In my earlier guide, I talked about converting USB printer/MFD to network printer via Raspberry Pi here. As promised, in this part I will tell how to setup the same MFD as Network Scanner using Pi.
The guide is as following:
You should get some output like this:
If the program returns information about your make and model like above, you're good to go.
Next, try the following:
You should get output like this:
Finally, try scanning something. Put something inside the scanner enter this command:
Now we know that the scanner is working locally, we can set up the sane daemon. Open the configuration file /etc/default/saned and set this option to turn the sane daemon/server on:
Next, open the file /etc/sane.d/saned.conf and add this line, which tells the server to accept connections from all IP addresses in the range 192.168.1.1 to 192.168.1.255 (or 192.168.0.1 to 192.168.0.255 depending upon your ip):
Also uncomment this line:
We also need to fix the permissions so that the sane daemon can access the scanner without root. Part of the output from sane-find-scanner was the following line:
The section "at libusb:001:005" at the end tells us that the scanner is located at /dev/bus/usb/001/005. Let's check who owns that file:
As you can see, it is owned by root with the group lp (linux printing). We need to add the sane daemon to the lp group to give it the necessary permissions:
Now restart the SANE daemon to make all of the changes take effect.
And tell the SANE service to start automatically when the Pi starts.
Now check SANE is running properly:
You can also check that the port is available externally by using nmap to port scan the Pi from your laptop:
(again, assuming print-server is the hostname of your pi - alternatively, use the IP addresss).You shoudl get results like this:
All good: the Pi has services bound to port 22 for SSH, 631 for printing/CUPS and 6566 for scanning/SANE.
You can use any scanning application depending on your OS, whether Windows, Linux or Android.
You can use any scanning apps from here...
The guide is as following:
Server Configuration:
To get started, log back in to the Pi with SSH or directly and install SANE and find your scanner:
Code:
sudo apt-get update
sudo apt-get install sane
sudo sane-find-scannerYou should get some output like this:
Code:
pi@print-server ~ $ sudo sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
# Also you need support for SCSI Generic (sg) in your operating system.
# If using Linux, try "modprobe sg".

# Your USB scanner was (probably) detected. It may or may not be supported by

# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.If the program returns information about your make and model like above, you're good to go.
Next, try the following:
Code:
sudo scanimage -LYou should get output like this:

Code:
scanimage > ~/test-scan-file.pnmNow we know that the scanner is working locally, we can set up the sane daemon. Open the configuration file /etc/default/saned and set this option to turn the sane daemon/server on:
