1. Empty all beans out of the hopper, and vacuum the remaining beans out the top of the hopper/throat (NOT the chute). Before doing this, the grinder should have been used with some beans in the hopper, not single dosed.
2. Run/pulse the grinder with nothing in the hopper/throat.
3. Sweep chute with a toothpick and pulse again to make sure the chute and burr chamber is clear.
Catch and weigh anything that comes out the funnel.
The Robur-E holds close to 2 doubles worth of stale coffee from the above procedure. I'd bet the Major-E is WAY less.
If you get the chance, I've not found anyone else with one.

I tried this with my dosered Major a few minutes ago with the only difference being that I had swept the front of the chute out for the previous shot. I placed a small tared container under/in front of the chute so it would catch any grounds, pulsed several times & swept the chute. The total weight of the captured grounds was .7g. This jives with what I've seen when I remove the upper burr carrier for cleaning. There are very few grounds left in the burr chamber. I had guessed that it might amount to a gram or so & I wasn't far off. This is much less then I used to see left behind in my SJs.
I removed the upper burr carrier & shot this photo (not great) that shows what is left behind after the pulsing.

Unlike the SJ the dosered Major will leave only a small amount in the chute which is easily swept into the doser. Since I also have a Major with the funnel conversion I can tell you that if you use the wire grid over the chute you will want to keep a small vacuum nearby to clear it after an idle period between shots. I've tried it with & without the grid & finally left it off permanently. My biggest complaint with the funnel kit is static, not clumping. I much prefer the doser with a few mods for this reason.
I haven't done any back to back taste tests as my SJs went into storage when I bought the Majors but I will say that I do prefer using the Majors over the SJs.
