Reply To: Page Change Indicator
If you mean, by page change indicator, the line of dots 36 across the page, such an indicator is not required in either situation you mentioned in your post. The page number would advance in the upper right corner for each. No page change indicators are inserted on line 25 or line 1 of a braille page. BF 1.11.4 "Begin the new print page on the next braille page when there is not enough room for the page change indicator and one line of text."
