Hi Allan,
I scan paper docs and convert to pdf,
some times there are many pages,
batch mode will be quicker than single page mode,
there is enough time when head is going back to change page,
but the most important reason is,
i trying to avoid scaner calibration before every scan
(about 20sec every time)
i wrote about this bug in gt68xx earlier...

sounds not good for me we dont have a resident expert on the gt68xx :(
