What to do if Casio PR-420A has poor printing, the motor doesn't stop, or digits are missing?

If you're experiencing poor printing, a motor that won't stop, or missing digits on your Casio Calculator, the timing signal might be bad. Check the detector of the printer block and the timing signal. Also, the printer magnet might be defective.
