[sane-devel] Epson 2480 Transparency Unit

2005-08-07 Thread Ken Ramey
What version of code is necessary for this to work? My system has snapscan-1.0.15 and libusb 0.1.8. When I try to scan a slide or negative at anything over 300 dpi, it has multiple verticle color lines through it. The higher the resolution, the more lines there are. Reading the various mailing

Still trying to resolve the issues with the 2480 scanner when using the transparency unit. Using gimp and the Acquire Image... with xsane also results in messed up preview area. The scans are still not usable, but getting closer. From Gimp, the number of color bands is reduced by half. I'm not

After several days of working on this problem, it seems obvious that the sane package will not support the transparency unit on the Epson 2480. After working for two days with the latest sane-backends package (1.0.16) and having more problems than with the older version, I have dropped back down

Reinald; I was hoping to do an actual compare of the contents of the files. If we find that the files have different instructions in them, that would be a start. BTW; is your 2480 working (including transparencies) or not? What would be most useful would be to compare the firmware from a

These recent entries about embedded file version information are intriguing. Could it be as simple as downloading a more recent version of the frimware from Epson? I am away from my computer for the next day and a half - visiting my sister and her husband - but I will take a look at my firmware

Reinald; I don't mean to be insulting, but did you remember to change snapscan.conf to point to the newer version of the firmware file? Also, depending on your particular installation, the firmware (along with the .conf file) may need to be in either /usr/local/etc/sane.d or /etc/sane.d.

Hello; I have been working all weekend on this problem. At the beginning, my new scanner wasn't even recognized by Fedora. Now, it is recognized but I am unable to acquire any images. In all cases, the scanner seems to perform a full scan, but no image appears. In the cases of iscan and xsane,
