I'll be the first to admit that if you have a decent smartphone, you can probably get along just fine without one. And that's a good spot to resume our discussion from the top of the page: do you even need a scanner anymore? With this scanner, you can digitize anything from a business card to a receipt to a legal-size sheet of paper. The scanner connects to computers, phones and tablets over Wi-Fi. Of course, when you're ready to actually view, share and organize your documents, you can skip the usual USB connection. So there's no computer required to operate the scanner or house your scans. In practice, you'll want a much higher PPM/IPM if you're expecting to scan frequently, preferably a scanner that also has an ADF-an automatic document feeder so you don't have to feed the machine manually.The Doxie Go is a portable, battery-powered sheetfed scanner that can store up to 450 documents internally, and more if you add an SD card. For example, if a scanner is rated for 16 PPM, then it can scan 16 pages in a single minute.
PPM and IPM both determine the speed at which the machine scans PPM is Pages Per Minute, whereas IPM is Images Per Minute. One of the most important aspects of a scanner, and what you should be conscious of, is PPM and IPM.
This is typically reserved for sheetfed scanners only if you pick a flatbed scanner, it likely won't have this feature. It's just a fancy way of saying the machine will scan both sides in a single pass through, saving you the hassle of flipping the page over to scan the other side of documents.
You'll find that many scanners offer a feature called "duplex scanning." A DPI resolution of 1200 and higher is acceptable for scanning photos. As for photos, it depends on the size of the image the larger the photo, the higher the DPI should be. In the context of a scanner (and printers), DPI means "Dots Per Inch." In other words: the higher the DPI, the better the quality of the scan and or print.įor simple operations like scanning documents, you'll do just fine with a DPI resolution of 300.
