GrumpyTim | Casiowriter CW-20 - Electric Typewriter Keyboard Repair @GrumpyTim | Uploaded 1 year ago | Updated 1 hour ago
The Casiowriter CW-20 was one of many electric typewriters (or more accurately thermal typewriters), that came out in the 1980s, just before computers and word processors became the normal machine for letter writing. Early electric typewriters were essentially manual typewriters with an electric motor to fire the hammers into the platen. Then there were things like the amazing IBM golf ball typewriter and daisy wheel typewriters, and finally, along came the thermal typewriters from companies like Canon, Brother, Casio and so on.
My CW-20 didn't work when I first got it - initially the LCD screen displayed "RAM Dead: Reset" and after a little searching, I found out that this can happen after the batteries have been changed. The reset procedure appears to be turning the typewriter on whilst holding the CMD and Margin Release keys. Once that error was cleared, most of the keyboard didn't work - this turned out to be a damaged ribbon cable on the keyboard membrane, along with dirty key contacts on the membrane itself. Once all that was sorted the typewriter worked perfectly (I did take it apart again and now the Tab Set key and the letter "S" work as they should do).
