Standard Paper Sizes and their Uses
In typewriting work, errors and mistakes must be corrected. To produce accurate documents all errors must be neatly corrected. When errors are found in a typed work, the following materials can be used to erase the error:
If the typewriter eraser is being used, first move the carriage so that the mistake is outside the type basket. Then turn up the paper so that the error, or mistake rests on the erasing table of the carriage. Erase gently to avoid making a hole in the paper. Return the paper to the typing line and type the correct letter(s) or word(s) .��
If the rubber eraser is being used, lightly rub the mistake up and down until the mistake is cleared. Return the paper to the typing line and type the correct letter(s) or word(s).
Where the correcting fluid is being used, rub the tin liquid across the mistake, and allow to dry. After making the correction, return the roller to the line of typing and type in the correction. Tip-Ex is an example of correction liquid.�
This is mechanical paper treated with fluid and powder. To use it, place the coated part of the paper on the affected characters. Then type correction on the correction paper and remove the paper from the machine.��
