Check the mode the port is set to in the BIOPS. The scanner might need one of the "new" modes, ECP or EPP, to work correctly. Or it might want the traditional mode. :D

(SCSI 1 cards for the PC often used 25 pin DB connectors like the PC printer and serial ports port --- because it took less space than the SCSI1 connector. Apple used it as standard at the computer end. There was one other manufacturer who used a mutually assured destruction different SCSI pinout on the 25 pin connectors. SCSI devices often didn't survive being connected to serial ports ... -12 volts would get them even if +12 didn't. SCSI uses 5 V so should be reasonably safe on parallel port.)

478793 2006-08-17 10:47:00 Very sorry for the trouble I have caused on this one.

The 2 pcs' are Pentium 1 and about the same age, the only difference is the number of pins on the male and female connections!!!.

25 for scanner and 26 for the other computer.

Thanks again to all who helped out on this one.

478794 2006-08-18 00:31:00 Now that it's morning and the brain is working a bit better. have taken the parallel cable out of pc and there are only 25 holes, so the PR5 PCI Main Board manual is wrong.

Have been through both BIOS menus:

Digital Venturis 5100 P1, the machine able to work the scanner.

Phoenix BIOS 1985-1995
No mention of Parallel or Serial Ports in the menu.

General machine, the macchine we want to connect scanner to.

ROM PCI/ISA BIOS (2A59GA1A)
CMOS Setup Utility
Award Software, Inc

Shows: PCI & Onboard I/O Setup
Onboard Serial Port 1 Auto
Onboard Serial Port 2 Disabled

* Onboard Parallel Port 378/IRQ7
-Parallel Port Mode Normal

*Has a "Disabled" option

Would replacing 378/IRQ7 with the Disabled option affect the computer from operating?.
Everything in the Device Manager on both machines is identical, except for the Resource type which are reversed:

Interupt 07
Input/Output Range 0378.037F

Thanks again,

Lurking.

478795 2006-08-18 01:10:00 Your 25 pin plug is a scsi plug. Get a scsi card to put inside your computer and plug the scanner into that. I use to run a Iomega Zip drive a few years ago and it needed a scsi card to run off. A PCI scsi card cost about $70.

478796 2006-08-18 01:45:00 But Trev, a scanner which is made to be daisychained with a printer (as this on is) doesn't have a SCSI connector. :D

Lurking, go back into the BIOS and try to change that printer mode from "Normal". You might have EPP or ECP or EPP/ECP as options. Try any or all modes available until you find one which does work. :cool:

478797 2006-08-18 05:03:00 Right forget the scsi stuff, this scanner definitely connects to a parallel port.

download.canon.com.au

Obviously the port must not be disabled in BIOS or it definitely wont work :)

Pages 39/41 of the manual discuss the port settings, and also says run a Canon utility CD in case of problems.

It is always possible that either the scanner, or the parallel port (or the cable) is stuffed.

478798 2006-08-18 09:43:00 A 350 is very different to a 640. It would be nice to know what we are dealing with.

I think Terrey is right on the money.

Lurking appears to have a serial port like Com 1 or 2 one of which may be disabled so the modem works. Parallel ports are a different animal. COM1 or COM2 could also have 25 pins or 9 for that matter.

I can't see it from here.

478799 2006-08-18 20:51:00 I have one of those scanners and you need to set the Lpt port mode to ecp in the BIOS and its certainly is a parallel port scanner. beama (111)
478800 2006-08-18 21:03:00 Thanks again folks.

Sweep, this post is starting to buildup now, but as stated in my original post, the machine is a Canon N340P/N640P.

Yes the machine is a daisychain and a 25 pin to 25 pin.

Changed the BIOS setting to Disabled, this now brings up the scanner screen, press Preview and the same statement appears, Attach the Scanner, but it doesn't locup the machine.

The Main Board is a PRS PCI if that's any help and the only extra items put on have been a Dual USB card and a "don't laugh" and 5.25in floppy drive, needed for an old Works collection of stored data.

Lets hope our helpful pressf1 team can solve this one.

478801 2006-08-18 23:29:00 Graham L, thanks for the BIOS settings.

Have these settings for parallel port:

Disabled
3BC/IRQ7
378/IRQ7 which was the setting that it was set at for the old printer.
278/IRQ5
Disabled

Those are the only readings PgUp and PgDown showed.
