I’ve also seen a misalignment where the type slug is rubbing against the type guide as it imprints the letter. You should see this by slowly moving the type bar up to the print position, the slug should be centered in the type guide, not rubbing on either side.

Check the type bar linkage as it moves in the slot of the segment. The sides of the type bar that touch the slot as it rotates could be hanging up with gunk. I use mascara brushes in the slot.

How is the alignment of the typed letter? Perhaps the type bar is slightly bent at the pivot point in the segment. Careful “reforming” to one side or the other might help.

Try moving the type bar by hand for its full stroke, very slowly, you should be able to feel it hanging up.

Naphtha works well but quickly evaporates. White lamp oil, the kind used in smokeless oil lamps (NOT tiki torches) is very similar and much less expensive than buying little containers of lighter fluid.

For cleaning in the segment slots, genuine pipe cleaners are good, as are disposable mascara brushes, purchased at beauty supply shops. These have a flexible tip that you can bend to shape.

I like to alternate between naphtha and isopropyl alcohol, working the type bar back and forth for it's fullest extent. Any metal-to-metal surface needs to be worked alternately with naphtha and IPA to get the grunge out.

I'm not intimately familiar with Ericas, but the type bar linkages all operate the universal bar underneath, that does common functions like advance the ribbon spool, raise the vibrator and trip the escapement to advance the carriage. Having the vibrator hang up, and the keys hard to press, suggests the vibrator itself, or its linkage, are the problem.

On most all other machines I'm familiar with, the vibrator should easily fall back down under its own weight. I'd suggest thoroughly degreasing the tracks that the vibrator rides up and down on with alcohol and naphtha (zippo lighter fluid or smokeless lamp oil). Use cotton buds, be sure to clean out all the old gunk from ink buildup and hardened lubricants. Also check the linkage that  raises the vibrator that it is free to be moved by the universal bar.

There is a chance that sometime in the past the vibrator got bent when someone was trying to change the ribbon.

As an example of model variation, my SF has the raised Olympia badge on both the left and right sides of the ribbon cover. You can imagine they could have easily replaced one of the two with Socialite, for example.

Harbor Freight Tools here in the States sells a small aerosol can that can be refilled from a compressor via schreader valve. It's only limitation is the max pressure is fixed and doesn't supply the pressure that a fresh disposable can of air provides.

The Lettera 22 should also have the special shoulder nuts installed for securing the spools to their shafts.

The + and - under the ribbon cover should be the touch adjustment. A lever nearby will offer a variable hardness to the feel of the keys - that is, if the machine has been properly degreaser. Often on many old machines the touch adjustment makes little difference.

The other key looks like the margin release, which you press to permit typing past the margin stop. On some machines it also serves to dejam the keys when you accidentally press two at once.

I've seen this happen on American style keyboards, which I attribute to A being frequently used (3rd most frequent letter in English), but is typed using the weakest finger of one's less dominant hand (assuming you are right handed). It's the confluence of these factors - frequently used letter typed using weakest finger of weakest hand - that can exacerbate escapement issues already present in the machine.

Ideally, those machines should be serviced; but in the interim try index finger typing with your left hand while touch typing with the right, which I find helps a lot.

I was thinking doing this to one of those boxy Smith-Corona cases would be better than on the typewriter itself.  But well done anyway!
