Why does an All-in-one Printer have a scanning glass, when it can scan with an Automatic Document Feeder?

Isn't the scanning glass in Fig. 1 redundant? Fig. 2 also features the HP OfficeJet 8710.

No. The scanning glass is useful where documents dont fit into the sheet feeder - like books, A3 docs, multiple text receipts, fragile documents, small things like photos.



Also if you want a high res scan of a small area, its a lot easier to do it on the glass.

  • Also: ADFs are notoriously unreliable unless the paper is in near-perfect condition. Even if the document "fits", it may be impossible to scan it with an ADF.
