I solved my problems and the printer/scanner DCP-j140(wifi) is working well unther Linux Mint 13 (Maya LTS = "Ubuntu"):
I installed it unther a plain/fresh Mint installation. So first You have to remove the not working printer(s) within the system...
Then You have to download the drivers:
Select the Brother DCP-j140w drivers. They should result in the directory Downloads
with the following 2 deb files:
Use bv/ag. the Clamtk anti-virus tool to check these .deb files against viruses or malware. Hence! You downloaded them outside the protected area. (Also use the rkhunter...)
( sudo apt-get install clamtk
sudo apt-get install rkhunter
sudo rkhunter --update
sudo rkhunter --propupd
and scan with sudo rkhunter --check --sk
Probebly the rkhunter will react with some false "positives",
so don't panic. Check them out with Google. This is my rkhunter result:
System checks summary
File properties checks...
Files checked: 139
Suspect files: 1
Rootkits checked : 245
Possible rootkits: 0
All checks skipped
The system checks took: 1 minute and 55 seconds
All results have been written to the log file (/var/log/rkhunter.log)
One or more warnings have been found while checking the system.
Please check the log file (/var/log/rkhunter.log)
Look at this result: Possible rootkits: 0
It always should be zero. If it is not zero then You've got a serious problem.
You have to shutdown and install Linux "fresh" again.
Then start a console, the "DOS"-enviroment of Linux...
From here copy/paste all letterly:
sudo apt-get install tcsh
sudo mkdir /var/spool/lpd
sudo dpkg -i --force-all dcpj140wlpr-1.1.3-6.i386.deb
sudo dpkg -i --force-all dcpj140wcupswrapper-1.1.3-6.i386.deb
Linux/Mint/Ubuntu installed the USB-version of the DCP-j140w.
dpkg -l | grep Brother
You should get a output like this:
ii dcpj140wcupswrapper 1.1.3-6 Brother CUPS Inkjet Printer Definitions
ii dcpj140wlpr 1.1.3-6 Brother lpr Inkjet Printer Definitions
ii printer-driver-ptouch 1.3-3ubuntu0.1 printer driver Brother P-touch label printers
Go to System/Hardware/Printer-configuration:
And You see the usb-version of the DCP-j140w installed.
In the URI You see the USB-link...
If this printer was working well unther Windows/Android, it should work unther
Linux as well...
Go to New Printer and wait until You see something like this:
Select that one and delete the all the previous versions of the J140W.
After that select printing a testpage:
Within Wifi it should print an Ubuntu testpage...
And now the scanner:
You have to download the scanner .deb files first on:
Find them in the Downloads dir, named as:
They are downloaded out of the secured enviroment. Check them first.
I can't say this often enough... On internet thrust nobody, only You're selves.
On Linux Mint Xsane is installed properly. If not You have to install Xsane
sudo apt-get install xsane would do. Don't ask, copy/paste and execute...
Then type (copy/paste):
sudo dpkg -i brscan4-0.4.2-1.i386.deb
sudo dpkg -i --force-all brscan-skey-0.2.4-1.i386.deb
To check out:
dpkg -l | grep Brother
Then whe have to find out the IP-address of ou're printer.
Therefore whe install this:
sudo apt-get install nmap zenmap
To check out: sudo nmap 192.168.1.*
Look for the ip-address where in is a item like this:
xxx/tcp open printer. That's the right one.
Note that ip-address: that's Your'e printer. All right!!!
Or use Zenmap (in root/sudo:)
If whe know the ip-address of the printer whe finally end with:
brsaneconfig4 -a name=SCANNER model=DCP-j140w ip=xxx.xxx.xxx.xxx
(Where xxx = the ip-address of the printer.
Startingup Xsane should now work properly.
Enjoy working with You're Wifi printer/scanner,
