In ebook-sized builds, fancyhdr emits a lot of warning messages complaining tight headheight (once per output page): Package fancyhdr Warning: \headheight is too small (10.84006pt): (fancyhdr) Make it at least 12.0pt, for example: (fancyhdr) \setlength{\headheight}{12.0pt}. ... fancyhdr can be satisfied by moving 0.0165in from headsep to headheight. This change has very little effects in the header area (page count position).
