unless you want to remove the side panels and top cover -- there is no working room without removing the top panel on this model)***. Use a small object like a toothpick to see if the sensor moves freely. If it does not, the sensor is broken and needs to be replaced, as it is creating a false jam by being stuck in the closed position too long.

The sensor is towards the bottom of the printer and is a bit tricky to replace AND requires significant disassembly :-(. I have attached photos to show how much of the printer is inaccessible from the bottom with this particular unit:
