Step 1: Download Force ASPI and install
Download from here http://radified.com/ASPI/forceaspi.htm
As you've read elsewhere by now, SCSI devices
aren't supported by Windows XP. Many forums dispensing advice point to Adaptec's website to download a layer of software called
ASPI (Advanced SCSI Programming Interface). In fact, Adaptec's ASPI layer works only on Adaptec's SCSI devices. Fortunately,
a good samaritan has modified Adaptec's ASPI to work on other SCSI devices, and provided it for free. You might want to use
a utility which is part of the download to clean up your system of other ASPI layer detritus before installing Force ASPI.
Step 2: Restart the computer.
Not strictly necessary, but I wanted to
be sure the registry is properly updated for the new software and the ASPI layer kicks in on startup. The ChkASPI utility
showed that it was.
Step 3: Install Adaptec USBXchange.
At this point, if your system previously
accepted a SCSI card interface, then I'm sure you'll try that before shelling out for a $30-$40 SCSI-to-USB cable converter.
Otherwise, try a cable converter, but make sure the driver is compatible with XP. I can vouch for the Adaptec's because I
use it -it works with XP and the Canon FS2710. You might want it get the USB2Xchange, only because your USB connection on
XP is more likely to be a USB2.0, not 1.1, standard. It's safer because the voltage delivered by a USB2.0 connection is
higher than USB1.1, so my system (USB 1.1device in a USB2.0 port) is powering the cable converter with a higher voltage than
it needs or uses. Sounds dangerous, but it's still working.
The USBXchange must be installed in the
1. Connect the SCSI end of the cable converter
to the scanner.
2. Turn on the scanner.
3. Turn on your PC, if not already on.
4. Then connect the USB end of the Cable
converter to the PCs USB connection.
5. When the new hardware found dialogue
shows up, insert the CD-ROM with the driver. The XP driver for the cable converter wasnt in my CD-ROM, so I downloaded it
from the Adaptec site prior to starting.
6. After the Adaptec cable converter has
been loaded, Restart the PC, and the Canon scanner will be detected (although it will be called something else by the PC),
starting another new hardware found dialogue.
Step 4: Select from list of device
drivers included in Windows XP, and choose UMAX 2200.
When XP searches for the scanner's driver,
I initially hit 'cancel' button until I exited the wizard, installed Canoscan software v.3.6.6 (apparently compatible with
XP), and after the software tried to initialise, I still got the message "No scanning device found". So I went through the
"new hardware found" wizard again, went to the option which offers a list of imaging device drivers included in Windows XP.
I select UMAX, and the model 2200. The driver for UMAX 2200 works fine with Canon FS2710. Now that's non-obvious, at least
I then used Vuescan software to operate
comments: Does using a UMAX driver
on the Canon FS2710 affect the scan quality? No, the colours of some orchids I scanned (top of this page) were spot on. I
suspect the driver only communicates instructions between the CPU and scanner, but interpreting scanned data to produce an
image is done by the scanning software, in this case Vuescan. Vuescan is lightyears ahead of the clumsy Canoscan, because
it does at least two useful things the Canoscan can't: (1) mutiple-pass scans, which reduces digital noise, (2) long exposure
passes, to extract detail from night and long exposures. - Andrew
