Doesn't seem to do it. Adding "option scsi-buffer-size-max 32767" to
/etc/sane.d/umax.conf gives the following result:
# scanimage -v -y 165 -x 120 --resolution 300 > b
scanimage: sane_start: Out of memory
scanimage: read 0 bytes in total
Without setting the buffer size, here is what I get:
# scanimage -v -y 165 -x 120 --resolution 300 > b
scanimage: scanning image of size 1417x1948 pixels at 24 bits/pixel
scanimage: acquiring RGB frame
scanimage: min/max graylevel value = 255/0
scanimage: read 0 bytes in total
# ls -l b
-rw-r--r-- 1 root root 37 Mar 14 11:10 b
#
However, when the mode is specified as LineArt, it appears to work:
# scanimage -v -y 165 -x 120 --resolution 300 --mode LineArt > b
scanimage: scanning image of size 1416x1948 pixels at 1 bits/pixel
scanimage: acquiring gray frame
scanimage: read 344796 bytes in total
# ls -l b
-rw-r--r-- 1 root root 344829 Mar 14 11:17 b
#
When set to grayscale, it still bombs out but not as quickly as with a
color scan:
# scanimage -v -y 165 -x 120 --resolution 300 --mode Gray > c
scanimage: scanning image of size 1417x1948 pixels at 8 bits/pixel
scanimage: acquiring gray frame
scanimage: min/max graylevel value = 13/255
scanimage: read 56680 bytes in total
# ls -l c
-rw-r--r-- 1 root root 56717 Mar 14 11:18 c

The SCSI controller is a BusLogic BT-958 that has worked in the past in
conjunction with this scanner. The only conceivable change is that SANE
was upgraded.
