Sane is able to recognize the scanner using the X1100 driver. Whenever I try to scan something, the scanner makes a loud noise and the scanning head does not move. It appears that the head may be trying to go the wrong way. I am using Sane 1.0.17-3 from the Debian testing distribution. Here is the debug output from the driver.

IIRC, after power up, I just selected mono and started scanning. If you want, I can do this again and carefully record the single steps. Bye, Uwe Hi, For now, I do not it re-done. I am going to try to get an understanding of what was done in that log, and why. From what I have looked into so far, that program seems to have been less than a straight-forward design. I need to try some tests for undocumented register(s) to see if that changes results. This may take some time as well, so I do not expect results soon. I am hoping to just use this one log, and then see if that can get any kind of result. Thanks for producing that log. Gerald

Hi all, On 7/5/06, Gabriel Guerreiro gabriel.guerre...@gmail.com wrote: I have such a log. Sending in attachment. Sent it to stef last week. It's too long to send to the list. I could help with some tests too. I tried the patch you posted on the list, and made some scans. The image is unintelligible and dark. I reversed some changes in that patch: I don't need to hack the warmup. The gamma was being set twice. I tried to apply some of the configs of the hp2300, but with no results. Yes i know that patch is not giving any output. My observations for this scanner are 1)Warmup code is not passing test so scanner is not moving at all. So i need to modify warmup code so that scanner will start moving. 2)Also i did similar stuff of configuring HP2400 code like HP2300 wherever it applies but no results. Anyway will check log from you all. Regards, Parag.

Le mardi 4 juillet 2006 11:51, Thomas Mader a ?crit?: Hello, I have a HP Scanjet 2400c and would like to know if I can help somehow to speed up the development of the driver for this? Can I provide some information about it or something else? Hello, this topic has come a few time on the list. The way I see 2400 support added is to record usb activity under windows, decode it. Then modify the genesys backend accordingly. Test the changes, and compare debug output until it is close enough to windows behaviour. However, I think there is a 'roadmap': take the functions one after the other in the sequence they are used by the backend. For instance, it make no sense to directly jump to the final scan and trying to hack it, since it relies on values detected by previous functions. Here's the call graph for a preview: sane_open gl646_init gl646_init_regs sanei_genesys_create_slope_table sanei_genesys_create_gamma_table gl646_set_fe gl646_slow_back_home gl646_send_gamma_table gl646_set_powersaving sane_start gl646_save_power gl646_set_fe gl646_search_start_position gl646_setup_sensor sanei_genesys_exposure_time gl646_setup_steps sanei_genesys_create_slope_table gl646_send_slope_table gl646_set_fe gl646_begin_scan sanei_genesys_read_data_from_scanner this function generates a searh_position16.pnm and search_position.pnm which are pictures of the innings of the scanner. These should contain black and white areas that will be basis for postion detection. gl646_end_scan sanei_genesys_search_reference_point ... more to come ... I'm currently compelting this, but I think making gl646_search_start_position working will take enough time to let me finish. Some on these functions already test for HP2300. You can add tests and values for 2400 there. However, there are two points to take into account: - for the HP2300 I made the analog frontend work like the MD5345 one since I couldn't make it work like it is in usb logs. - motor slope creation should favor sanei_genesys_create_slope_table3() over the sanei_genesys_create_slope_table() currently used. I append the latest version of the scripts that I use for log decoding. The cmd.sh takes a decoded log and emits scanner status at each motor start (which is used as a 'commit'). It is usefull since you can take it's output to compare scanner internal state with the one from the backend log (output of gl646_bulk_write_register() ) right before gl646_begin_scan().
