DPI stands for “dots per square inch” and is one way that image reproduction resolution is measured. Finding the resolution capabilities of your scanner is as simple as looking for the initials DPI. First, check the resolution of your scanner. Sometimes Simple Is BetterĮven if you know next to nothing about imaging technology, you can still evaluate flatbed scanners along a few simple comparison points.

They connect to your computer via USB port, and some of them are even equipped with wireless capabilities that can help them network throughout a busy ofice. Today’s flatbed scanners are built for convenience and, often, portability. Some scanners can automatically convert color documents and photos to black-and-white. But, if you are planning to scan a lot of photographs, higher resolution is the way to go. Odds are, you will spend slightly more for a higher resolution. The resolution quality you get with a flatbed scanner will vary depending on your model. They are perfect for scanning and saving sentimental photographs or documents that might tear easily, as well as books you want to preserve. Drum scanners require you to feed your documents through rollers that can prove damaging if you are trying to scan anything remotely fragile.įlatbed scanners are the most popular type of image scanners because they are easy to use and are compatible with most computer operating systems. This makes a flatbed scanner different from a drum scanner in that it uses light–rather than photo-multiplier tubes–to operate. The original flatbed scanners required three passes to completely scan an image, but newer scanners have multiple-CCD arrays, which allow them to quickly scan images in one quick pass. They scans line by line and pixel by pixel to carefully translate your media into a usable digital file. Scanners use a combination of light and mirrors to bounce reflection of your document or photograph toward one or more sensors. Once you've digitized the material, you can edit it however you please. A flatbed scanner uses optics to convert a physical form into digital media.

You'll also notice we upgraded the previous Canon Lide offering to the Canon Lide 400, which is almost identical to the 300, but has a little bit more speed and offers USB Type-C connectivity.Ī flatbed scanner is perfect for anyone who wants to preserve and back up printed photographs, or for offices that need to save or edit important documents. The HP Scanjet Enterprise Flow N9120, for example, can plow through up to 20,000 pages per day in its ADF, and then turn right around and render some of the finest archival work for pictures and paintings on the market. We also found that dedicated flatbeds often offered higher duty cycles than the average all-in-one printer, which is especially important for business use. The main reasons for this are that we already have a comprehensive list covering all-in-ones and that we feel anyone searching specifically for a flatbed is likely a photographer, artist, or archivist who wouldn't be able to do much with the inferior resolving power of the scanners often built into printers, especially when it comes to rendering colors accurately. Looking over the available flatbeds on the market, we made the executive decision not to include any all-in-one printers on this iteration of the list as we have in years past. Additionally, we included an HP model at a more wallet-friendly price point that still offers solid performance, particularly with document scans. We opted to remove the HP Digital Sender Flow 8500, as it felt a bit redundant with the HP Scanjet Enterprise Flow N9120, which offers superior overall performance in a comparable price range. Epson offers a range of price points, represented here, without compromising its vetted quality and performance, though for whatever reason, only their most expensive consumer model was previously included in our ranking. While our list was previously dominated by more text document-friendly scanners, we added a few models from what is widely considered the foremost name in photo scanning and printing: the Epson Perfection V850 Pro, Epson Perfection V600 and Epson Perfection V39.
