Could you describe a little bit more what was the issue with grayscale<br>
scan on MX310 ?<br></blockquote><div><br>> BTW, B&W is currently not supported on this model, some more details<br>

<br>I was using gscan2pdf 0.9.29 to scan, under LinuxMint 8 (Helena). This is built on Ubuntu. gscan2pdf is the only Linux program I have found so far that comes anywhere close to the Windows PaperPort I was using before switching to Linux. When attempting to scan, this program opens a dialog box and looks for all scanning devices. It found the Cannon MX310, and presented options for scanning. <br>
<br>At first, it presented both Colour and Greyscale options. I am wanting to use the ASF to scan multiple documents into one PDF in B&W (aiming for smaller file sizes for storage and emailing) so I would choose "Greyscale" (as B&W was not an available option). Then I would use the "threshold" tool to optimise the result and then save. Although this would not give as small a file size as Paperport, at least it was acceptable.<br>
<br>After some months, when I opened the dialog to scan, the Greyscale option would not work properly. When selecting it, some different options (brightness was one I can remember) would become visible, and no matter what values I entered, there would be an error message to the effect that these options were not supported by the scanner. So I had to scan in colour, but the result even after using the threshold tool to optimise was unacceptably large file sizes. A 20-page contract was about 10 MB instead of 0.5MB. I resorted to waiting until I had a bunch of scanning to so, booting into Win Vista (yawn) and using PaperPort. Not a good solution, particularly when there was urgent work to be scanned and emailed!<br>
<br>About that time LinuxMint (ver 9, Isadora) became available, so I upgraded, hoping to fix the problem and get back to work. There was no difference, Greyscale attempts still produced the erroneous options.<br><br>So I contacted the author of gscan2pdf, who was extremely helpful, and gave me many tests to perform. The results showed that the problem was not with gscan2pdf, but with sane. I am such a newbie I had not really twigged that the one program was accessing the other, but I am learning fast! Finally, it was suggested that I join this list and put forward the problem, as the issue seemed to be with the way sane interacted with this particular scanner. I joined.<br>
<br>But before actually asking the question I attempted one of the suggestions of the gscan2pdf author, which was to upgrade sane. Via LinuxMint, the only way I have been installing and upgrading is via the Package Manager. It seems often to be a few versions behind the latest stable release. I understand the reasons for that, but I wanted to press on and get the cutting-edge (but stable) version anyway. I downloaded this file <a href="https://alioth.debian.org/frs/download.php/3258/sane-backends-1.0.21.tar.gz">https://alioth.debian.org/frs/download.php/3258/sane-backends-1.0.21.tar.gz</a><br>
<br>Opening the instructions contained in that package, I found this: "the shell commands `./configure; make; make install' should configure, build, and install this package."<br><br>I also found this...<br>
<br><div style="margin-left: 40px;">The simplest way to compile this package is:<br><br> 1. `cd' to the directory containing the package's source code and type<br> `./configure' to configure the package for your system.<br>
<br> Running `configure' might take a while. While running, it prints<br> some messages telling which features it is checking for.<br><br> 2. Type `make' to compile the package.<br><br> 3. Optionally, type `make check' to run any self-tests that come with<br>
the package.<br><br> 4. Type `make install' to install the programs and any data files and<br> documentation.<br></div><br><br>So I opened Terminal and played around with those commands until it seemed to do something. Took a long time and wrote a lot of (to me) arcane stuff to Terminal, but eventually it stopped and claimed to have done the job.<br>
<br>However, from that moment, the machine has refused to access this or any other scanner, claiming 'no device found'. (I have two other flatbed scanners, and I tried them, but no device found)<br><br>I have been watching and reading this list for a month or so, and decided the time had come to ask my question. (Somehow I used the wrong email address, but thankfully the moderators allowed it through anyway)<br>
<br>BTW this is a dual-core Toshiba Satellite. I have an Asus eeePC netbook also dual-booting LinuxMint, and I have been using that to scan in the meantime. It's slower of course, but it works.<br><br>Re the B&W issue: I had sort of concluded that maybe the Cannon MX310 doesn't natively scan in B&W, and that being able to select that with Win PaperPort was because the program was doing a background conversion. The later gscan2pdf version has the ability to optimise to B&W, but as I have had such "thundering success" (!) with installing programs in Linux I have not been able to install it. (Yet: but I hope John MacGill's link to <a href="https://help.ubuntu.com/community/CompileSaneFromSource" target="_blank">https://help.ubuntu.com/community/CompileSaneFromSource</a> will put me right there - thanks John!)<br>
<br>Also, while writing this email I accessed LinuxMint to make sure Isadora-9 was the latest, and I see the new built-on-Debian version has been released. I have been waiting for this, because it's a bit of a pain reinstalling every 6 months to keep up with current releases (which is the way the built-on-Ubuntu versions had worked)<br>
<br>So in the next couple of weeks I will find the time to upgrade to this entirely new version, and no doubt that will fix the "can't find any scanner" issue. A bit of a blunt force approach, but I intend to upgrade anyway.<br>
<br>However, if one of you knowledgable ones, having bored yourself all the way through to this point, still wants to assist, I would appreciate some insight on how to get sane working again so I can scan from the faster machine, and also increase my understanding of how these things work for future use.<br>
<br>Cheers at last!<br><br>Lance<br>(Mr Fair Go)<br></div><div><br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
BTW, B&W is currently not supported on this model, some more details<br>
about how you were proceeding would be useful to step further.<br>
