How To Underline On Typewriter: Professional Techniques For Manual And Electric Machines
Underlining on a typewriter requires either backspacing to manually strike the underscore character or utilizing the dedicated underline key found on late-model electric machines. Achieving professional results depends on consistent carriage tension and the precise alignment of the underscore symbol relative to the baseline of your printed text.
Mechanical Prerequisites and Machine Capabilities
Before attempting to add emphasis to your documents, you must verify the specific capabilities of your typing machine. Not all typewriters are equipped with a dedicated underline key, and even those that are may require specific mechanical maintenance to ensure the line appears straight and solid.
- Essential Equipment: A typewriter with a clean, fully-inked ribbon to ensure the underscore does not appear patchy or faded.
- Prerequisite Knowledge: Understanding your typewriter’s carriage release lever and the backspace mechanism is critical. You must be able to move the carriage with surgical precision to ensure the underscore aligns perfectly beneath your chosen word.
- Budgetary Considerations: While the cost is near zero for standard typing, high-quality archival ribbons are recommended to prevent bleeding or smudging during the underlining process.
- Time Estimate: Expect to add approximately 10 to 20 seconds per underlined word depending on your proficiency with the carriage return and backspace keys.
Executing the Underline Process: The Manual and Electric Workflow
Step 1: Complete the Primary Typing Sequence
Finish typing the word or phrase that requires emphasis. Do not press the carriage return or advance the line until the underlining is complete. If you are using a manual machine, ensure the carriage is locked in place. If you are using an electric machine, you may have more mechanical assistance, but the placement remains the operator's responsibility.
Step 2: The Backspace Maneuver
Once the text is typed, return the carriage to the position immediately preceding the first letter of the word you intend to underline. On most standard American-keyboard typewriters, the backspace key moves the carriage exactly one character space to the left. If the word is five letters long, press the backspace key five times.
Pro-Tip: If your typewriter has a very stiff backspace mechanism, press the key firmly and slowly. Jerky movements can cause the carriage to skip, leading to misalignment where the underline appears either too high or disconnected from the letters above.
Step 3: Aligning the Underscore Key
Once the carriage is positioned correctly, look for the underscore character on your keyboard. This is typically located on the same key as the hyphen or the plus sign, often requiring the Shift key to activate. Position your finger to strike the key with consistent force.
Step 4: Applying the Line
Press the underscore key while ensuring the carriage does not jump or shudder. If your typewriter features a dedicated underline key that automatically advances the carriage, hold the key down until the entire word is underscored. If you are using a standard underscore character, you must manually press the underscore key, then the space bar or the carriage advance mechanism, then the underscore key again for each letter.
Warning: Avoid striking the keys with excessive force. Typewriters have a mechanical limit; hitting the underscore key too hard can cause the metal typebar to strike the platen unevenly, resulting in an underline that looks thick at the ends and faint in the middle.

Technical Specifications and Comparative Methods
The following table outlines the distinct methods for underlining based on typewriter category, noting the mechanical requirements for each.
| Method | Machine Type | Mechanism | Precision Level |
|---|---|---|---|
| Manual Backspacing | Vintage Manual | Carriage return/Backspace | High (Operator dependent) |
| Dedicated Underline Key | Late Electric | Solenoid/Motorized strike | Very High |
| Redundancy Method | Portable | Re-typing underscore | Moderate |
| Platen Adjustment | Professional Office | Ratchet override | Low |
Managing Common Mechanical Failures and Alignment Issues
Even experienced typists encounter issues with the aesthetic quality of their underlines. Addressing these issues immediately ensures the document retains a professional appearance.
- Root Cause: The underscore appears staggered or jagged.
- Actionable Fix: Ensure your carriage rails are free of debris. If the carriage is skipping, check the drawband tension; if it is loose, the carriage may not seat properly in the escapement teeth, causing uneven character placement.
- Root Cause: The underscore is faint or incomplete.
- Actionable Fix: Your typewriter ribbon may be drying out at the bottom edge. Try adjusting the ribbon selector to a different color setting (e.g., from red to black or vice versa) to utilize a fresher part of the ink fabric, or re-ink the ribbon if you are using an archival-grade spool.
- Root Cause: The underline is too close to the text, cutting into the descenders of letters like "g," "j," or "y."
- Actionable Fix: This is a design limitation of standard typewriter fonts. To mitigate this, use the platen release knob to rotate the platen a fraction of a millimeter forward before striking the underscore. This creates a slightly larger visual gap between the letter and the line.
Frequently Asked Questions
Can I underline while typing the word?
No, most standard typewriters require the text to be typed first. You must finish the word, backspace, and then apply the underline to ensure the placement is mathematically aligned with the letters above.
Does the underline key automatically space the carriage?
On most manual and early electric typewriters, the underscore key is just a character key and does not advance the carriage. On high-end electric models from the 1960s and 70s, some feature a dedicated "underline" function that advances the carriage while striking the line.
Why does my underline look like a series of dashes?
If you are using a standard underscore key, the underline will appear as a series of connected or disconnected dashes based on the font kerning. To achieve a solid line, ensure the typebar is striking the paper with sufficient pressure to create a seamless impression, or consider using a single, long dash if your machine allows.
Should I underline headings with a typewriter?
Underlining headings is a common practice in typewritten manuscripts. However, because you cannot increase font size, many typists prefer to type headings in all capital letters instead of underlining them to avoid cluttering the visual field.
Maintain Your Machine for Better Results
Regular maintenance of your typewriter, particularly cleaning the typebars with an archival-safe brush and solvent, ensures that your underlines remain crisp and professional. Master the mechanics of your machine today to elevate your typed correspondence.
