ADFs (Automatic Document Feeder) are commonly found in printers, fax machines, photocopiers, and scanners that have multifunction capabilities. You can also call them multi-scanners. They allow many pages to scan one by one automatically without any manual interference. Depending on how many pages are involved, it can feed them into a printer. There are copiers that allow scanning on the flatbed or platen as well as in the scanner.

The majority of faxes are equipped with an automatic document feeder (ADF) and allow remote sending of multipage faxes. Multi-page documents are scanned and printed with ADFs that are widely integrated into fax machines.

How does an ADF Works?
ADF is designed to scan multiple pages at once without any hurdle or manual functioning. You just have to place the page on the intake tray on an ADF machine either printer, fax, or photocopier.
Now you have to give the machine scan options. Do not forget to connect your machine with your computer or laptop to display the scan result if you want. You can also print your scan files directly.
There are multiple rulers that slide the paper into the scanner automatically. The scanner reads the paper print and gives commands of print or copy.
Automatic Document Feeder – RADF vs DADF
Document feeders that reverse automatically are called RADFs. One scanner is built into this type of processor. On the glass side of the copier, the scanner is embedded. Original two-sided documents will automatically reverse. A scan of one side of the page is performed before it is automatically flipped around and scanned on the other.
Dual Scan Document Feeders – sometimes called single-pass scanners or DSDFs – can be used as an alternative to the RADF scanner. A growing number of large manufacturers are now using DSDF scanners like Canon, Konica Minolta, Kyocera, Lexmark, Samsung, and Sharp.
Two scanners are integrated into the structure of machines that use Dual Scan Document Feeders. The DSDF machines, on the other hand, are able to scan or copy both sides of a double-sided page at once.

ADF Printer having Simplex Function
ADF printers work with different feeding processes. The ADF simplex version is well known and used with numerous devices. Each document page is drawn into the device individually and then fed onto a rotating roller that reaches across it and lifts it up, scanning it along its photoelectric surface all at once (this is similar to how a scanner works).
Using the simplex process, the ADF printer only scans the front or backside of a sheet, the other side is just put down on another tray in the machine which can be accessed by opening its lid. Devices with simplex functions are mainly used in households and cost less than ADF scanners with DADF or RADF.
ADF Printers with Multifunction
An ADF is commonly found in printers that have multifunction capabilities, fax machines, photocopiers, and scanners. An automated document feeder (ADF) is a stacker which reveals pages of paper sequentially to the printer or scanner to be printed or scanned.
An Automatic Document Feeder (ADF) is a multifunctional printer that has the ability to scan, copy and fax documents. There are two types of ADF printers: ADF-only, and ADF/printer hybrids. If you need to scan, copy and fax documents, the ADF-only printer will be the best option for you.
If you want to scan, copy and fax documents, and also need to print documents, the hybrid printer will be the best choice. ADF printers are commonly found in printers that have multifunction capabilities, fax machines, photocopiers, and scanners.
What are the benefits of ADF?
ADF can be beneficial in many fields and will make your work easy and efficient.
- In educational institutes, it could be time-saving. Most of the work or notifications in institutes needs to be copied. ADF may helpful in this regard.
- You can use multiple pages at the same time to make copies. You don’t have to put them manually one by one.
- Some latest ADF-affiliated machines can store the scanning results for multiple printing. Thus you can print without feeding the original document again and again.
- Time-saving quickly makes scanned copies of any documents single-sided or two-sided.
- The advanced AI technology in the new printing machines may enable OCR features in the latest ADF machines.

Precautions for Using Your ADF
- Paper that is torn, frayed, or spiraled from a binder should not be used. Always verify that all edges are straight.
- You shouldn’t use photos since they can easily be damaged. You can scan or copy photos using your regular scanner or copier.
- It is very important to make sure that your paper fits snugly against the paper width guides and that it doesn’t bend while printing.
- Ensure that the sheets of paper do not contain any staples or clips.
- Do not overload the feeder with too much paper. We suggest that you put no more than 20 sheets in each printer, depending on the manufacturer. You can use more than 20 in the photocopier.
