+ If anything is wrong or missing on this page please file a bug report + or use the the + form for adding an unsupported device. +
++ If you own an unsupported scanner, please send as much information as + possible. Especially the output of sane-find-scanner -v -v + and/or cat /proc/scsi/scsi (for SCSI scanners) or cat + /proc/bus/usb/devices (for USB scanners) can help. If you dare to + open the scanner, have a look at the text that's printed on the + chips. That may help to identify the chipset. If you know that the + scanner is similar to another one (e.g. supported by the same Windows + driver), please also mention this fact. +
+ ++ Are you a manufacturer or vendor of scanners and one of your scanners is + not supported by SANE yet? In this case please have a look at our information for manufacturers. +
