Machine story: | At the moment of arrival the machine was working with a few errors. Cleaning the machine and fixing a spring in the carriage solved the "first digit" error. A number of key tops were hanging. Dismantle the machine and cleaned more thoroughly, the machine was fully functional again. Replacing a handle, with a spare one from a defect machine, completes the machine again. |
