Unlike modern computers with dedicated "delete" keys, traditional manual typewriters do not have a digital deletion function. Correcting errors typically involves manual methods to obscure or remove ink from the page. However, some advanced electronic typewriters did incorporate specific features for erasing text, akin to a modern "delete" function.
Traditional Methods for Correcting Errors on Manual Typewriters
On most manual and early electric typewriters, mistakes were corrected by physically altering the typed page. These methods required careful execution to achieve a clean correction.
-
1. Correction Fluid (e.g., Wite-Out)
- Description: A white, opaque liquid painted directly over the incorrect characters. Brands like Liquid Paper and Wite-Out became synonymous with typewriter corrections.
- Process: A small brush or applicator is used to apply a thin layer of fluid over the error. Once the fluid dries, the correct character(s) can be typed over the white patch.
- Pros: Effective for covering various types of errors, from single letters to entire words.
- Cons: Can be messy, requires drying time, and the corrected area is often visible upon close inspection, especially if the fluid is applied unevenly or too thickly. This method also adds bulk to the paper. Learn more about the history of correction fluid.

2. Correction Paper/Tabs
- Description: Small pieces of paper or tabs coated with white, opaque material on one side.
- Process: The correction tab is placed over the error, and the incorrect character is retyped. This action transfers the white material from the tab onto the paper, covering the mistake. Then, the correct character can be typed.
- Pros: Generally neater than correction fluid and dries instantly. Ideal for correcting single characters or small errors.
- Cons: Can be difficult to align precisely, especially for multiple character corrections.

3. Correction Ribbons
- Description: Some electric typewriters featured special correction ribbons, often called "lift-off" or "cover-up" ribbons.
- Process: The user would switch the typewriter's ribbon setting from "type" to "correct," then retype the erroneous character(s). A lift-off ribbon would adhere to and literally "lift" the ink off the page, while a cover-up ribbon would lay down a white, opaque layer over the mistake. After correction, the ribbon would be switched back to "type" to input the correct text.
- Pros: Offers a very clean and often seamless correction, especially with lift-off ribbons.
- Cons: Required specific typewriter models and compatible ribbons, which could be more expensive or harder to find.
Electronic Erase Functionality on Advanced Typewriters
With the advent of electronic typewriters in the late 20th century, some models introduced features that provided a more automated "delete" or erase capability, similar to early word processors. These functions typically used specialized mechanisms or ribbons to remove typed characters.
Utilizing the 'W OUT' Feature for Word Erasing
On certain electronic typewriters, a dedicated function, often labeled "W OUT" (Word Out) or similar, allowed for electronic erasure:
- Erasing a Full Word: To completely remove an unintended word, the user would press the 'W OUT' function. This activated the typewriter's correction mechanism, which would erase the entire word character by character, usually by lifting the ink off the page or covering it with an opaque layer.
- Carrier Repositioning: A key benefit of this function was its automation. After the word was erased, the typewriter's carrier (the part that moves the paper across the typing line) automatically repositioned itself to the exact spot where the first character of the now-erased word had been. This made it incredibly convenient to immediately retype the correct word without manual alignment.
- Partial Word Erase: The 'W OUT' function also offered precision for mid-word corrections. If the carrier was positioned in the middle of a word, activating 'W OUT' would specifically erase only the letters from that current position backwards to the beginning of the word. Any letters positioned after the carrier's initial location in the word would remain untouched.
This electronic erase functionality significantly streamlined the correction process compared to manual methods, offering a faster and often cleaner way to rectify errors directly on the machine.
Best Practices for Typewriter Corrections
Regardless of the method, effective corrections on a typewriter required skill and attention:
- Proofread Constantly: The best correction is to avoid errors in the first place. Typewriters made real-time proofreading essential.
- Choose Wisely: Select the correction method most appropriate for the type and severity of the error.
- Practice Precision: Manual correction tools require a steady hand and accurate alignment.
