HP3300c SANE backend is a Linux SANE backend for the HP3300c USB color scanner.
Support for other scanners with very similar chipsets, like the HP3400c, HP4300c and the Agfa Touch is also planned.
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:
- NIPEDC0804, two rows of 20 pins along bottom and top edge. It has a 12.000 MHz crystal mounted close to it. This chip was mentioned as an 'interface' chip on an electronics web page. The pinout of this chip is very similar to the Genesys Logic GL640USB chip (datasheet available).
- KM2Q65R, T224162B-28J, '100 Mhz', a 256k x 16 EDO DRAM chip from Taiwan - Memory Technology (TMTech) (datasheet available). The HP3400C has a EliteMT 100 MHz M11B416256A, also a 256k x 16 DRAM chip.
- ESIC ES8100QA, pins on all four sides, the 'analog-front-end'. Also the Wolfson Micro WM8143 (datasheet available) has been reported. These two chips seem to be completely compatible.
- NIASH00014, pins on all four sides, 100 in total. This is the main controller IC. It has a 20.000 MHz crystal on pins 61 and 62. Two HP3400c scanners have been reported to contain a NIASH00019 chip.
