From the HP OfficeJet Pro 8620 I promised to unite Duplex Scan and office printing in a single compact unit, thus saving office space. The low price per se has not put me off because my previous devices are from a completely different price generation. I expected a certain degree of 'lightweight', but not with functional regression. Just that I have experienced, however.
Compact I'd HP OfficeJet Pro 8620 does not call, and the (target only-black and white) print image falls short of my ancient (Can-only-black and white) laser printer significantly, despite the latest HP Ink high technology, if I correctly have understood.
But what are really disillusioned me the limitations of the ADF scanner. They were not clear to me from the machine specifications and were also in any of the previous reviews summarized so that I would have understood it.
First: are the optically possible 1200dpi in ADF mode only 300 available. That's enough for Office applications completely, but it is still important to know.
Critically, however: Duplex Scan works with this equipment in two passes, ie only one side is scanned and the template almost completely ejected, then it is drawn in again and turned back the scanned - ie as in duplex printing. The device comes like this with a single scan sensor. This construction may be antiquated, but in itself not a problem, and also intake, wrinkle and congestion problems or ignored backs, I have not observed in the first hours of operation. The HP OfficeJet Pro 8620 but bucks the turning mechanism when it is fed with an unknown and in particular to short format. DIN A5 eg therefore can not be duplex scanned! Jededenfalls not vertically.
But even in landscape mode. And that shows in my opinion, as A4 portrait can be duplex scanned quite possible that this limitation is not due to a mechanical impossibility, but the manufacturer of absentmindedness. That A5 not even found in the TWAIN driver in the list of known paper sizes, supports this impression. (In the WIA driver A5 appears indeed what in itself is funny, but does not help: it does not remain not work.)
For a small duplex scanner, as in my case, the Plustek SmartOffice PL1530 (duplex scanning with two sensors in one pass), this device is therefore hardly a way forward. If you expect that you will be disappointed, as I do.
(The shown in the photo "may I could have, but want I do not want" message there's certainly also in German.)
