[sane-devel] Microtek ScanMaker 636 at Advance Hostadapter

[Karsten Festag]

Hi Nicolas,
in the moment I have two suspicions:

1) I included a command which sets the timer for the automatic switch-off for 
the lamp. Maybe the firmware of your scanner doesn't support this command. To 
test this issue it is neccesary either to use an old sane version (1.0.4 or 
older) or (better) to compile from slightly modified sources. 

2) The failing command is the first that doesn't only read data from the 
scanner but sends data to the scanner. If that's the problem then it is 
probably scsi-related. A test for this might be to push the "toggle lamp" 
button in the advanced options in xsane. But you have to enable this button 
in the configuration file microtec2.conf (probably located in 
/usr/local/etc/sane.d). There has to be the line

 option toggle-lamp on

If pressing the button doesn't freeze the scanner then probably the above 
suspicion is right. If it also freezes - well then it might be a scsi issue 
but I would do also the first test.

If you like to compile a modified source that doesn't send the Timer command 
you have to remove the following lines from the function sane_start in 
microtek2.c:

 
        md->status.aloff |= 128;
        md->status.timeremain = 10;


Please tell me about your results!

Best wishes

Karsten
