Well, one out of two is better than goose eggs... glad I could provide
some insight into it, although I could not recall exactly where the
microswitch was on that model.

Problem solved. After inspecting and realizing where the microswitch
actually was (it's in the front of the cartridge at the top) I saw that it
was actually flipped upwards. Pushing it back into position enacted the off
light position and the printer is happy again pushing ink. Those 880's are
about the most precious classic ink jets around. Cause for celebration.
