If using page size = scanner's maximum we get either a solid black page or the document is offset to the left. This problem only started after we updated the scanner driver.

Solid black in a copy typically means that the scanner is partially blocked. Open the top, where you'd place a sheet to be copied, and examine the small strip that runs down the side (left, most likely). See if it's clear, or if something is covering part of it.
Most copiers don't use the full size scanning plate for copies, but use a strip that scans the paper as it moves across it. If something blocks part of it, you get the black area.

Two step process, scan and save the image, then print and select landscape

Try scanning a few documents in full size mode (scannerrs maximum), If you observe a line in the same location in all images, you can conclude that there is either a scratch in the glass (due to stapler pins) or dirt stuck firmly. Try cleaning with Isopropyl alcohol. For absolute emergency, you can wet a cotton bud in after shave and clean the right spot, take care not to touch any other part other than the glass. If glass is scratched, you need to replace it.

It could be 2 things...

1. Your scanner glass is dirty...open the doc feeder and clean the glass. probably Wite-Out.

2. A segment of your scanner assembly lamp is burned out. Not good, uneconomical to repair.

The scanner lamp is not working. When making a copy, the lamp lights the source document, so if there is no light, the source document 'looks' black. Your machine will need to be serviced.

In Captureperfect, select page size as 'Scanners Maximum'. Select automatic paper size, check the output now. If you select bigger paper size and smaller paper, you will see lack output, outside the paper area.

U should select 'Scanners maximum'  and try this. I have found this does not work midway, after some scans. So close and exit out of captureperfect, re-enter and try. This should work.

I have a Brother MFC-8840Dn (full legal-size flatbed as well as document feeder). I use Windows XP Pro and a USB connection. I'm not sure my fix works with other Brother models or different Windows operating systems, but it's a way to start troubleshooting at least.

I've always been able to print legal-sized pages from word processing or spreadsheet programs and receive legal-sized faxes. But I never could make legal-sized photocopies or PDF scans. The image was always cut off at Letter size. The fix is a Brother Utility set-up setting:

*** Go to Start / All Programs / Brother / MFL-Pro Suite MFC 8840Dn / Scanner Utility. (This link may also be called something like Scanner Settings.)
*** At the "Maximum Scanning Size", select "Legal" instead of "Letter/A4".
*** Click OK and restart your PC for the new setting to take effect.

It's like magic -- I can now scan a full legal-sized PDF, whether on the flatbed or through the ADF. I also tried a compressed TIFF scan and it came out fine.

**** Make sure your software and/or Brother Control Center scanning configurations are set to Legal if that's what you want for the particular image scan. The Brother Utility setting simply enables the option of choosing the larger legal-sized paper, which then allows the full legal-sized image scan, You always have to set your software to make that choice, just as you would to make and print smaller images on Letter, A4, envelopes, etc. (NOTE: I always start scans through software on my PC, like Adobe Acrobat or PaperPort, and the Utility Setting fix is working fine. However, I just tried pressing the SCAN button on the front panel of the MFC itself with a legal-sized document on the flatbed and through the document feeder. I still got Letter-sized image scans. So, there must be another setting somewhere for starting scans directly from the MFC that I'll locate later.)

I was about to buy a different brand of scanner because of the frustration with legal-sized images. It's like having a new scanner now :) I hope this Utility Setting info helps you troubleshoot your legal-sized image problem.

Loading originals to scan
Use these instructions to load originals into your device for scanning. For the best quality
scans, use the flatbed scanner. See Selecting media for the automatic document feeder
(ADF) for guidelines on choosing original documents for scanning.
Loading originals onto the flatbed scanner
1. Make sure that the automatic document feeder (ADF) input tray is free of media.
2. Lift the flatbed scanner lid.
3. Place the original document face-down on the flatbed scanner with the top, left corner of
the document at the lower-right corner of the glass.
4. Gently close the lid.
5. The document is ready to be scanned.
CAUTION To prevent damaging the device, do not allow the scanner lid to fall onto the flatbed scanner
surface. Always close the scanner lid when the device is not in use.
Loading originals into the automatic document feeder (ADF)
input tray
Note The ADF capacity is up to 50 sheets of 75 g/m2 (20 lb) media (depending on the thickness of
the media), or fewer sheets if the stack fills the ADF.
The minimum size for media in the ADF is 127 by 127 mm (5 by 5 inches). For smaller sizes
use the flatbed scanner. The maximum size for media in the ADF is 215.9 by 381 mm (8.5 by
15 inches).
1. Make sure that the flatbed scanner contains no media.
2. Close the flatbed scanner cover and put the top end of the stack of originals into the ADF
input tray, with the media stack face-up and the first page to be scanned on top of the
stack.
3. Slide the stack into the ADF input tray until it does not move any farther.
