Abstract

In even a basic electronic typewriter, the complexity makes servicing these machines difficult. However, this same electronics can be made to diagnose its own problem. Now, whenever a display is available on the machine, an error code may be displayed to the operator at little extra cost, when the problem is located by the machine. With this error code, the engineer can bring the correct parts to repair the typewriter.

In even a basic electronic typewriter, the complexity makes servicing these machines difficult. However, this same electronics can be made to diagnose its own problem. Now, whenever a display is available on the machine, an error code may be displayed to the operator at little extra cost, when the problem is located by the machine. With this error code, the engineer can bring the correct parts to repair the typewriter.

The principal information the operator needs to see is the present pitch, index value, impression level and status of text processing function involved. Other information can also be made available, as needed. For instance, warning information like end-of-ribbon, etc., may be brought to the attention of the operator by flashing a displayed message.

Any available alphanumerical display could be used, such as a seven segment display, as represented in the figure. Such a display is designed to have minimum cost and low system support requirements.
