As Document Management experts, we often get questions about picking out scanners.

And those questions lead to more questions, especially about all the different terms.

What does ADF, DPI and PPM stand for and why do they matter?

What’s the difference between SIMPLEX and DUPLEX?

In this video, Bennett explains what you need to know when making a decision on scanners.


If you’d prefer to read rather than watch, you can take a look through the full transcript below:

If you’re new to scanning and imaging, some of the terminology may sound confusing, such as ADF, DPI, DUPLEX, SIMPLEX, and PPM. But don’t worry, in today's episode, we’re going to explain what these terms mean.

ADF – Auto Document Feeder. This refers to the tray that holds the pile of paper you want to scan. Instead of loading a scanner one page at a time (who wants to do that?) the ADF capacity indicates how many pieces of paper you can load into the scanner’s feeding tray all at once. So why would you want this? Well, when your drivers drop off all the trip documents, you could load everything together into your scanner in one shot and get them scanned.

DPI – Dots Per Inch. DPI is a measure of resolution used when converting paper to electronic images through your scanner. For printed text or images, the more dots per inch, the higher the resolution and image clarity. Some common examples are 600 x 600 dpi or 1200 x 1200 dpi.

Higher dpi numbers correspond to smaller dots when printing an image. In general, devices with higher dpi can produce finer lines and more detailed output. However, please keep in mind that the higher the DPI, the larger the electronic image file size will be and could impact the amount of hard disk space your imaging server will require to store the images.

SIMPLEX – Simplex scanning is a feature that allows the automatic scanning of a sheet of paper on one side only.

DUPLEX - Duplex scanning is a feature that allows the automatic scanning of a sheet of paper on both sides. Devices without this capability can only scan a single side of a sheet of paper at a time.

PPM - Pages Per Minute. PPM is used to measure the scanning speed of the scanner under a certain configuration. Most scanners include a PPM rating for both black and color scanned images. These speed measurements are typically listed in the printer's technical specifications.

While a higher pages per minute rating does indicate a faster scanning speed, this measurement can be misleading. This is because manufacturers measure the maximum PPM in the fastest scanning mode, which provides for the lowest image quality.

You should now be familiar with the terms used to describe scanning speeds, capacities, image quality and more, so you can find the right scanner to fit your needs. Thanks for watching!
