 Hey, guys, it's Kevin. You might get this error that you have original document jammed in the scanner. But when you open it up and nothing there, or even worse, you get this 61 error with a whole bunch of zero and the 4A. Most likely your scanner cable are loose. Open the scanner and use a screwdriver to pre-back the hinge. Remove total of 10 screws from the top. There are two tabs on the LED panel. Just push them in and now you can remove the LED panel and then the top cover. Here are the cables that you have problem with. Probably it's because every time you open up the scanner, it pull off the cable a little bit. So make sure they tuck in and secured. Hey, if you need a longer video, just check out my YouTube channel.
