Vista Not Communicating With Canon Scanner

Hi all, firstly though Merry Christmas to you all.
I have a problem with my Canon 8000F Scanner and Vista Ultimate SP1, I have installed all the new Canon drivers for Vista and the Scanner is listed correctly in Device Manager drivers showing correctly and This Device is working properly all there. PhotoShop will start up Canons Scan Gear and start the Scanner warming up lamp about 15% then I get the message "Can not communicate with Scanner" cable may be disconnected.
I have tried all of the USB ports but all are the same working with any thing else but. The Scanner works correctly when plugged into a XP machine.
The Vista machine has only 1.5 Gig of ram at the moment, but so has the XP machine CPU is AMD Athlon 64 3500+
Any ideas ??

Hi Hawk,

If the Scan Gear software was made for Win XP, have you checked for any updates for it for Vista. You might need to run it in Compatibility mode or right-click on the .exe and select Run as administrator.

I might uninstall and reinstall the Scan Gear considering the drivers were updated.

Merry Xmas to you too.

Hi Matt, Pete, yes Pete that is the one that I am trying to use.
I also have installed the Vista Tool Box that seems to work ok.

 

Does that mean the problem is solved?

 

No, no change Matt, I had to install the Vista Tool Box as Vista does not recognize the original that is on the Installation CD and there is no problem with that, pressing any of the Buttons on the Scanner front to Copy, Scan, or email will bring up the corresponding function, and that is the point when the problem starts press Scan and the Scanner will start up start warming the lamp then "Can not communicate with Scanner, driver will be shut down" Check Cable it might be unplugged is the message that comes up.
And this is the stupid thing about it if the cable was unplugged it would never be able to get to this point in the first place. 1.5 Gig of ram should be enough to get the scanner crawling along I thought.

 

Hawk, RAM (memory) should not play any part in running your scanner...unless maybe, you have a gross deficiency in memory. I run 1GB of RAM on my Vista machine, my scanner runs fine. A Win 98 computer with minimal RAM might be able to run the scanner. You can look up the System Requirements for your scanner, but I don't think you will find it needs 1.5GB of RAM (that's more than very large programs need to run). It should only utilise minimal memory.

Your problem is probably in the scanner software or drivers. If you have "upgraded" to Vista, it may not be able to run the old drivers/software, even though you have found updates.

Try booting into Safe Mode, uninstall all the scanner-related drivers and software, then boot back into normal mode and install the Vista compatible drivers/software again.

Hi Matt, yes I have done that, I also have downloaded the Canon removal tool and cleaned up the old drivers and installed fresh. No change still the same.
And no I did not think that 1.5 GIG would not be enough Ram even in hungry Vista.

Hi Guys,To make this more confusing (me) or maybe ring a bell for someone, I have been trying with different Photo Editing programs using Twain import. Vue Scan is actually working the scanner it will go past the 15% in the Lamp warm up and preview and scan except I can not get a acceptable color in the scanned image.
This makes me ask the question (I don't know much about it) could this be a IRQ conflict.

I haven't dealt with many scanner problems.

I would make certain that the drivers and Canoscan software were installed correctly. Drivers, you could try booting into Safe Mode, going to Device Manager and in the View menu select Show Hidden Devices, it may be listed there (or check in Control Panel -> Programs and Features). I might try uninstalling the Canoscan software before uninstalling the drivers. I might also uninstall the USB Controller drivers, just in case, and then try to reinstall everything fresh after rebooting (have the scanner disconnected and follow the installation instructions). Do you install the drivers first, the Canoscan or connect the scanner and direct the Add Hardware wizard to the drivers?

It talks about the cable, so I would try another one if one was available.

IRQs? If you can see what IRQs it might share with other hardware by going to Start and typing in System Information -> Hardware Rescources -> IRQs.

Thanks Matt and Pete,
I had a look in Hardware Resources > IRQ , and Conflicts/Sharing, and to me it looks ok nothing indicating problems and in problem devices there is nothing listed either.
Now I don't know if this is good or bad but in IRQs under IRQ 21 there are 5 items the 4 VIA Rev5 or later USB Universal Host Controller and the VIA USB Enhanced Host Controller but they all have a OK. So I think this puts payed to that idea.
Matt the Scanner is properly listed in Device Manager recognized as Canon 8000F and working properly same goes for the scanning software which ever I use Acquiring Twain brings up Canon 8000F select acquire Image and the scanner starts up Scan Gear comes up the light beam moves up and down warming up lamp and it proceeds to 15% and then it cuts out "can not communicate lead may be disconnected" Up to that point it works exactly as it does in XP works perfect in XP. Thing is if the lead was disconnected it would never be able to get to warming up the lamp or bring up Scan Gear.
I have uninstalled driver and scan gear in safe mode, used canons uninstall utility re-installed following the instructions from canon a dozen times with the result exactly the same every time no variation except when I use VueScan it will scan but the scanned image is wrong in color and I can not manipulate it to get it right.
I downloaded a trail version of Silver Light and this won't work either.
Something is missing somewhere but where.

I have made some progress not fixed, but progress.
In my search for a solution I was reading through a German Forum in digital photography and scanning and a gentleman there had exactly to the letter the same problem with a Mustec scanner, he was advised that the scanner was to old and to turf it, which he did and bought a brand new Canon 8800F Scanner but his problem remained exactly the same.
"Cannot communicate with scanner.
Cable may be disconnected.
Check status.
Scanner driver will be closed.
Code: 2.155.0
Same message that I get. Lucky for him his scanner was brand new and he could get canons support and it is a USB problem, unstable.
He managed to fix this with new Motherboard drivers and a BIOS update not knowing which did the trick, but it did the trick.
This brings me back to my IRQ where I have 5 USB items sharing 1 IRQ could this be the weak link.
I checked on my XP machine where the scanner works great and there are only 2 USB Host Controllers on one IRQ and the Enhanced Host Controller is on its own ,on the Vista machine they are all together.
Can anyone explain to me how, if at all possible to change the IRQs, I think this would be worth a try.
What would happen if I Disabled USB 1.1 Controller in the CMOS Setup Utility, it is enabled at present. I only use USB 2.

I cannot easily see how to change IRQ settings in my Vista system. The manual settings are greyed out.

If you have any PCI cards, you can try changing it/them to different slots. That can rearrange the allocation of resources. Doing some websearching, someone mentioned that USB resources can be shared with one of the PCI slots, but the resources may not be reallocated unless the PCI card/s are changed in the slots.

Have you installed Vista drivers for your hardware from the drivers CD supplied with the motherboard/computer? Have you looked for updated drivers at the manufacturer's website?

If you disable USB 1.1, the USB may not work at all, because I think you will find both controllers are needed to run them. You can try disabling hardware items in the BIOS, but change them back if the problem is not solved (don't change any graphics settings or you might reboot to a blank screen, if you disable drive controllers, the drives won't work). Like Pete though, I don't think IRQ sharing is the cause of your problems. Why don't you concentrate on drivers like the information you mention. Investigate a BIOS upgrade, but leave it as a last resort.

Hi Matt, well joy at last, my Canon Scanner is now working fine in Vista, I have tested the scanner in a number of photo editing programs that I had trail or free full versions downloaded. I went back into the BIOS and changed the
PCI 1 IRQ Assignment from Auto to 7 and this fixed the problem. So far anyway I have tested the scanner for several hours scanning different items in varying programs, turned off the PC and restarted turned the scanner off and on and it has not failed yet. My No. 2 Christmas present.
Well Matt I thank you for your continuous support and hope you have a wonderful Christmas.
