Warning: the 'niash' backend for HP3300C, HP3400C, HP4300C and Agfa Snapscan Touch scanners has been accepted into SANE, the info on this page is possibly outdated!


See also the HP3300 backend page on sourceforge for downloads, a forum, CVS archive, etc. .
Here's the README.html for getting the testtool and the SANE backend to run on your scanner.


This page describes my experiences with the hp scanjet 3300C scanner, which is not supported under Linux (yet). This information is meant to eventually lead to a SANE backend for all scanners using a NIASH chip, but work will be concentrated on the HP3300C (which I have personally).

The NIASH chip is found in the following scanners (bold = my scanner):

Manufacturer Model ASIC Analog front-end USB ID
Hewlett-Packard Scanjet 3300c NIASH00012
Agfa Snapscan Touch NIASH00014 ESIC ES8100QA 06BD-0100
Hewlett-Packard Scanjet 3400c NIASH00019 WM8143-12 03F0-0405
Hewlett-Packard Scanjet 4300c NIASH00019 ESIC ES8100QA 03F0-0305

The following scanners are not supported but they are mentioned because people ask a lot about them.

The HP3300C is an USB color scanner. It is externally powered. On the front is has two buttons that can trigger the scanner software to make either a scan or a copy. It has a horizontal resolution of 600 DPI (5300 pixels) and a vertical resolution of 1200 lines per inch.

It has the following chipset:

Inspection of USB traffic

USB snoopy is used for USB traffic analysis under Windows. It shows the type of messages going over the USB and their contents. The large amount of data coming past USB snoopy can sometimes cause the USB log to miss some data, so I made a slightly modified version for v0.12 and modified version for v0.13 that does not show the contents of the USB bulk transfers.
