(First should you but ask if you ever still requires a scanner: If you (letters, invoices, etc.) want to scan only a few small documents, satisfies a probably recognize as home users a scanner app for the smartphone apps. the edges of a photographed paper, it circumcised and convert it into black / white, color or grayscale Such scanner apps are sometimes even more meaningful than a flatbed scanner:. If you want to scan multiple pages of a book, for example, is the photographing with smartphone much (!) quicker and easier than if the book ever has to take from the scanner down to flip again. Before you spend 80 for a flatbed scanner, you should even try if a scanner App suits your needs first. Images can be with Of course not scan such apps in good quality graphics also make problems, because lines can easily distort the photographing perspective -. technical drawings or geometry worksheets therefore one can also not scan with such an app).
1. Problem of the low depth of field
The LiDE scanner use a CIS sensor (LED technology). These have a depth of only about 1mm. That is, if the scan objects will not lie completely flat on the scanner glass of the scanning focus. Scanned text is then washed out and difficult to read. The problem occurs primarily in books because the paper is curled to the top of the book fold. However, magazines with curled copies or paper that has gotten a few drops of water can cause problems. Consequently, you have to the books when scanning relatively strongly press on the Scan pane (Some reviews report of creaking noises during scanning because the scan carriage is easily pinched by the high pressure. It would not need so much press when the depth of field would be higher).
Scanner with CCD sensor usually have a higher depth of field. Most scanners are not built with higher depth of focus for technical reasons as flat and mostly also need a separate power supply.
2. The driver support of Canon
One needs to look only on the used market. There are a few years old scanner (which is also an excellent scan quality were) sold off for a few euros because the manufacturer 7 or 8 no longer offer drivers for Windows. In my opinion, one main goal is thus pursued: the customer is forced again to buy a new device. Ultimately make all manufacturers that way. Canon is my experience when driver support but especially stingy. It may therefore well be that these scanners already on the next version of Windows for electronic waste.
I have maybe been, still offer which scanner manufacturers current drivers for their old devices: In my opinion, obtained for example Epson scanner for an extended driver support as Canon scanners. I can myself as well as wrong - after all, I've only randomly old scanner on driver support checks. If you are in any other opinion, I ask you to write a comment. I want to have simply mentioned the driver problem, because the Canon scanner to date are the hottest sellers in Amazon and hold most customers probably will not after other manufacturers out.
