[sane-devel] Replaced my Canon MF240 with a MF260

[John Rodriguez]

Hi,

I just purchased a Canon imageClass MF264dw Multifunction Laser Printer 
with scanner.  Printing works but scanning does not. I am using the 
printer / scanner over my local area wifi, my OS is Linux (Debian 
Bullseye).

scanimage -L reports "No scanners were identified..."


The relevant sane-find-scanner output is:

found USB scanner (vendor=0x0a5c [Broadcom Corp], product=0x21e8 
[BCM20702A0]) at libusb:002:004
   # Your USB scanner was (probably) detected. It may or may not be 
supported by
   # SANE. Try scanimage -L and read the backend's manpage.


The content of the _scanner._tcp service entry in mDNS/DNS-SD suggests 
that the proper protocols are supported:

Service data for service 'Canon MF260' of type '_scanner._tcp' in domain 
'local' on 3.0:
     Host Canon58871c.local (10.0.1.2), port 8610, TXT data: 
['scannerAvailable=1', 'MDL=MF260 Series', 'MFG=Canon', 
'UUID=9c32ce58871c', 'ty=Canon MF260 Series', 
'adminurl=http://Canon58871c.local/airprint.html', 'note=', 'txtvers=1']


Looking at the man page for "Backend: pixma (0.27.0)" that is currently 
on the SANE website, the model is listed under the section " The  
following  models  may use the same Pixma protocol as those listed above..."

However, I am not running the latest backend.  Running apt-cache policy 
sane-utils yields:

sane-utils:
   Installed: 1.0.27-3.2+b1
   Candidate: 1.0.27-3.2+b1
   Version table:
  *** 1.0.27-3.2+b1 500
         500 http://deb.debian.org/debian bullseye/main amd64 Packages
         100 /var/lib/dpkg/status

You can also see that I'm running Debian Bullseye (testing) and that my 
version is the latest available in the repo. However my local man page 
is dated 20 May 2017 and my model is not mentioned.

On the SANE website (http://sane-project.org/sane-backends.html#S-CANON) 
I see
  i-SENSYS MF260 Series     USB Ethernet WiFi     0x04a9/0x27f4 Untested 
     Testers needed! Duplex only for MF269.

Is there a way that I can enable the model in my current backend? 
Alternatively, is there a way to install a newer backend without 
breaking my system or installing from source code.  I previously had a 
MF240 and that worked fine.  This new model(MF260) seems almost 
identical physically.  I bet the MF240 driver (pixma) will work with it.

Any help getting the scanner to work would be greatly appreciated.

Thanks.
