Hewlett-Packard ScanJet 3670c
Written on the chipset:
Also there is an Elite MT RAM chip:
EliteMT (100MHz) M1B416256A DZC1HF2GJ
Te Genesys backend may support that scanner when it's finished.
Same scanner as 3690?
Several people want to write a backend. See this thread on sane-devel for details.
Some Snoopy logs are available.
The Windows .inf file says, that it's the same driver for 3600 series and 2400 series?

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.
