I asked myself the same question, or rather I addressed it to digitec. Answer from Digitec: According to the manufacturer's page, the 8022 can only print duplex, which is the case with all 8000 printers. [Assume this should mean that this is the case with all 8000 series printers]. Digitec should definitely change the specifications here. You can, however, scan double-sided pages by not scanning them via the ADF but via the flatbed scanner and simply flip the page in between. This should work.
