Generally, scanners are devices which don’t hold much information. However, there are some commercial-grade scanners which may store data about you. These devices are big and expensive, and they usually come with other functions.
Businesses and offices usually have these kinds of multifunctional equipment. This feature also happens to be essential. It’s especially important for the purposes of backing up important information.
On most scanners and printers used in the home, the memory the devices have of the printing and scanning jobs are in short-term memory. When you turn off your scanner or perform another scan, the memory of the previous task gets flushed out.
There are cases though, that your personal information gets stored. This happens when you set up your scanner initially. This is especially true if your appliance has faxing capabilities. The stored information may include your own fax number, other phone numbers, and any numbers you saved on speed dial.
If you’d like to check what data gets stored in your scanner or multifunctional device, take a look at the setup menu. The storing functions are different for varied kinds of scanners, so checking the manual is important. If you can’t find your device’s manual, you can go online and try to search for the manual there.
A lot of manufacturers make digital copies of their manuals on their websites, free of charge. If your device comes with a speed dial function that stores information, you can find the reset procedure on the manual. When you reset the device, it erases all stored data and goes back to its factory settings.
Types of scanners
Just like any other equipment, there are different types of scanners in the world. Choosing the best one for yourself depends on what you plan to use it for. All these scanners have different purposes and different features. We’ll go through these types so you can determine which one will best suit your needs.
These types of scanners take up a lot of space on your desktop. But the great thing about them is that you’ll definitely get great value for your money. Flatbed scanners look like small printers. They have a cover that flips open to keep the glass plate securely underneath.
Flatbed scanners come in different sizes. Usually, they are big enough allow for standard documents or legal-sized ones. The flip-up cover is flexible so you can even use the scanner for bigger items such as textbooks.
These types of scanners are ideal for scanning photographs, books, magazine or newspaper articles, and documents. Oftentimes, manufacturers incorporate flatbed scanners into multifunctional printers.
This type of scanner is primarily for making slides or film negatives digitized. Although this scanner comes at a higher price, it performs unique functions. These functions are specific to photo scanners and other scanners cannot do them.
Photo scanners come with specialized internal technology. That’s why they can work with negatives and slides. They also come with a built-in special software. This software allows you to restore old photographs. These types of scanners produce resolutions which are brilliantly high as compared to other types of scanners.
These types of scanners are smaller than the flatbed ones. Unlike the flatbed scanner, you don’t place the document on top of the scanner for scanning. With a scanner like this, you feed in your photo or document for scanning. The scanner has a document feeder which is automatic.
A sheetfed scanner won’t take much space from your desktop computer. However, it may produce a lower resolution than other scanner types. If all you need to scan are documents, then this scanner is good enough. It’s also great for scanning documents because you can feed them into the scanner by batch. With this, you don’t have to scan your documents one at a time.
As the name suggests, portable scanners are small enough for you to bring them everywhere. Some of the best portable scanners are available in different shops, even online. These types of scanners also come in different sizes. Some are even so small that you can put them in your pocket!
Portable pen scanners are bigger than regular fountain pens. With them, you can scan text on a document, one line at a time.
Some portable scanners are as wide as the whole page. With these, you can roll down the page to scan the text. One setback of this type of scanner is that it doesn’t produce high-quality scans. This means that it’s not ideal for scanning photos or for other similar applications.
The good thing is, they’re a lot cheaper than other scanners. So if you’re looking for a simple, budget-friendly scanner, you can go with a portable one.
Are there scanners with internal memory?
The short answer is, most scanners don’t have an internal memory. As we’ve explained previously, scanners store your most recent jobs, but only for a short time. Then, when you scan a new document, the old one gets replaced. There are scanners which come with internal memory. These come in the form of internal hard drives.
Scanners like these are typically used in offices or big corporations. Also, manufacturers incorporate these scanners in other devices, making them multifunctional.
Corporations use scanners and multifunctional devices with internal hard drives for different reasons. They may need to store the documents or items which get scanned or copied each day. Typically, they would need to keep a copy of the scanned items for filing and backup.
The downside of this feature is that other people may gain access to these stored documents. There are many cases wherein hackers and other nefarious people salvage sensitive information. They do this by tapping into the hard drives inside commercial scanners, printers or multifunctional devices.
On average, it’s quite easy to recover information from hard drives from scanners or other big devices. This is a potentially dangerous issue which corporations have to recognize. So, before doing anything else, make sure to have all the information on the hard drive erased.
Do this before returning, recycling or selling the device. With simple scanners though, this isn’t an issue. They don’t have an internal memory which stores sensitive information so you don’t have to worry.
