How does a computer scanner work?

Scanner works quiet similar to the technology used by Photo Copier and Fax machines.\n\nThe Scanner Lamp scans the document/picture, it then sends the data to the computer.  Computer reads the data using the TWAIN (Scanner Driver) and it converts the information in to JPEG format or any other format as specified.\n\nFor Detailed information of How a scanner works click on the below link and it will give you better information.\n\nhttp://computer.howstuffworks.com/scanner2.htm

1. Click start --> run -->  "sfc /scannow" --> OK\nThis will take about 30 minutes and it does a system file check.

Well you've got a virus or spy-ware or both.  You need some software in order to clean you system.  \n\n1) Get an AntiVirus.  AVG by GriSoft (http://free.grisoft.com) is a good FREE one.  BE SURE to set up the auto-updates to make sure your scanner is up to date at all times.  Though sometimes the Anti-Virus program can get infected when you install it.  If that happens, the only thing you can do is a low level format of your HD and reinstall windows and everything.\n\n2) Get some good Anti-Spyware programs.  If you are running Windows then the MS AntiSpyware is pretty good (based on a program called 'Giant', and there's AD-Aware, and SPyBot (you can find those by a google search)\n\n3) BE CAREFUL of what Email attachments you open.  You can't get a Virus just by downloading an Email, you must open the attachment.  9 times outta 10 this is how you \nget infected.   IF someone sends you an Attachment.. VERIFY with that person that they sent it before you open it.  And if you get an Email from somone you don't know.. just delete it.\n\n4) Get a firewall if you don't have one.  If you are connected to the internet though a Router. you don't need\na software firewall.  ZoneAlarm is a good free firewall.

Have you restarted the computer?  Try that and see if anything helps.  If not, click on the website below.  You may have to uninstall the scanner and reinstall it.

Find the web site of the manufacturer and download the appropriate driver software for your scanner and operating system. Install the software and your system should then recognize the scanner.

The scanner sends out a laser beam that reflects against the barcode on the object. The scanner is programmed to recognize the reflections of barcodes and use those to identify the product.

Machine code. The computers internal programming recognizes a connection from a keyboard via the ps2 connection or whatever you have(usb etc..). When you press a key on the keyboard a signal corresponding to that key is then sent to the computer and then is translated and then displayed on your monitor. Much like it is displaying every single character I am typing this very moment. Your computer receives and displays these signals almost instantly. Cool eh? :)

how is it connected to the computer would be my first question. Contact the manufacturer for a spec sheet or api for the pole display. same goes for the bar code scanner inputs.

Potential problem is:\n\nDriver, connection, IRQ, software, compatibility of driver and operating system.  Without specific error message, it is hard to find out why your scanner is not working.

Depends..\n\nIf you're wanting to get new photos on the computer, then a digital camera is the choice.\n\nIf you're want to empty the photo albums and get them digitized, then you need a scanner.\n\nAnd if you want to do both and you're on a tight budget, buy a $100 Scanner and spend a couple hundred on a digital camera.  And you'll have a good mix.

Hi there Ashish,\n\nFirst of all, I would like to make clear that a scanner is used to 'scan' whatever we put on that 'glass screen'. However, in Windown XP, you have a scanner wizard which provides you with options like 'grayscale' or 'color'. I think that will be the maximum we can modify the image 'while' scanning. However, after we scan the image, we can edit the color or other things by softwares like Photoshop or Nero Photosnap. There are various softwares available on net for this purpose. The 'Paint Dot Net' released by microsoft is also quite user-friendly. \n\nSo remember, a scanner is a device that is used to transfer external images to our pc. Any changes we make to the image before or after scanning won't be considered as the changes made by the 'scanner'. We change the settings via our PC.\n\nHope this answered your query. If not, pleae let me know, and I'll be glad to be of further assistance. Bye!!\n\nrule wid style n luv@vinny.

Anyone attempt the open ports on your pc to launch an attack is considered a port attack. Details on port scanning and all follow:\n\nThe act of systematically scanning a computer's ports. Since a port is a place where information goes into and out of a computer, port scanning identifies open doors to a computer. Port scanning has legitimate uses in managing networks, but port scanning also can be malicious in nature if someone is looking for a weakened access point to break into your computer.\n\nTypes of port scans:\n\n    * vanilla: the scanner attempts to connect to all 65,535 ports\n    * strobe: a more focused scan looking only for known services to exploit\n    * fragmented packets: the scanner sends packet fragments that get through simple packet filters in a firewall\n    * UDP: the scanner looks for open UDP ports\n    * sweep: the scanner connects to the same port on more than one machine\n    * FTP bounce: the scanner goes through an FTP server in order to disguise the source of the scan\n    * stealth scan: the scanner blocks the scanned computer from recording the port scan activities. \n\nPort scanning in and of itself is not a crime. There is no way to stop someone from port scanning your computer while you are on the Internet because accessing an Internet server opens a port, which opens a door to your computer. There are, however, software products that can stop a port scanner from doing any damage to your system.
