Convert scanned images to PNG before further processing
This might need unchecking if scanning images.
Note that the Scan dialog opens too small to show all the settings - enlarge it before doing anything else.
#Pages: select All if using ADF - it should stop scanning when feed tray is empty.
Source document: select Single sided or Double sided. Select Facing or Reverse if doing double sided - although this seems to be handled automatically when doing double sided.
Save: I'm not sure what this saves - probably just the page options.
Edit: this opens a dialog that allows deletion of Backend: Scan source and Frontend: num_pages. I don't know what this means.
Scan mode: select Lineart (for line diagrams or text), Grey or Color.
Scan resolution: default of 100dpi is too low for most purposes. 300dpi is better for text. 400dpi is recommended for OCR.
Scan source: select Flatpad or ADF for Epson printer.
Select Paper Size as Manual, A4 or Edit (to enter dimensions). I think "Manual" might mean "Automatic", but I'm not sure.
