Scanner seems to get stuck at the end of certain scans
I am able to scan fine for ten or eleven times and then for no apparent reason, as the light bit (don't know what its called) is returning to the top of the image, it stops and starts clicking, i can't turn off the power other than to pull out the power supply at the back. When i start up again, it does the same thing! Help!!!

I guess there is a problem with the base station. Let me tell my story:
I got a 4820 scanner with 2020 base. All worked fine till I experimented with scanning images. After a few images (which I cannot retrieve/receive properly due to lack of software) the scanner seems dead. From time to time a short buzz sounds when triggered, but no light or else.
So I bought another 4820, a slightly different model. Seems to work fine but has to be paired with the base to get the data. Now after pairing this scanner shows the same issues as my first and refuses to scan.
I installed QiuckView and HSM-USB-Serial-Driver on a virtual machine at my MAC to flash firmware to base and scanners. But the base device does not show up in the program (althought it is shown in the USB device table). Maybe I can try on a native WindowsPC ...
I had the same problem scanning to PDFs with the CanoScan Toolbox until I went to the File Settings dialog, and unchecked the option "Detect the Orientation of Text Documents and Rotate images". Now it seems to work more predictably (no more scans that have been rotated for no apparent reason).
From what you described it sounds like you need to get the "scanner assembly" replaced. The bulb is probably bad and won't come on to full power. Not knowing what kind of printer you have, probably won't change the fix. If you can look at the event log you may be able to see an error code which could make it a definite scanner assembly replacement. If you want to throw money at this unknown printer, get a tech to look at it and give you an estimate.
Check your scanner software settings. It is probably set at duplex ever time you start to scan. That is why you get two pages for every pass, the front and the back. You must place the document in the feeder in a way that the front side of the document is page 2. You may want to flip it next time you scan. So the main question is why there is black line from top to bottom? That is because there is a piece of dirt stuck on the glass of the scanner. You see, this scanner actually does two scanning when a page runs through it: the front and the back in duplex mode. So there are two scanners in side the box. The front page scanner apparently is dirty and needs to be cleaned with clean cloth and lens cleaner.
There are a couple possibilities that can cause the problem.
1. you need to unlock the scanner. There is a lock at the side of the scanner that could be in the locked position which is preventing the scanner from moving. you can use a nickel or penny or screwdriver to turn it to release it.
2. the tab that is holding the gear is broken 3. the glass is not attached 100% to the upper case and the scanner is hitting it when trying to scan. if its 2 or 3, you might be better off getting a replacement.
I've just got this problem after a powercut, whilst it was not being used but on. If you have only had it a few months send it in warranty. Think I will have to take this apart and see if the scanner cable/ribbon/drive belt is caught on something or been stretched too much and can be replaced at all. Its like at one end its caught and wont move the scanning head being stuck somehow, caught on something (doubtful tho').
I have the same problem. It was working fine, then after not using it for a few weeks, all the sudden I couldn't scan. I'm hooked up wirelessly through my router. I can initiate a scan both from my PC and from the scanner itself, when initated from the scanner my PC responds and shows the progress bar, and the scanner actually scans. However for some reason no data is being sent back to the PC. And after a few minutes I get an error message saying that communication was lost (or something like that) error TW007. Yesterday I called into brother support and was on the phone for an hour and a half. they walked me through verifying connectivity, uninstalling and reinstalling the software and drivers, but to no avail. In the end we made no progress. I can print without a problem, and fax and photocopy. But for some reason it seems that the scanner is not transmitting the information back to the computer, even through the connection was established and the computer is waiting for the data.
All the comments I've seen made regarding similar symptoms to your were
related to the setup of the device. Apparently the device is very finicky and I have heard many people say that the installation process for the scanner has caused a lot of people issues.
Dimage Scan must be executed before turning on the scanner for the first time.
I suspect that the device won't be properly recognised by the system without the software already being installed and configured before the device is attached. I would remove the device, uninstall any trace of it from your system, and try again with a fresh install.
