Question about Brother MFC-7820N Printer
When I copy a document using the automatic document feeder, I get couple parallel black lines down, close to each others on the printed page. When I copy a page from the scanner glass, or print an MS Word document, the printed pages are normal. I received a fax recently and the prints were OK, without black lines. It seems that the trouble caused by the automatic document feeder when I use it.
This is caused by dirt/debrise on the ADF (automatic document feeder) scanner glass. You need to open up the feeder where your originals are fed in and look for a strip of glass that runs from front to back. It is about an inch or so wide. You need to clean this glass to get rid of the lines. Some models have this glass just to the left of the large main glass, but in your case I beleive it is in the feeder itself.

THANK YOU SO MUCH! We almost bought a new drum but didn't have to because this fixed it. It's amazing that it's the simple things. The manual for this machine said NOTHING about cleaning that glass strip.
