I have just installed the latest Ubuntu Linux distribution on my computer. I did so, because I was unable to install the drivers for the scanner component of my Canon PIXMA TR8520 office printer, scanner, copier and fax machine desktop combo device on my computer when I was running Zorin OS; a Ubuntu-based Linux operating system. At the time that I had Zorin OS installed, I posted my concern in this Canon Community Support forum; to see if anyone could help me to install the scanner driver for my multifunction Canon PIXMA TR8520 office device on my computer; and I was told that Canon unfortunatelly did not offer any support for installing the Linux drivers that it provides onto Zorin OS regardless of the fact that Zorin OS is a Ubuntu based Linux distribution. In fact, they only offer support for installing these drivers onto either Ubuntu Linux or Fedora Linux. So, I installed Ubuntu Linux in place of Zorin OS, using the partition that Zorin OS occupied in my system.

Then, I went to the support page for my Canon multifunction device and downloaded the manual for installing the ScanGear MP driver for the scanner component of my device on Ubuntu Linux. That manual is called "ScanGear MP for Linux (Operation guide)" and is available at the following URLs as a compressed file with the .TAR.GZ file extension:

Then, I proceeded to follow the instructions that the manual provided as closely as possible, for installing this driver onto my computer. I started by downloading the Debian package of the driver; which is the scangearmp2-3.50-1-deb.tar.gz archive file; from the following URLs:

I downloaded the archived file to my Downloads folders in Ubuntu. Then, continuing to follow the instructions to install this printer's driver for its scanner component, I openned a Linux terminal. I made sure that my Canon Printer and Scanner device was turned off and connected it to my laptop computer using a USB wire and the USB port. Then, I got to my Downloads folder, to where I had downloaded the driver for installation, by typing the following into the Linux terminal, then pressing the Enter (or Return) key:

cd Downloads

Then, I unarchived the scangearmp2-3.50-1-deb.tar.gz by typing the following command, then pressing Enter again:

tar zxvf scangearmp2-3.50-1-deb.tar.gz

Then, I openned the the scangearmp2-3.50-1-deb archive by typing the following command into the terminal, then pressing Enter again:

cd scangearmp2-3.50-1-deb

Then, I finished installing the scan driver by typing the following command, pressing Enter, then typing in the same password that I used to login to my Ubuntu account at the prompt that followed:

sudo ./install.sh

Once this driver was installed, I tested it to see if it was working by attempting to scan an image. I began by turning on my Canon PIXMA TR9520 multifunction printer and scanner device, then typing the following command in the terminal, followed by a press of the Enter key, in order to open Scan Gear MP:

scangearmp2

Then, in the "Select Scanner" window panel and prompt that opened up, a message appeared saying that no scanner was found connected to my device. The exact message of this alert was "No scanners detected." To attempt to see if I could get this driver to work even though it did not seem to want to do that, I clicked on the button that said "Update Scanner List." Then, another window openned that said "Searching for scanners." Then, a message popped-up on top of my screen saying "Scan Gear is ready." Then, another warning came up in a different window that said "Cannot find available scanners. Cable may be disconnected or scanner may be turned off. Check the scanner status then try again."

So, I double checked to make sure that my Canon PIXMA TR8520 printer and scanner device was on and properly connect to my laptop using the USB cable and the USB port; and it was. Then, I unplugged the USB cord from my USB drive, plugged it back in and tried clicking the the button called "Update Scanner List" again, yet to no avail. Once again, another window openned that said "Searching for scanners." Then, a message popped-up on top of my screen saying "Scan Gear is ready." Then, another warning came up in a different window that said "Cannot find available scanners. Cable may be disconnected or scanner may be turned off. Check the scanner status then try again."

So, I tried uninstalling the scanner driver and attempting to install it using the second method outlined in the manual for installing this driver onto the Ubuntu Linux Operating System. To begin this process, I closed out of Scan Gear by clicking the X button on the right-hand corner of its window. Then, I exitted the directories that I had gotten into by entering the following command into the terminal, followed by a press of the Enter key, to go back down the directory tree:

cd ..

Then, I entered the following command again and pressed Enter again:

cd ..

Then, I proceeded to enter the following commands in the terminal to uninstall the Scan Gear driver, press the Enter key once more, and then type-in my password at the prompt the followed:

sudo scangearmp2-pkgconfig.sh --uninstall

Once it was done uninstalling, I attempted to install Scan Gear again; only to do so by specifying the package this time around. So, I turned off my Canon PIXMA 8520 device, while leaving the USB cable connecting it to my computer. Then, I typed the following command in the terminal, followed by a press of the Enter key:

cd Downloads/scangearmp2-3.50-1-deb/packages

This got me to the packages directory inside of the scangearmp2-3.50-1-deb folder, within my Downloads folder from the terminal. Then, I typed the following command at the terminal to finish this process of installing this driver for a 64 bit computer, followed by typing my password at the prompt once again:

sudo dpkg -iG scangearmp2_3.50-1_amd64.deb

Then, I tried testing my installation once again, to see if it worked this time. I did so by typing the following command in the Linux termina, in order to open Scan Gear MP, followed by pressing the Enter key:

- scangearmp2

Then, in the Select Scanner window panel and prompt that opened up again, a message appeared once more saying that no scanner was found connected to my device. The exact message of this alert was "No scanners detected" again. To attempt to see if I could get this driver to work another time, even though it had just failed to do so once more, I clicked on the button that said "Update Scanner List" again. Then, another window openned that said "Searching for scanners" once again. Then, a message popped-up on top of my screen saying "Scan Gear is ready" again. Then, once again, another warning came up in a different window that said "Cannot find available scanners. Cable may be disconnected or scanner may be turned off. Check the scanner status then try again."

So, I double checked to make sure that my Canon PIXMA TR8520 printer and scanner device was on and properly connect to my laptop using the USB cable and the USB port once again; and, again, it was. Then, I unplugged the USB cord from my USB drive, once again, plugged it back in again. Then, I tried clicking the the button called "Update Scanner List" again, yet to no avail. Once again, another window openned that said "Searching for scanners." Then, a message popped-up on top of my screen saying "Scan Gear is ready." Then, another warning came up in a different window that said "Cannot find available scanners. Cable may be disconnected or scanner may be turned off. Check the scanner status then try again."

So, installing the driver for my Canon PIXMA TR8520 in my official Ubuntu distribution of the Linux Operating System failed using both installation methods outlined in the manual for "ScanGear MP installation for Linux," like it did when I previously tried to install this driver onto Zorin OS. Could anyone help me to fix this problem so that I can get my Canon PIXMA TR8520 multifunction device's scanner component to work with my Ubuntu Linux Operating System?

I would really appreciate it!

Could it be that my Ubuntu driver package is missing dependencies that it needs to run properly? If so, does anyone know what depencies it could be missing? I have made sure that the "camberra-gtk-module" is installed in my system by following the guidelines in the following Ubuntu forum:

https://askubuntu.com/questions/342202/failed-to-load-module-canberra-gtk-module-but-already-install...

Then, I followed all of the directions outlined in my previous post to attempt to install the Canon PIXMA TR8520 driver for Ubuntu Linux Operating System once again, only to find that I got the same exact results.

Hey everyone!

To sum-up my problem, I have a multi-function Canon PIXMA TR8520 device which can both print and scan. However, I cannot get it to scan on Ubuntu: only to print.

Could anyone help me, please?

Sincerely,

Nataly Mota

I hope the engineer who programmed the drivers reads this and realizes how badly written/tested programs affects users out there.
