Perhaps among all the visitors, many are currently looking for information and explanations regarding these questions. Every multifunction printer, whether in the form of inkjet or laser and which has copy, print, scan, and fax features is certainly also equipped with a device called ADF Scanner or Automatic Document Feeder, which is located at the top of the printer.
You can copy one or two pages of a document quickly by copying it manually on a photocopier. But what if you have a document with tens or even hundreds of pages to copy?
Using the manual photocopy method to copy hundreds of pages of documents can certainly be very time consuming. So to make this job easier, you need a photocopier feature called an automatic document feeder.
Understand more about what the automatic document feeder feature on a photocopy machine is, how it works, and the benefits it offers for your office printing and photocopying activities through the discussion below.
What is an Automatic Document Feeder (ADF)?

Automatic document feeder (ADF) is a feature or part of a photocopier, printer or scanner that is useful for automatically inserting several sheets of documents into the photocopier to then be printed, copied or scanned. Usually, this feature is owned by multifunction photocopiers or all-in-one printers to make the printing and photocopying process more efficient.
In comparison, copying one sheet of document manually on a photocopier can take up to 30 seconds. Meanwhile, with the help of the ADF feature, you can copy 200 sheets of documents in just 1 minute.
How does the Automatic Document Feeder feature work?
Mechanically, the ADF on a photocopier or printer operates by delivering each sheet of document paper using a roller into the photocopy machine.
The more sophisticated the technology of the automatic document feeder feature, the shorter the process required to process documents. One type of ADF, known as a reversing automatic document feeder (RADF), can even help you copy two sides of a document at once by turning your document upside down and then scanning the reverse side.
There is also a type of ADF with dual-scan technology which has two scan sides to copy two sides of the document at once so it can shorten your printing time by up to 70%.
Explanation of ADF in printer specification information
The explanation of the ADF function on the printer is to help the process of scanning, copying, and faxing multiple documents work automatically. With the ADF, you can directly scan or copy many documents without having to bother entering them one by one into the flatbed scanner section of the printer.
So, the existence of the ADF or Automatic Document Feeder and its development is part of the development of scanners or scanners on printers. These devices can be grouped into two based on how the paper is loaded, namely flatbed and ADF scanners.
Flatbed scanners are usually found on multifunction laser printers, which consist of a glass plate and sensors inside the printer. The working system of this type of scanner is that the paper is placed on the scanner glass, then the light and the scanner sensor move along the paper to copy the image.
The way the scanner or image scanner with the ADF type works is that the paper is placed in the tray, which will then be loaded one by one by the mechanical part of the scanner with the help of a pad assy and a roller. Now, when the paper moves over the scanner lamp, the scanner sensor works to copy the image that represents the paper.
Advantages of ADF Type Scanner on Printer
The following are some of the advantages of using an ADF-type scanner on a printer:
- The scanning speed is quite high, it can reach > 10,000 sheets/hour.
- Has the ability to read two sides of the paper at the same time which is called the Duplex Plus Automatic Document Feeder (DADF).
- With the help of an imprinter, a scanner with an ADF system can mark the sheets that have been scanned.
- It is very suitable when combined with the use of software with Digital Mark Reader technology for archiving and document management activities.
If you use an A3 multifunction printer, it's certainly much easier to scan A3, A4, or F4 paper if you use an ADF scanner. However, if you only use an A4 multifunction printer and want to scan F4-sized documents, it will be a little difficult because generally A4 multifunction printers only use flatbed scanners whose scans are limited to a maximum of A4 size paper.
Therefore, the ADF type on the printer is a device that will be very helpful when we want to scan or scan F4 size paper. That is why currently the average A4 multifunction printer that is equipped with ADF can scan F4 or folio paper, which flatbed scanners usually cannot do on A4 multifunction printers.
Although there are also some cases that show the existence of the A4 multifunction printer series that uses the ADF system but cannot scan or scan on F4 paper. Therefore, if you need the ADF feature on a printer, make sure you have this feature before deciding to buy a certain type of printer. Of course, if you really feel you need the ADF feature.
Benefits of Having a Photocopier with ADF Features
Apart from of course being able to increase the efficiency of the printing and photocopying process, having a photocopier with an automatic document feeder feature can provide many benefits for your office operational activities.
For example, the automatic document feeder feature will be very helpful if your office or company is digitizing documents. Digitizing company documents that can number tens of thousands of pages can take a very long time, and is even almost impossible if done manually.
However, with the ADF feature, you only need to insert documents into the ADF and wait for the scan results to complete without having to enter them one by one.

That's a brief discussion of the automatic document feeder feature on photocopiers along with an explanation of how it works.. Hopefully the brief description above can provide additional useful knowledge for you about this issue.
