To eliminate all the font changes when scanning a legal document, ensure that the scanning software is set to recognize text as plain text or use OCR (Optical Character Recognition) settings that maintain uniform formatting. Alternatively, convert the scanned document to a text file and manually adjust the font settings to your preference.

To avoid font size changes when copying and pasting from a PDF to WordPerfect, try the following steps: 1. **Use a PDF to Word Converter:** Instead of copying and pasting, use a PDF to Word converter tool to convert the entire document into a Word format, which can then be opened in WordPerfect. 2. **Paste Special:** When pasting into WordPerfect, use the 'Paste Special' option and select 'Unformatted Text' to avoid carrying over any formatting from the PDF. 3. **Check PDF Settings:** If using Foxit, check the settings for text recognition and conversion to ensure they are optimized for maintaining consistent formatting. 4. **Update Software:** Ensure both Foxit and WordPerfect are updated to the latest versions, as updates may fix compatibility issues. 5. **Manual Adjustment:** After pasting, manually adjust the font size and style in WordPerfect to ensure consistency throughout the document.
