[SOLVED]...Brother MFC-440CN Scanner Issues

dbrew4 · 08-02-2015, 07:11 AM

Is there any issue running Simple Scan or gscan2pdf in ROOT? When I try to run these programs in normal they don't recognize my scanner (printer works fine)? They work fine in ROOT. Xsane works in ROOT but when I save a file to pdf I don't have permission to open it with document viewer. While reading numerous posts in numerous forums I understand there can be issues with Linux Mint 17 recognizing scanners. I'm a newbie and I don't have the skills to change files as recommended by some posts. If the directions were simple, I think I would give it a try.
Tks

Hi...

Welcome to the forum

This does sound like a permissions issue. What is the exact error message you receive when you try to use xsane in your regular user account?

Just as a possible quick fix, you can try installing the following packages in your package manager, if you don't already have them: sane, libsane and libsane-extras.

Regards...

Message when opening xsane as a regular user

Hi...

Do the instructions here help?

Remember that "yourusername" and "allyourgroups,commaseparated" in the instructions mean your personal username and groups (separated by a comma) on your system.

Here is mine using "groups yourusername", as an example...

Code:

aaron@aaron:~$ groups aaron
aaron : aaron adm cdrom sudo dip plugdev lpadmin sambashare
aaron@aaron:~$

Let us know how it goes...

Regards...

Check that you have a udev rule for assigning the correct device permissions as explained for Ubuntu (=Mint) users here:

http://support.brother.com/g/s/id/li...rect=on#u13.04

dbrew4 · 08-03-2015, 08:25 AM

this is what I got when I followed your command:

db@db-EX318AA-ABA-SR1920NX-NA630 ~ $ usermod -G db,lp,db
Usage: usermod [options] LOGIN

Options:
-c, --comment COMMENT new value of the GECOS field
-d, --home HOME_DIR new home directory for the user account
-e, --expiredate EXPIRE_DATE set account expiration date to EXPIRE_DATE
-f, --inactive INACTIVE set password inactive after expiration
to INACTIVE
-g, --gid GROUP force use GROUP as new primary group
-G, --groups GROUPS new list of supplementary GROUPS
-a, --append append the user to the supplemental GROUPS
mentioned by the -G option without removing
him/her from other groups
-h, --help display this help message and exit
-l, --login NEW_LOGIN new value of the login name
-L, --lock lock the user account
-m, --move-home move contents of the home directory to the
new location (use only with -d)
-o, --non-unique allow using duplicate (non-unique) UID
-p, --password PASSWORD use encrypted password for the new password
-R, --root CHROOT_DIR directory to chroot into
-s, --shell SHELL new login shell for the user account
-u, --uid UID new UID for the user account
-U, --unlock unlock the user account
-v, --add-subuids FIRST-LAST add range of subordinate uids
-V, --del-subuids FIRST-LAST remvoe range of subordinate uids
-w, --add-subgids FIRST-LAST add range of subordinate gids
-W, --del-subgids FIRST-LAST remvoe range of subordinate gids
-Z, --selinux-user SEUSER new SELinux user mapping for the user account

now what?

after downloading and saving the recommended file (brother-udev-rule-type1-1.0.0-1.all.deb, ver.1.0.0-1, 2KB)
This is what I got with the command

db@db-EX318AA-ABA-SR1920NX-NA630 ~ $ dpkg -i brother-udev-rule-type1-1.0.0-1.all.deb
dpkg: error: requested operation requires superuser privilege

Now what?

I sure wish there was a Linux hotline to call in order to have someone walk me through this...difficult with emails, post, etc....especially to a newbie.

You need to install as superuser (as with most administrative tasks), so use sudo

Code:

sudo dpkg -i brother-udev-rule-type1-1.0.0-1.all.deb

Installed dpkg -i brother-udev-rule-type1-1.0.0-1.all.deb

System still not recognizing scanner as normal user

Hi...

There are these services available but they tend to be for corporate users and you have to pay for them.

Did you use "sudo" at the beginning of the command? Example...

Code:

sudo usermod -G allyourgroups,commaseparated,lp yourusername

dbrew4 · 08-03-2015, 05:17 PM

this is what I got from that command

what is your thoughts on using Hexchat and using the Linux Help Chat room?

Hi...

Hmmm, something isn't right. Please show me the exact command you're typing in.

Thanks...

The udev rules are designed to provide read/write access to users who are a member of the 'scanner' group, so as ardvark71 has suggested already, you need to make sure that this is the case.

The following utility should find a USB-attached scanner

Code:

sane-find-scanner

Try running it as regular user, then using sudo.

dbrew4 · 08-04-2015, 06:02 AM

This is the command I used for "usermod -G allyourgroups,commaseparated,lp yourusername"

sudo usermod -G db,lp,db

my user name is db but I don't know what "allmygroups" is. I also ran "sane-find-scanner" and here are the results:

# 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.

I also ran "sane-find-scanner" in ROOT and here are the results:

# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

Hi...

It's what I suspected, the command you're entering appears incorrect. You don't put you username "db" directly after the "-G."

You find out what all your user groups are by entering...

Code:

groups db

Also, please post the output of...

Code:

lsusb

That should help us determine the which of the devices is your scanner/printer.

Hang in there, learning a new operating system can definitely be a challenge. I struggled when I first started learning how to use Linux, too.
