We had a missing part that, after contacting the seller they acted very swiftly to replace this. Then followed up to ensure it had arrived safely.The product is excellent and just as described. Would thoroughly recommend.

Spijitig dat de vertikale arm niet kan verlengd worden. Is nodig als het boek wat groot is. Oplossing is er de scanner op een verhoogje zetten.

I was searching for something to replace my old 11x17 flatbed scanner that is no longer supported. I had my doubts when ordering this product, but I was pleasantly surprised. You have to be very careful about making sure you have good, even lighting, and you have to be careful about aligning the sheets consistently, but the results are quite acceptable. This would be a good product for someone trying to scan large maps.I am going to buy a plexiglass sheet to hold the papers flat, but that's the only change I'd make.

Honestly, I expected this scanner to be better than it is. Specifically, the tiny light embedded in the overhead arm is laughable. It does not have enough light for a great image, and it is horrible if you are scanning any glossy surface. I did purchase two lights to augment the existing scanner light. The software works ok. The book flattening works if the page is mainly flat, to begin with, but not so well with a bowed page. The software is easy to work with and intuitive. I haven't needed to contact any help or support, so I can't comment on that. With all this said, I will continue to use this scanner without expecting flatbed results.

I bought this to scan vintage catalogs and the resolution is really terrible. In addition the arm has a tendency to fall just a bit and it takes things out of square. The most annoying thing is there is no catalog or owner’s manual to tell you how to adjust the brightness saturation.etc. There is a place to do that but no clue how to make it work. There is also several resolution adjustments but with trial and error I am still not getting it. I have thrown away the packaging otherwise I works return this turkey

The quality and ease of using this product was surprising. I frequently scan newspaper articles, and they rarely fit on a flatbed scanner. Thus, I had to use Photoshop to stitch together 2-3 scans of the articles, which took considerable time. This scanner will handle A2 size paper, which is big enough to capture all major newspapers (e.g. Wall Street Journal), is easy and fast to use, and delivers crisp clear optics. It even has its own source of lighting. Excellent buy, and I rarely take the time time to rate products.

I've used various strategies to capture documents and books and I was initially attracted by the 23MP density and large-format scanning. Sadly, the device will not render text with sufficient clarity to take advantage of the sensor size and produce good OCR results; rather, I could get better OCR using my phone or my M4/3 camera. I will be returning this scanner, as it fails at the one job for which I really needed a dedicated device:It's unsuitable for digitizing my personal library of textbooks and literature. If the device's light is off and I use an oblique source of illumination, there is too much noise in the image, not enough contrast. If I increase the ambient lighting or use device's light, I get washout and/or glare that makes texts unreadable. Something in the automatic light sensing and exposure-adjustment either needs refinement or the components are simply not up the task—there is nothing in the software that is available to the user to manually adjust things like focus or exposure.

It seems to work although installing and functioning took some time. Advice from help desk did not help much and the user guide is limited.

Had been searching for a while for a high end, but affordable scanner for my 16 x 20 paintings. I have attached one of the scans. Beautiful. The light on the scanner is best used with no additional lights in the background. You get the best scan.

Je l’ai acheté pour transférer mes livres à l’ordinateur. Il fonctionne mais on a besoin d’expérimenter pour achever un bon résultat.Initialement, j’ai utilisé mes doigts, comme recommandé, mais je trouvais que l’image n’a pas effacé les doigts complètement. Par conséquent, j’ai essayé trouver un autre moyen. J’ai acheté une grande plaque de “verre acrylique” pour placer au-dessus du livre. C’était un succès, mais un peu plus lent. Aussi, j’ai trouvé que les polices coulent en certaines circonstances.C’était aussi nécessaire d’expérimenter avec les lumières. Mais, après du temps, j’ai réussi. Ça dépend sur vos buts.Le scanner est particulièrement utile pour copier de petites choses: cartes de visite; photos. Et, aussi, des documents plats.

Sehr einfach und schnell kann man den Scanner zusammenfalten und in die Tasche packen. Knapp 2kg ist er zum Transport gut geeignet. Wir brauchen den Scanner sowohl im Büro als auch zu Haus. Von daher ist dieser für uns ganz optimal. Büchern zu scannen ist viel einfacher geworden. Mithilfe von der Flat Curve Technologie erkennt der Scanner jede einzelne Seite automatisch und speichert alle Seiten separat. Man spart dabei nur Zeit und Mühe. Die Kamera reagiert sogar sehr schnell, wenn man Seiten umblättert. Der Scanner funktioniert ganz genau wie wir erwartet haben. Wir sind absolut zufrieden.
