Images coming out crooked when in copy mode. A hardware problem?
The MFC-640CW I use is suddenly making copies that appear crooked, despite the fact that the original (either on the glass or through the feed) is not crooked.

Ensure the guide for the plain paper onto which the image is printed, are pushed up fully. It is possible that the paper is being fed into the paper feed path at an angle if the guides are nut pushed up.

1. To test, print the Help List:a. Press the REPORTS key located on the control panel.b. Press the up or down arrow key until Help list appears on the
display(#2).c. Press Ok. The report should begin printing.Black lines that appear on faxes you send, images
you scan into the computer and copies you make are typically caused by dirt or
white out on the scanner unit. The scanner unit is the mechanism that reads in
the documents that are being copied or transmitted.
I have the exact same problem. It was there since I first bought the MFC-7840W.
Vertical line appears in scans using the automatic document feeder (ADF). Vertical line does not appear when scanning single page (placing it directly on the glass -- i.e. not using the ADF). Cleaning the glass strip for the ADF (or the white pressure bar overhead) does not solve the problem. The problem does not occur with copies using the ADF (using the COPY button which is basically a scan and print). This would suggest that dust and dirt is not to blame because that would also appear on the copies. But since I believe a copy is basically a scan plus print, they should be using the same electronics -- a hardware problem on the scan would likely appear on a copy also -- there is some difference between how they accomplish this.
It's definitely not a software issue since it occurs on all versions of Windows and Mac OS X (and multiple computers). It also does not matter whether I "push" the scan to the computer by using the scan button on the MFC... or "pull" the scan from the MFC using the Brother Control Center software.
