Question about Canon CanoScan 8400F Flatbed Scanner

2 Answers

My CanoScan 8400F stopped working. A local computer shop advised that the power adapter was shot. Rather than spend $60+ with Canon, I bought an after-market through EBAY. When it was delivered I discovered that the plug into the scanner did not match the original although the advertised product specified the adapter was for this model. Can the plug from the dead adapter be spliced into the line from the replacement product?

While you might be able to make this work, the risk of a short circuit and/or electrocution makes this option not very favorable in my opinion. I would suggest returning the non-compatible part to the seller if possible, and you will get most of your money back.
If you decide to go ahead with this in spite of the above warning, I do have a few thoughts:
If you have experience soldering, you might be able to get a professional grade connection by splicing and soldering the correct end onto the part. Be careful of pin polarity (+or- center pin) to make sure you don't zap your scanner. Also make sure that the new part has the same voltage, amperage, etc. as your old one before that. If you decide to go this way you also should be aware that any warranty, either on the scanner or the part you just bought, will likely be voided by altering the device.

I'd try contacting the seller FIRST and letting him know the product does not work for the models he advertised and you'd like to return the item for a refund. If that doesn't work, THEN file a claim with your credit card company or Paypal (credit card is preferable if you paid by that rather than paypal funds) and say the item was misrepresented.
Rather than splicing anything and damaging anything, I'd do that first. Then find a seller with high ratings for the same product. Ebay is the way to go rather than paying ridiculous factory prices.See if you can find the original manufacturer's part # (possibly off your broken power adapter), rather than just the scanner model #, and search Ebay for it, but click the "Search within description" box, as many bay sellers only include the actual part # in the auction description, rather than just the title.

I have a Canon 8400F film printer/scanner

'Tain't necessary. And not getting the part can be an improvement.
I cut out a cardboard template that allows me to scan 10 slides rather than the 4 of Canon's official slide adapter.

All the Canon part does is position them precisely so cropping and rotation are automatic. With Photoshop skills (File ' Automate), you can do the same yourself for whatever size. I ended up doing Brownie, 35, and 126 (gasp!) also.

For extra credit, make your adapter(s) out of genuine plastic rather than whatever cereal box you have lying around.

I have a canonScan 8400F there's a connection with computer however when i open adobe photoshop there's no preview..

I have many years experience repairing Canon scanners so here is my suggestion for you.

I guess I have a couple of questions for you first. Does your computer recognize the scanner is attached to your computer? If so can you scan in any other program like Windows Paint? If you say yes to both of these then the problem is with configuring your adobe software. If you say no then we need to go back to basics. I would google Canon Canoscan 8400F Drivers, it should pull up a page that will take you to Canons official website. Download the latest drivers from Canon's official website,the drivers are dated and the ones towards the top should be the latest drivers. The drivers are free. Also while your there download the newest version of Capture Perfect its a utility program for scanning its free also but download the latest one. Now make sure your scanner is unplugged from your computer, the cable that goes from the scanner to the computer. Install the latest drivers on to your computer. Once they are installed, then with your scanner powered on attach the cable from the scanner to your computer. A window should pop up saying a new device (or drivers) is being installed. Once this completes reboot your scanner and you should be able to scan again.

I use Paint shop and in order for me to scan with my Canon scanner I need to go to aquire and image, from a scanner or camera, and then it controls the scanner and does the scanning for me.

I hope this helps you out.

When set for scanning any color scheme, each page ends up with a large swath of yellow down the right side of the page. Does not happen in b & w. Canoscan 8400f - approx 4 years old.

if this happens even when you turn off all light in the room then your scanner is shot... if not then you have a light source interfering with your scanner
