Canon Scanner Problem

Thought I had this solved before, but was wrong.  Running Win98 and have downloaded the most current drivers from Canon, for my FB630P scanner.  About every 4 or 5 days or so over the last month I've had to reload the drivers or none of my PSP5-type programs would acknowledge I even had a scanner connected.  Now, as of the first of the year (Y2K?), when I do a Calibration or Preview the background is always pink.  Saw this over a year ago and solve it with new drivers.  Now.........it's back..............
Any ideas?

Don, how is this scanner connected to the PC?

Dennis,
Parallel, the way it has been connected all along.  Connection is made, of course, from the computer, to the scanner, and then to the HP870 printer.
Removed the printer from the loop, uninstalled and then reinstalled software; same thing.  Software is the latest from Canon, for Win98, and has worked fine until the other day.  I've wondered all along if it is in any way tied into the lost of the scanner drivers after a few days?

I've never been a proponent of multiple devices on the same channel unless it's scsi, but too each there own. I suspect that Windows is having problems identifying the device and thereby unloading drivers for a device it cannot see, but its difficult to determine that without allot of checking. Boot into safemode and go into device manager and review each area and search for duplicate devices of any kind and let me know if you find anything.

Dennis, Everything checked out correctly.  Figures. Each and every device was shown to be working properly with no conflicts.  Think what I'm going to do is sell this scanner, take your advice, and get a scsi or usb.

Don, rarely do I recommend specific manufacturers, however HP has always been good to us and all those that we have sent to them. Their computers aren't worth too much in my estimation, but they have always stood behind their printers, scanners etc. I personally use a 6200 series via USB and my other half uses the 5P. I had aproblem briefly with mine about 6 months along with a faint yellow line during the scan. I called them on a Thurs, FedEx arrived for a pickup on Monday and I had it back in hand by Friday.

Actually the 6200 was one of two I was looking at.  Before I award points please take a moment and take a shot at explaining to me why drivers can just pack their bags and take a hike?  Additionally, I must admit, that I do get a lot of weekly complaints from customers to complain about parallel connected scanners.

Some of your questions are easier than others.

<why drivers can't just pack their bags and take a hike?>

Much of this depends on how the drivers were written. The better companies take greater care in writing their drivers by using the MS software development kits, therefore the drivers are, in most cases, windows friendly and easier to get rid of. On the other hand, depending on complexity of the device features, many driver installs modify existing windows files, such as DLL's, and INF files. If they are removed, the system crashes or comes close to it. Its a dependency issue and whether the device requires kernel access, DMA etc.

There are ways to get around this, but doing so is not for the faint of heart. A little trick we use to get rid of devices is to open regedit and search for all keys that end in ENUM and delete everything beneath it. This will cause your system to rebuild the device list. But like I said, it isn't for the faint of heart.

A good little investment is Drive Image from Powerquest. This will allow you to play and always get back to where you were before you started playing.

<<I do get a lot of weekly complaints from customers to complain about parallel connected scanners>>

We all do. As an OEM, we do not support any form of parallel or COM port connected scanner attached to one of our systems. We won't even support them if we are offered a separately paid contract.

<<Lastly, don't you ever sleep>>

Sure I do, but most of my work is done from my desktop, and since our mail servers are always up and since I am my own boss, I can monitor activity here while doing what I have to do. It's also nice being your own boss.

Will leave regedit alone for now.  Thanks for making things clearer.  I also am my own boss, and it is nice, but lonely at times.
