Simple scan can not detect scanner

The "simple scan" can not find the scanner device:


But according to the "sane-find-scanner", there is found "SB scanner (vendor=0x04a9 [Canon], product=0x1855 [E4200 series]) at libusb:001:010".
Do you think problem is permissions to this usb-scanner so that simple scan can not access this scanner?

Also in the openoffice image import, it can not find the scanner either.

Also the "scanimage" can not find the scanner, even the "sane-find-scanner" finds it:

jari@ENVY-17:~/Sirius$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).


Not sure if below settings could be wrong somehow:

I have the exact same issue - what is annoying Simple Scan (new name is Document Scanner in later versions of Ubuntu and Fedora Workstation - it works in the latter).

I'm afraid you need to use this package for your Canon Scanner:



Extract using Ark then go to the 64-bit folder and install the .deb file using Software or install Gdebi Package installer to install that way. Then to launch you open terminal and enter:

Code:

scangearmp2

It is very basic - sadly Canon apparently had the same interface for earlier version of scangear for linux as for Windows users - why they ditched it I will never know! You can create a desktop shortcut:



Alternatively you could shell out for this:

https://www.hamrick.com/

but check that your scanner is supported before purchasing if you decide to go down this route - there is usually a demo package which leaves a watermark on scanned docs/images.

I have that already, and that seems to work quite well, but it does not allow scanning multiple pages in same pdf-file.
Earlier with different canon scanner with Fedora linux the sane-tools seemed to work.

Also the Open Office import function can not use this scanner or I don't know how to make it work in open office scan image import:

Here was no kind of scanner found.

Was that the case in Fedora too? I must say that Fedora is bleak compared to other distributions in terms of software installation (see my post in Other OS discussion thread about how rubbish Fedora 31 Workstation is - and it hardly comes with any decent software, very minimalist compared to Zorin OS and others out there.

Just tried Ubuntu 20.04 in a VM inside of FerenOS and it picks up the Canon Scanner in Document Scanner straight off. It falls over in respect of LibreOffice - LibreOffice still has the help file bug - it fails to connect to the internet help guide!
Hopefully, when Zorin gets upgraded to one based on 20.04 we will all benefit. I also hope the Zorin team will revert to the live screen boot that was used in 12.04 and earlier - it can iron out a lot of issues if you have the option to disable certain elements at the start like acpi=off etc. Dropping stuff that is known to work well is a big mistake!

The "printer" of the printer-scanner is there, but scan-function is missing.
Should there be setup for scanner also? (This looks like printer only setup)


It can print a test page, but it can not do anything with the scanner function nor scan a test page:

Go back to my last post on this issue - you say you have scangearmp2 - you install the package like I gave here: viewtopic.php?f=5&t=15801#p71927

and then enter scangearmp2 - in a terminal.

Yes. I know the scangearmP2, but this is question about the setup menus.

Well just remember that Linux isn't Windows and vice-versa.

This question is not about windows and I don't know what is that about.
I hope it can work on any OS.
And also it seems it can not find the CANON as a network printer...

Also network setup seem to be limited, not only the scanning (that seems completely closed by linux, excluding the Canons own scanning program).
There is a lot of player here, like the HP-ENVY, Linux, Sonicwall SOHO, PLDT modem/router and the CanonE4200. So it is really hard to tell
what is causing the problem. Most likely some setup issue or software incompatibility issue.

In case of Windows10 similar issues is displayed as:

What I was trying to point out in my last post is that the Settings interface is nothing like Windows 'Devices and Printers' - you won't get a Scanner listed anywhere in Settings. As I have pointed out elsewhere, Ubuntu 20.04 picks up the Scanner of my Canon TS8151 immediately using the new name of Simple Scan (Document Scanner), so eventually we should be able to access our scanners that way in a more pleasing interface than scangearmp2!

As for the printer element - have you downloaded this?:



Download and extract the zip file above using Ark, then go to Packages and install the 64-bit .deb package then open a terminal and enter:

Code:

xhost +si:localuser:root

this gives you temporary root privileges as sudo no longer works on its own which I only found out myself and had to search internet for solution!

Code:

sudo system-config-printer

to get the 'Add printer' interface up.
