yes. the fujitsu backend has been nearly completely rewritten between sane 
1.0.17 and .18. Many of the options provided by the backend may have 
changed names or take a different range of options. if your scripts are 
coded to look for certain option names, they will no longer work.

what do you mean 'NOT accepted', do you get an error?

what messages do they provide? my copy says:

     -x 0..224.846mm (in steps of 0.0211639) [215.872]
         Width of scan-area.
     -y 0..863.489mm (in steps of 0.0211639) [279.364]
         Height of scan-area.
     --pagewidth 0..224.846mm (in steps of 0.0211639) [215.872]
         Must be set properly to align scanning window
     --pageheight 0..863.489mm (in steps of 0.0211639) [279.364]
         Must be set properly to eject pages

-l and -x are not the same as --pagewidth. the last tells the scanner the 
size of the paper so it can decide where the left margin on the adf 
is located. the other two set the location of the area that will be 
scanned. note that the pagewidth must be larger than the location you are 
trying to scan, or you will likely get an error.

this is common to all multi-word options accessed by scanimage, and not 
fujitsu specific. the output that you see is generated by scanimage. 
perhaps scanimage could check for whitespace inside a string arg, and put 
quotes around it before display.

maybe escape the quotes with a \ when you build your SCAN_OPTS variable?
this is really a bash question, not a sane question.
