Portable high-speed scanners are characterized by energy conservation, environmental friendliness, multi-functionality and small size, and are suitable for mobile office work. With the rise of the concept of paperless office, the application fields of high-speed scanners have also been widely spread across various industries. Although the use of high-speed scanners is becoming increasingly frequent, there are still some users who have little understanding of some concepts related to high-speed scanners. Given that users have inquired about which file sizes can be captured by high-speed scanners, we will now provide answers to this question for everyone.
What is a format?
The format refers to the graphic area composed of the width and length of the drawing sheet. When drawing patterns, the specified basic format dimensions of the drawing sheet should be adopted. The unit of measurement is mm. The basic format codes include A0, A1, A2, A3 and A4. There are five types in total.
The ratios of the long and short sides of all the drawings are consistent, each being 1.414213562, which is the square root of 2. In other words, if the size of a drawing is one unit larger than the previous one, its area will be twice as large.
For example: The size of A0 is 1189mm × 841mm, that of A1 is 841mm × 594mm, that of A2 is 594mm × 420mm, that of A3 is 420mm × 297mm, and that of A4 is 297mm × 210mm...
A4-size scanner
The A4-sized paper is surely familiar to everyone. It is the most commonly used file size in office work. Its size is 210mm × 297mm, defined by the International Organization for Standardization. The high-resolution scanner with A4-sized paper input function can capture files of A4 size or larger. For files smaller than A4 size such as A5 (148mm × 210mm) and A6 (105mm × 148mm), the high-resolution scanner can also be used for scanning. For example, the Fenglin high-resolution scanner has a maximum input size of A3. The size of the document platform of this device is slightly larger than A4. If the file size exceeds the document platform, the excess part cannot be displayed and a larger-sized high-resolution scanner needs to be replaced.
