[sane-devel] Genesys HP ScanJet 2400
Hi It's been a while since anyone's posted anything on this scanner, so here goes: I've noticed that there is a section in the HEAD version (1.35) of the file genesys_devices.c in the experimental/genesys tree of CVS mentioning the HP ScanJet 2400c. My questions are: 1) Will this definition/driver work for the ScanJet 2400? 2) Can the developers tell me if it's actually usable to any point at the moment (and about any limitations in the current source). 3) is 2400c just an alias for 2400? Thank you Nick

Hello,
I have some questions again on HP2400 current development. How you
people are checking code? i mean i have also same code but neither scanimage
-L is recognising nor Xsane detects it.
then how can i check whatever features are implemented are correct or wrong?
only sane-find-scanner command is working fine but not xsane. How can i
calso check head movement?
regards,
Parag.

[sane-devel] Genesys HP scanjet 2400
Hello, sorry to have taken so long to answer, but I have little time and many things to do ... However, I believe it isn't helpful to modify the warmup that way. You have to set up the right register values instead. Also, you have to make sure that the scanner is using an area suitable for it, if the head is on a black area, no warmup will succeed. If I had enough time, here's how I'd do: - get a windows usb log of a colour preview, just after powering-up scanner - extract from it the values to put in genesys_devices regarding constants in Genesys_Frontend, Genesys_Sensor, Genesys_Gpo, Genesys_Motor. Current values aren't considered exact, testing is needed. - by running scanimage with full debug and comparing it's output with decode usb log, modify the genesys_gl646.c file to take 2400 specifics into account. Every places where is a xxx_HP2300 constant is a candidate. The HP2300 and MD5345 use a method to build slope tables which is superseded by the method used for GL841 parts. This newer method should be preferred. That involves using the newer exposure time comptuing function. I again attach the scripts I use to turn an usb log into something more suitable for developpement. I tested it on HP2400 logs I have. I think have all the elements to finish support for 2400 but I'm missing an essential thing: the scanner itself. Regards, Stef -- next part -- A non-text attachment was scrubbed...
