Some Keys Feel Squishy on Programming Wing Face Panel

Symptoms

Some of the keys feel squishy or squidgy when pressed, not clicky like the others.  They can also feel very hard to press down.

Explanation of Issue

Eos family face panels use elastomer light blockers around the switches to prevent light bleed to other keys. These rubber light blockers can sometimes get loose in shipping or if the console is stored with the rear of the console facing down.

If the rubber pieces below the key caps did get knocked loose in shipping, repeatedly tapping that key while the console is sitting on a flat surface with the keyboard facing up can usually force the light blocker back in place.

If repeatedly tapping that key does not resolve the issue, the light blocker may be in the incorrect orientation.

Solution

  1. Repeatedly tap the key to attempt to force the light blocker back in place.
  2. If that doesn't work, use a keycap puller to remove the keycap from the problem key.
    1. If you are in need of a keycap puller, Contact ETC Technical Services to request ETC PN I503 and mention this article.
  3. Inspect the elastomer light blocker. There should be two bump-outs on either side of the blocker.
  4. These bumps should be on the left and right of the keycap, not the top and bottom.
  5. Re-orient the light blocker if necessary.
