Looking for suggestions on how to get my scanner to scan a full page at full speed and not have to 'jog' 3 or 4 times.
Scanner is a Epson GT-30000. In slow speed it works, in full speed it "jogs" System: HP DL580G3 4 ea dual core 3GHz Zeon cpus Adaptec 29320 PCI-X 133 on a bus not shared with any other PCI device LSI ?? 320 PCI-X 133 on a bus not shared with any other PCI Device Fedora15 8 GB RAM DISK created from the above RAM Latest packages from Epkowa dll.conf consists of only epkowa Scanner Epson GT-30000 Connected VIA SCSI 68 pin (wide) Scanner ONLY RUNs at SCSI-2, 20 MB/s (40 MB/s transfer since wide I AM ASSUMING THIS, waiting to hear back from Epson) NOTE: Just confirmed from Epson, their online documentation lies in that it says SCSI-3 A full scan, 600 DPI color at full speed should take 8.058 Seconds and create a file approx 204 MBytes 0.79 mS per line, 10,200 lines 7,020 x 10,200 or 71,604.000 pixels 24 bits per pixels The key is 204.86 Megabytes in 8.058 Seconds which is 25.43 Megabytes per second. tests were done sending the output of scanimage to /dev/null. time scanimage --color-correction='No Correction' --mode=Color --resolution=600 --speed=yes > /dev/null some of the things I've done and tried installed the latest epkowa packages changed dll.conf to just epkowa (deleted everything other then epson2 which is commented out) increased /proc/scsi/sg/def_reserved_size to 1 Meg changed .../allow_dio to 1 (enable) increased SANE_SG_BUFFERSIZE to 1 Meg (and even higher) I've also downloaded the lastest sane, built it with gcc -march / tune = native, same resulits ========================================= Increasing the buffers to their max/1MB does help >From the sources can I increase the buffer(s) in sane ? I have 16 GB or RAM to play with Can I 'sniff' the SCSI bus to see if it is sane telling the scanner to wait or is it the scanner it self ? Other suggestions ? TIA .... -pete
