Edit debian/control and remove tetex-* from the Build-Depends line. Then edit doc/Makefile.in in the SANE sources, locate the STANDARD = sane.ps line and make it read STANDARD = (ie remove sane.ps) instead.

This report is written with regard to the HP ScanJet 7400C scanner (avision driver).

Bug#443254: sane: Scanner heads goes too far, bangs against frame (HP ScanJet 7400C)
Hi, I can not reproduce the crashing head on my side, however I know about the stripes, those color stripes are a regression from calibration changes in the avision backend. I so far had no time to track them down, However with some C knowledge and some trial'n error or SVN change review it should be possible to track it down in some hours. The calibration worked on the 7400 when I implemented 74xx support like 4 years ago or so :-) Can the reporter try my latest development code from: http://svn.exactcode.de/sane-avision/trunk/backend/ to see if the crashing head issue disappears?

Bug#443254: sane: Scanner heads goes too far, bangs against frame (HP ScanJet 7400C)
Hello, | I can not reproduce the crashing head on my side, Actually, we discussed this same issue about three years ago. Before buying my HP 7400c scanner, I contacted you (not through Debian) to know if the driver could be considered satisfying for this hardware. You said yes, it worked very well, except that one needed to be ready to unplug the scanner at a moment's notice precisely because sometimes the head goes too far. I took my chances, bought the scanner, banged the head several times, contacted you again and you said it might be fixed in the latest snapshot, which would not go into Debian for quite some time. That's when I bought Vuescan and stopped using Sane, hoping to come back to it later. Now it is quite later and the problem is still the very same. I'm not saying I don't appreciate the work you've already done, I do, but this bug is really bad and renders Sane totally unusable in my opinion for this hardware. God knows I scan a lot of documents and would really prefer my Sane-based scripts to Vuescan's GUI and poor quality. | Can the reporter try my latest development code from: | http://svn.exactcode.de/sane-avision/trunk/backend/ | to see if the crashing head issue disappears? I'm not familiar with the procedure, but here is what I did: * downloaded the sources from sane-backends-1.0.18; * downloaded the files from the URL and copied them into the sources; * dpkg-buildpackage -us -uc -rfakeroot This is what I get: dpkg-checkbuilddeps: Unmet build dependencies: debhelper (= 5.0.0) dpatch libgphoto2-2-dev libltdl3-dev libjpeg62-dev libtiff4-dev libusb-dev (= 2:0.1.10a-9) libieee1284-3-dev (= 0.2.3-1) gettext tetex-bin tetex-extra autotools-dev pkg-config chrpath I could install all of these packages except for tetex-bin and tetex-extra.
