Peeling Back the Layers

An Olivetti Lexicon 80E gives up its secrets slowly.

When I bought it I knew the draw band had been disconnected. The band did not look broken or frayed and I assumed that it had just come loose from the pulley. Tracing the path of the band past a few rollers and guides I was able to find where it connected, but was thwarted by the case. From what I could see there were two screws holding on the whole of the body.


 I loosened the screws but the body was pinned by the carriage. I took a gamble and figures that the carriage on this machine was removable. It seemed a likely possibility. What repairman would want to disassemble and entire carriage and sub-assembly just to get to a ribbon vibrator? I looked around and settled on two screws. After removing them, the carriage, escapement, and other components lifted out easily. The whole operation is very reminiscent of what you would see on the Olympia SG-1.


After that I was able to remove the body panel (there were two additional screws) and gain access to the draw band pulley. The real mystery is how the darn thing is connected. I intend to work on the pulley today and with any luck I might be able to fire it up. I haven't even plugged it in because I really want to get in there and look around. Also, there is a very large capacitor that gives me the heebie-jeebies. I would not want to meet with it fully energized.


I have yet found a serial number on the body, but I did find this hand-scrawled number on the carriage. 2876? What could it mean? Perhaps 2876 pounds; the weight of this typewriter.

  4. Wow it seems Olivetti used a capacitor start motor or maybe capacitor run or both motor on that machine. Interesting. It looks like a very interesting machine to work on.
