Hewlett-Packard Scanjet 4570c
Similar to a GL841. Not yet confirmed, however. sane-find-scanner seems to be able to communicate with the chipset in GL841 mode but it doesn't get the same value it writes to the register back when reading.

Some discussion about the protocol can be found in the sane-devel mailinglist archive.
Portrait scanner with TA, similar to 4500C. Same as 5550C, but without ADF. The manual says: 4500c and 5500c series.
For more information, see bug report #301110.
"According to manual similar to 4500c and 5500c series scanners. It comes with a transparent materials adaptor (TMA). [...] The TMA is an external device which can be unplugged. Windows XP refers to it as HP ScanJet 4570c/5500c Windows uses usbscn.sys hpgtbb.dll hpgwiand.dll hpsjvset.dll."

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.
