Brother MFC-J4510DW scanner problem
 

Ok I am a newbie here and having the darndest time trying to get my printer/scanner to work I have followed all of the steps as to what to download in order to get it to work but nada. I got the printer portion of it working fine. But the scanner wont work no matter what I do. Xsane gives me a brother4:bus6;dev1':Invalid Argument, error and on Gscan it comes up error opening device: Invalid Argument. PLEASE HELP I dont have much hair left.:newbie: Thanks in advance. Dan and if this is in the wrong area please set me straight. Thanks again

A few questions.

What distro and release?

After installing the driver, are you able to access the scanner as root user? Can you post the link to the instructions you followed to install the driver. ( I'm guessing you followed the instructions on Brothers web site ), just want to make sure.

What groups does your user belong to? This can be difficult. Some distros you may need to belong to the scanner group, others do not make you belong to that group; lp group only.

Sorry but I am so new to this stuff i have no idea the answers to your questions. I did download the drivers for the scanner and printer got the printer to work fine. When I try to scan using Gscan i see the scanner for a split second then it says Error opening device Invalid arguement. When I use Xsane it also gives me a Invalid Argument message. Im sorry I dont know much about this stuff yet. And yes i did download them from the Brothers website.Thanks Dan

Well, the user who wants to use a multifunction device must be member of both, the lp and the scanner group. Please open an terminal and execute the command and post the output here.
You can as root execute which will show you the available devices. There's also a commandMarkus

I understand your lack of experience. If you could post Markush's requests, that will help. If you need guidance on how to make a command happen, please ask.

This link -->http://welcome.solutions.brother.com...nload_scn.html lists the printer and scanner driver for your MFP.

Is this device USB or network connected? Did you update the udev rules according to the instructions here? -->http://welcome.solutions.brother.com...ion_scn1c.html

yes please help me with the command thing. I dont understand any of it. thank you guys for helping so far. And it is a USB.

Well, do you know how to open a terminal? There should be an icon anywhere on your desktop which looks like a Computermonitor or the DOS-shell in Windows.

I dont know how to open a terminal either. And I dont see what you are describing anywhere.

Dan,
The instructions given are correct.
To be able to type the the commands you need to be in a terminal (text only interface (black window with a cursor to type at)).
To get into the terminal (Goto the prompt so to speak) try typing Ctrl+Alt+T all at once.
then type in the commands followed by pushing the enter key.

OK figured out how to open a terminal now what should I do. Thanks again for being patient with me.

First type at the terminal prompt and press the enter button, then copy the ouput and past it into your next posting here.

flyerdan69 adm cdrom sudo dip plugdev lpadmin sambashare

yup, here we are, you'll have to add the user to the lp and scanner group. Execute the following command in the terminalAfterwards please execute the "groups" command again and look at the changes.

Markus

Sorry, I made a mistake, there must be a comma between the groups

Code:

---

sudo usermod -a -G lp,scanner flyerdan69
