I have a question about a scanner of mine. It is a ScanPlus III 300
scanner, and according to the online manual, it has a SCSI interface
with a SCSI card included, but looking at the scanner, it appears to
have a parallel port interface(right number of pins), including a
connector with a printer symbol, presumably for sharing the parallel
port. Can anyone explain this seeming contradiction?
Here is the link to the manual.

The PDF is almost unreadable (I took a brief look), and I don't know that
scanner, but a 25 pin SCSI port and standard parallel port look identical
(and both scsi cable and printer cable will fit either (but one will not
work in the other, of course).
Don't know your scanner, but my old (and reliable) Agfa Snapscan 310 uses a
"loop-thru" parallel port which then goes on to my printer. However in Device
Manager (Win98SE) , there is an entry for Agfa EPPSCSI Miniport driver, under
the SCSI Controllers section. "Refreshing" this entry helps to wake my scanner
connection from slumber.
I couldn't find a usable picture in the manual, but I'm quite sure it
is a SCSI connector.
There are numerous SCSI connectors.
For old devices and this seems quite old there are 2 possibilities.
One is a 25 pin D connector. This was mostly used on Apple Macs.
The other was a 50 pin Centronics connector. This looks just like the
printer Centronics connector but the printer connector is only 36 pin
and therefore narrower.
Use facotry default number. Not 0 or 7.

The following information applies to PCs only.
Now the bad part I got from a quick scan of the manual, the orignial SCSI
card was a 8 or 16 bit ISA card, that will not work in any computer made in
the last 3 to 5 years. Computers today do not have ISA slots any more. But,
you can get a PCI SCSI card that will work. I know of at least two cards
that may work.
1. Adaptec 2906 $65 USD + shipping. You may find them cheaper on
2. Benq Scsi Card. $19 USD + shipping.
Scroll down to see it. There is also a Scsi cable, but it is only 3 ft.
long, I think it is too short.
Belkin makes a good 6 ft. scsi cable. The Belkin Number is "F2A047-06" it is
labeled as a IEEE 1284 A-A Switchbox cable DB25 Male/Male Parallel.
Get the Scsi driver software for the Benq Card at:
Download any of the Acard SCSI Driver links.
I hope you have the scanner driver software!
