Describe connecting a network scanner. Connecting the scanner to a computer and creating an office network

Facebook

A system administrator, by the nature of his activity, needs to know: how many computers are on the local network he serves, their names and IP addresses, how many shared network resources(folders, printers, etc.) created. In addition, he needs quick access to any of these shared folders. But if there are a lot of computers on the network with shared resources, then this task is quite problematic.
Programs help solve this problem - resource scanners, which perform a monotonic exploration of the network and calculate nodes that share resources. One of the most famous such programs is (old name).

The program can be downloaded from the official website. It is paid, but there is a free trial period.

We install it as usual. During installation, you may also be prompted to install another utility: . Decide for yourself whether to install it or not. Personally, I don’t need it, because... There are no computers with wi-fi adapters on my network. So I unchecked this box:

After launching the program, you will be informed about how many days it will work in free mode - click the “ button Continue" ("Continue"):

The interface language can be changed to Russian. To do this, go to the “File” – “Language” item in the menu bar and select Russian.lng.

Let's get started with the program. First thing create a new goal, for which you need to select the menu in the top list Target – Add:

Enter any target name: I named “ My network ”:

In the window that opens, write a name that is clear to you: for example, “ Office network " Next, indicate the range of addresses that need to be scanned (you can use the “Find IP range” button). Click OK:

After the address range is specified, to start scanning the network, you must select the menu in the top list Scanning – Scan:

The scanning time depends on the size of the range, the number and type of resources found, etc. In the status bar below you can see the scanning progress indicator, as well as the number of addresses and computers that have already been scanned.

After your network has been scanned, the names of all computers and their IP addresses will be displayed on the screen. If any of the computers has a shared resource, a check mark will appear to the left of it. By clicking on it, we will see a drop-down list that lists all the shared resources of this computer: shared folders, printers, etc.

In this example, on a machine named COMP there is a common Canon printer and general Users folder. We can open this folder directly from this window by double-clicking.

This is how it turns out: computers with shared folders are located on different floors of the building, and we see them all at once in one window and can go to any one.

It has quite a lot of settings with which you can influence the appearance of the interface, scanning parameters (for example, add a check for the presence of FTP and HTTP servers), and display of information.

The program (old name) can be called an indispensable tool for finding the necessary information on local networks in a minimum time.

How to make a network scanner?

Master's answer:

A local network that connects several computers within one organization has some advantages in use: accessibility to common applications and files and the ability to share equipment: scanners, printers.

To make the scanner network-ready, you can use the RemoteScan 5 application. To do this, you need to download this program from the address: http://www.cwer.ru/node/6585/, then install it on each computer on the network. Accordingly, on the PC to which the scanner is connected - the server version, and on other personal computers to which the scanner needs to be connected via the network - the client version.

Please note that during the installation of the client version of the program, a message may appear stating that the scanner is missing. No need to pay attention to this. After completing the installation of the server part of the program, you need to right-click on the program icon in the tray in order to be able to use the settings.

You can then select your scanner and configure the ports to connect to it. Keep in mind that it may take up to three minutes to identify any device. If this does not happen, then this scanner model is not supported by the application.

Wait until the icon is no longer crossed out. After this, you should open your antivirus program/firewall and allow access to the scanner port. The default is 6077. If you have NOD32 antivirus installed, then you can go to your personal firewall, open settings, select interactive mode and start creating a separate rule for the RemoteScan program. You need to install the client version of the application on the appropriate computers, add special software and scan over the network.

Perhaps using another program to share the scanner on the local network will help if the previous application did not detect your scanner. To do this, you need to download the Blindscanner program, go to http://www.masterslabs.com/ru/blindscanner/download.html, select the desired version, download and install the server and client versions of the program on your computers, respectively. Perform the setup in the same way.

The Internet is replete with articles on the topic of setting up shared access to printers, but finding good instructions on the topic “How to set up shared access to a scanner on a local network” is quite difficult, which is why novice users encounter problems when solving the problem on their own.

The main feature in setting up shared access to a scanner is its drivers, which control the operation of the device. The user and the operating system interact with the scanner through drivers, so they must contain a mechanism to support shared access to the scanner for remote use.

To make sure that interaction occurs at the driver level, try launching a scan from a third-party application, be it the operating system's Fax and Scan tool or a graphics editor. Be sure to get into the proprietary utility from the scanner developers. Therefore, if this point was not taken into account at the stage of writing software for the scanner, which is important for older devices that are not supported by the manufacturer, then public access to such a scanner cannot be organized.

The technical documentation for the MFP should contain all the necessary information regarding the use of the peripheral device, including over a local network. If there is no such data or it is difficult for the user to understand it, this instruction will come to the rescue. It shows, using an example, how to connect and configure a scanner in the Windows operating system in order to scan documents over a network.

In our case, we used a PC with Windows 7 and an HP scanner. XnView and Blind Scanner were used as accompanying software to open public access to the scanner.

What is a network scanner?

Note that there are two methods to “share” the scanner on the network. The first is to connect the device to one of the computers on the network and configure it accordingly. The second is to connect the scanner to the network as an independent device and make the appropriate settings. The connection methods differ in that in the first case the device will not have its own identification number (IP address) by which other network users will access it. Requests will occur through the mediation of the computer to which the scanner is connected. We will focus on this switching method due to its prevalence and ease of implementation. The second case requires a special device that is equipped with an integrated network card for individual operation on a computer network, or a hybrid scanner. It can work either separately from a PC on a local network or connect to a computer via USB or Bluetooth.
The ability to use the scanner over a network requires that the computer controlling it be turned on and connected to the network.

Let's start setting up public access on the server

First of all, you should connect the multifunction device or scanner to the computer via USB and supply power to it, provided that the drivers are installed in the system. Otherwise, download them from the developer or device support website and install them. Then you should restart your computer and scanner.

Now you should install a utility with the option of scanning documents, if the system does not have one. You can use, for example, XnView.

Installing the application is very simple, so any beginner can follow all the instructions.

Client machine configuration

Then we switch to the computer from which we will perform network scanning and install the BlindScanner program on it, taking one point into account: in the component selection window, move the checkbox to the “BlindScanner Pro TWAIN driver (Client)” position.

Using the scanner over a network

As a result, we will receive a digitized document.

The task of how to scan over a network using a USB scanner is not as difficult and complicated as it seems to many users of office equipment at first glance. First, you will need to select a router and flash its firmware. Find out how to set up a network scanner or multifunction printer with scanning capabilities in more detail below.

First of all, download the “OpenWrt Backfire 10.03.1-rc5” firmware from any reliable web resource.

Start installing the firmware using a special recovery utility for your router model - usually Firmware Restoration.
Organize a connection between the router and your computer using any LAN port.
Put your router into recovery mode. To do this, turn off its power and press Restore or Reset (depending on what is written on the button of your device).
After that, turn on this device and hold the button until the power indicator starts blinking.
Settings related to IP addresses should not be made. You can only assign your personal computer an address that will be different from the standard “192.168.1.1”.
Open the firmware recovery program and first disable the firewall - if you do not do this, the utility will still urgently ask you to do so.
Select the previously downloaded firmware file, which has a .txt extension. After this, wait a few minutes until the installation comes to its final end and the router appears at the IP address “192.168.1.1”.

First steps to set up

At the first stage, change the router password in the corresponding tab.
Configure access to the World Wide Web and DNCP servers. If you are not satisfied with “192.168.1.1”, then you can safely change it. In the future, you will need to configure the device specifically for this IP address.
The next step is to configure the packages. Click on “Update package lists” and use “Filter” to find packages nano, sane-backends, sane-frontends, xinetd, kmod-usb-printer, and then install them. Once this process is complete, be sure to reboot the router.

Setting up scanning

To successfully solve the question of how to scan over a network using a USB scanner, connect to your router via SSH.
After that, you can either be lucky or not. In the second case, you will have to make additional settings.
Now you have to start editing “/etc/sane.d/xerox_mfp.conf”. Add these two lines to this file: “usb 0x04e8 0x341b” and “usb libusb:001:004”.
Save your changes, and then check if the configured scanner is detected.
At this stage, you need to start setting it up locally. Add this line “192.168.11.0/24” to the file “nano /etc/sane.d/saned.conf” - in this case you need to specify the subnet of your router.
A small change will also have to be made in the “nano /etc/xinetd.conf” file. To do this, you need to add “service saned” to it, then between the opening and closing brackets “(…..), enter this code (without quotes):

"socket_type = stream
server = /usr/sbin/saned
protocol = tcp
user = root
group = root
wait = no
disable = no"

Finally, launch xinetd in a mode called output. debug information. After this, you must make sure that the service is actually running. If this does not happen, then open the file “/etc/services” and if the line “saned 6566” is missing, be sure to add it.

Install SaneTwain

Download SaneTwain and install it. To do this, you need to run the file “scanimage.exe”.
After this, indicate the address of your router in the settings window that opens and restart the program.
Most likely, after restarting SaneTwain, you will encounter a server connection error. To solve this, pay attention to the “syslog” entry, which is located in the web interface. Then add a "host" entry with the name for the device's IP address ":~# nano /etc/hosts".
Add the line “192.168.11.1 OpenWrt” there, and then restart the xinetd add-on.
Reboot SaneTwain - maybe this time everything will work as it should.
Open your router's web interface again and enable xinetd autostart there.
Copy the second file from the SaneTwain archive, which is called “sanetwain.ds” and send it to the twain_32 folder, which is located at this path: C:\Windows.

Setting up printing

To configure printing, install the package called “luci-app-p910nd”.
Then go to the web interface and check the boxes next to Enable and Bidirectional mode. In the Device field, enter /dev/usb/lg0, and in Port, simply enter 0.
Then make sure that after rebooting the device the server starts normally.
Now set up the printer itself by filling in the fields with the port name and IP address. In addition, you will also need to enter the port number.
At the end, you can do a test print to make sure that all of the above steps were performed correctly and correctly.

If necessary, you can clear space on your router for other software applications. The idea is to remove all those backends that are no longer useful to you. To do this, connect via ssh. You can find backends here: “/usr/lib/sane/”. The most important thing in this matter is not to get carried away with cleaning and thus not to destroy the files that are really necessary for the normal operation of the equipment.

Thus, setting up a scanner via USB so that it can be used over a network is not so difficult. Of course, the average user may encounter a number of names that are incomprehensible to them, so it is very important to follow the instructions and strictly move step by step towards solving the problem.

Network printing works, but network scanning fails (Windows).

The network settings of the scanner driver may not be set correctly.
To resolve the issue, follow the instructions below:

NOTE: The illustrations below are representative of your product model and operating system and may differ from your Brother model and operating system.

Step 1: Make sure your Brother machine is turned on and there are no errors on the display.

If nothing appears on the display, your Brother machine is turned off or in sleep mode. Press any key to see if the device wakes up from sleep mode. If your device does not wake from sleep mode, make sure it is plugged into a working outlet and that all power buttons (if present) are turned on.
Check the display for error messages. For example, "Paper Jam" or "Out of Ink/Toner." If the display shows an error, correct it.

Step 2: Check your connection

To use the Network Scan feature, your Brother machine must be in a peer-to-peer network environment.

In a shared network environment, the scanning function is only available from the server computer and does not work on client computers.

Step 3: Check that your Brother machine can print

Step 4: Check your scanner driver

Open the list of scanners and check for the Brother machine scanner shortcut.

If you don't see a Brother machine shortcut in the list of scanners, you need to install the scanner driver.

Go to section Files on this website on the page of your device model and download Full package of drivers and software. Installation instructions are available on the download page.

Step 5: Check your Brother machine's IP address

You can check the device's IP address using the network configuration list.

Step 6: Set the IP address in the scanner driver

NOTE: Steps may vary depending on the operating system you are using.

If you have problems with the IP address, contact your system administrator to obtain the correct IP address.
Refer to the network configuration list printed earlier for how to set the device's IP address.
If Boot Method /IP Config is set to Auto, change it to Static. For details see User guide or Network Guide.

Step 7: Check your firewall settings

Check your firewall settings on your computer. If your computer has a firewall enabled, it may be blocking the network connection required for network scanning programs to function properly. Disable the firewall on your computer and try network scanning again.
If the network scanning feature works correctly after you disable the firewall, then the firewall was previously blocking the required network connection. In this case, Brother recommends that you disable the firewall each time you scan over the network using the scan key, or leave the firewall enabled by changing its settings.

If your firewall is blocking your network connection, it is recommended to add the following internal/external ports to your firewall:

UDP: 54925
UDP: 137
UDP: 161

Step 8: Uninstall and reinstall Brother drivers

Uninstall and reinstall Brother drivers.
For Windows XP SP2 or higher and Windows Vista: If the firewall discovery screen appears, select Change firewall port settings to allow network connection and continue with the installation. (Recommended) (Change the Firewall port settings to enable network connection and continue with the installation (Recommended)). You may need to click a button to continue. Next.
If you have Windows Firewall turned off, or if you are using a different firewall, you may receive a warning that the firewall has blocked the network connection. Add the following network ports according to the instructions in the documentation for your firewall.
To scan over a network: add UDP port 54925.
If network connectivity issues persist, add UDP ports 137 and 161.
Try scanning again to determine if the problem is resolved. If scanning fails:
Make sure your computer is not running any security software or firewalls that might block your network connection.
Try scanning from another computer connected to the network.

Today we'll talk about network scanning. Is it possible, of course it is possible. As you know, most MFPs do not have network scanning capabilities. That is, the scanner can only be used by one user sitting at the computer to which the MFP is connected. To be honest, in my practice, I have not seen an MFP that has the ability to scan over a network. But in large organizations network scanner or it would be more correct to say that a network scanner is simply necessary.

I came across networked MFPs that connect to the network, but they do not have the ability to use the scanner from several computers. And using standard means it will not be possible to achieve the ability to scan documents from several computers, and this is sometimes very necessary. Let's consider this situation: in some department where there are, say, three or four computers and MFPs. Setting up printing for all computers is not difficult.

But to do it network scanner so that every computer has the ability to scan documents will not work. Installing a scanner for each user is not very convenient, and it is also a costly affair. I myself came across a situation where I needed to make a scanner accessible over the network. I scoured the entire Internet and tried a bunch of programs. Most of them are paid, but they did not give money for purchase. After a long search I came across the BlindScannerPro program. With this program you can make a network scanner.

In order to configure the scanner to work on the network, you will need to download the BlindScannerPro program. The installation process should not cause you any problems, but just in case I took a few screenshots.

We agree to the terms of the license agreement and click next

Selecting disk space for the program

Here we choose whether to install a server or a client; we install the server on the machine where the scanner is connected.

After launching the program, you will need an activation key; you can download it at the end of the article. The client needs to be installed on those machines where the scanner is not connected. Next, we need to install the server, everything is the same, we just select the server and install it on the computer to which the scanner is directly connected. There are no special settings there, so I won’t write anything. Now you have network scanner. After you have installed the server and client, go to the computer with the client and launch ABBYY FineReader. There we click Service - Options, then go to the Scan/Open tab and select the BlindScannerPro driver and click OK. Next, click scan as usual. The BlindScannerPro Client window appears. Click on the plus sign and write the IP address of the server, that is, the computer to which the scanner is connected. A little lower from the drop-down menu, select the scanner that is installed on the server and click Scan.

The scanner usually comes with cords (power and USB cable), an update disk, instructions in electronic form, and sometimes software. All this will be useful to you to connect the device to your computer. In addition, the instructions below will help.

Connecting the scanner directly

To connect the scanner you need:

When the scanner is still not found by the computer, you should simply move the cable to another connector. If this does not help, you will have to turn off all the wires, remove all updates for the scanner from the PC and start the project again from the second point.

Scanner that works on multiple computers

If there are many personal computers on your network, to connect you need:

Check the presence of the “Ethernet” connector on the scanner and insert the required wire there.
Organize your workspace so that the wireless network covers all the necessary computers.
Connect the router and place it next to the scanner (the closer, the brighter, clearer and faster it will work).
On your computer, follow the operating system recommendations.
Connect your PC to the network scanner.

The last item in the list can be described in more detail:

Go to “Start”, go to “Control Panel” and then click “Devices and Printers”.
Now click on “Add a printer” and “Add network, wireless or ...”.

A search will be made for all nearby devices, from which you will need to select the one you need.

Add a Printer Window

Failed to install scanner

There can be many reasons. For example, you did everything according to the instructions, but the scanner does not want to perform its direct duty just because the transport switch is set to “Closed”. And this is the easiest case to solve. If you bought this scanner secondhand, it is quite possible that the previous owners had a power failure and the electronic elements could not stand it.

The problem may be related to the drivers. It's worth trying to install them again. And it’s best to contact a specialist who will tell you what condition the equipment is in. If the equipment is new and has not been negatively affected, the product may be defective. It's worth going to the store and exchanging the scanner for a new one.

Video setup of the scanner driver on a PC with Windows 8

After installing the scanner on a computer running Windows 8, you may see an error - “The scanner cannot be connected.” In the following video, the wizard will tell you which driver you need to install to solve the problem:

Follow the prompts of the Installer Wizard and click “Next”. We agree to the license, and in the options window, check the “Install Server Software” box.

The program instance will be installed in server mode, which will enable other PCs to use the network scanner.
At the next stage, you need to make sure that the checkbox is checked, as in the screenshot.

IMPORTANT! The firewall may prompt you for permissions for the program. In this case, it is recommended to allow the program on all networks.

Launching the server version

You just need to select your scanning device so RemoteScan can share it. Double click on the required device.

The program will be minimized to tray and will then launch itself when you turn on the computer.

If you need to reconfigure the scanning device, you can always do this by right-clicking on the RemoteScan program icon and selecting “Choose a Scanner”.

As you can see, using the program is quite simple.

Installing the client version

Installing the client part is similar to the server part, with the only difference that now you should check the “Install Client Software” checkbox.

You also need to allow it to work on all networks if the firewall asks.

IMPORTANT! Firewalls of some antivirus programs block ports 6077 and 6078, which are necessary for the program to operate. It is necessary to add to the exceptions the exe file of the program itself (on the server) and the above-mentioned ports (both on the server and on the client).

Network scanning

Use a scanning program you are familiar with or, for example, install WinScan2PDF. It is very small and does not require installation. Designed for scanning images to PDF files only.

After turning on the scanner, you must install the driver for this device so that data can be transferred between the computer and the scanner. Start by connecting the scanner to your computer's USB. (Read your scanner's manual to find out how to connect it to your computer.)

Changing scanner settings

After installing your scanner, you may want to review your settings or change the default settings. To do this, run the command Start>Control Panel. In the search box in the Control Panel window, type scanner and press .

In the control panel window, click on the link that appears View scanners and cameras.
In the window Scanners and cameras A list of installed scanners will be displayed. Click first on any scanner in the area Scanners and cameras and then on the button Scan profiles.
In the dialog box Scan profiles select the scanner and click on the button Change. In the dialog box Change default profile, review the settings, which may include (depending on your scanner model) color management to correctly reproduce scanned colors and set resolution. (The higher the resolution, the sharper and cleaner the electronic document will be, but it may take longer to scan.)
Click the button Save profile, and after returning to the properties dialog box, double-click on the button Close to close the windows Scan profiles And Scanners and cameras.

Once you are ready to turn on the scanner, place the document you want to scan into it. Depending on your scanner model, this document may be placed on the scanner and covered with a lid, or fed through a tray. Look in the scanner instructions on how to start the scanning procedure (for example, click on the Scan or Start). The computer will automatically detect when the scanning process has begun, display a dialog box showing the progress of the scan, and prompt you to view and save the scanned item.
