The Cannon Pixma MG2450 printer has an integrated scanner that should work with a tool like Simple Scan (or Xsane, Skanlite).

I have the proper drivers (provided by Canon: scangearmp-common and scangearmp-mg2400series) and I was under the impression that with them the scanner worked in the past, but now Iţm not so sure... after trying and failing to make it work...

As seen here, the Cannon Pixma 2400 series look supported.

I cannot access the scan in Linux: I have tried to access it in Ubuntu and other *ubuntu-based systems like Linux Mint 17.2 KDE and elementary OS Freya.

The scanner cannot be faulty, because it works in Windows (I have multiple boot).

How could I investigate this farther?

Can I be wrong that this scanner is supported and that it worked in the past?

The printer works.

But is this scanner really supported ?

etc/sane.d/dll.d contains only these two files:

Also:

      sudo sane-find-scanner

[sudo] password for cip: 



  # 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.



  # No USB scanners found. If you expected something different, make sure that

  # you have loaded a kernel driver for your USB host controller and have setup

  # the USB system correctly. See man sane-usb for details.



  # Not checking for parallel port scanners.



  # Most Scanners connected to the parallel port or other proprietary ports                                                                                                                          

  # can't be detected by this program.  

Trying to start skanlite tool in terminal, I get:

 skanlite

Bus::open: Can not get ibus-daemon's address. 

IBusInputContext::createInputContext: no connection to ibus-daemon

etc/sane.d/ddl.conf contains some lines starting with cannon, one pixma, none is commented out.

Edit after a first answer:

The situation is a bit confusing so I try to follow the most simple part, the one about installing the scanner drivers first:

if you install first the scanner, when you turn on the machine, after
installing the driver, mint installs the printer. Again you have to go
to Menu-Administration-Printers and eliminate the printer mint
installed for you. Then you can install the canon printer driver, this
time without interruptions

Using the debian packages instead of the deb files I get indeed a second entry in the printers list but there is no way I can make it disappear forever: any time I re-connect the printer, a second one is added. Removing it manually I have only the one installed by me but only until I reconnect the printer. Even so, the scanner doesn't work.

Anyway, the printer is not added automatically unless the Canon drives are installed!

Have you tried this?

This is how a chap by the name of Eduardo got it to work.

What it says is this:

First, the scanner has no support by sane, so mint can't install it by
itself. There is no problem with the printer, gutenprint driver works
great. As soon as you connect and turn on the printer, mint installs
it, but there is no scanner. We need something else.

Solution: download canon drivers from canon and install them. You have
to download - MG2400 series IJ Printer Driver Ver. 4.00 for Linux ,
debian package, and -MG2400 series ScanGear MP Ver. 2.20 for Linux
(debian Packagearchive). There are 2 manuals about these drivers
-ScanGear MP Ver. 2.20 for Linux (Operation guide) and -IJ Printer Driver Ver. 4.00 for Linux (Operation guide).

Once you have downloaded and extracted the .tar.gz files, read the
manuals. Read them carefully and follow the instructions. The problem
I had was that mint installed the printer by itself, automatically,
and I didn't eliminate it, so I had the same printer with 2 different
configurations, one with the canon driver and other with gutenprint
driver. With this configuration just the gutenprint driver works,
there is no scanner even if you install canon scanner driver.

When you install the canon printer driver with its installer
(./install.sh) first, before you can register the printer, mint has
installed it with its gutenprint driver, you only have the
notification. In the manuals, they say that "if a window that prompts
you to add a printer is automatically displayed when you connect the
machine, cancel the window by closing it.". Maybe you have the chance
with other distros, but mint doesn't ask. So you have to stop, go to
Menu-Administration-Printers and eliminate the printer mint installed
for you. Then you finish your canon printer driver installation. Turn
off the printer and install the scanner.

The same story if you install first the scanner, when you turn on the
machine, after installing the driver, mint installs the printer. Again
you have to go to Menu-Administration-Printers and eliminate the
printer mint installed for you. Then you can install the canon printer
driver, this time without interruptions.

Sorry, for repeating the above solution, but it was answered while i was typing in my response. I hate it when this happens as it makes me appear stupid, but I blame it on old age.

The answer is Yes.

Even if it doesn't work with Simple Scan on some systems, on others Simple Scan is working and/or sufficient.

In Ubuntu-14.04-based systems

If the drivers are installed but tools like Simple Scan and Xsane do not work, there is a separate scanning GUI tool from Canon called ScanGear that is automatically installed when installing the driver packages (scangearmp-common and scangearmp-mg2400series), and that is specifically intended for use as scanning application with the Pixma integrated scanner.

ScanGear can be run with the command scangearmp.

As seen in comments under questions here and here, there is also the idea of starting it within Gimp: File/Create/ScanGear MP

Also here.

But Gimp is not needed in order for ScanGear to work, people mention Gimp because (as in my case) ScanGear doesn't create its own desktop file in usr/share/applications, is absent in the menu, and by default cannot be accessed in launchers like Synapse, Dash, Kickoff. To remedy this and get easy access to the application, add a .desktop launcher for ScanGear. With gedittext editor:

sudo gedit /usr/share/applications/scan.desktop

and pasting this:

[Desktop Entry]

Categories=Graphics;Scanning;

Exec=scangearmp

Icon=scanner

Name=Scan

Type=Application

possibly making it executable

sudo chmod +x /usr/share/applications/scan.desktop

UPDATE on later systems:

The above was tested in ubuntu-14.04-based systems and in Manjaro 15.09 (with scangearmp-common).

As indicated in another answer, in ubuntu-15.10 Simple Scan should work.

In ubuntu 16.04-based systems, Simple Scan is enough and the drivers for the scanner are not needed.

Testing in Manjaro 16.10, the same thing: scangearmp-common is not needed and Simple Scan is enough.

It is supported. I have this printer connected to an Ubuntu 15.10 machine and it worked out of the box with simple-scan.

Well I have had to use Turboprint drivers for my new Canon TS8160. It works ok but needs paying for!

To get the scanner going I must use the terminal command scangearmp2

All I need for that is a GUI and I'm happy.
OS is Mint 18.3
