A Solid black line down the left side of the page


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.

Brother DCP8020D Document Feeder


Clean rubber rollers with metho, run a page by hand of laminate or stiff card threw the doc feeder. Stick it where the paper comes out of DF and ensure path is clear.

Push down on left side or tape down little black switch (rear left corner near glass)while trying to use df to confirm hinge aint the issue

If it is the rollers it should feed when paper is "helped a little" with hand at feed time

Ensure prints ok when using glass instead of df to know it is df problem

doc cover open


Yes there is and I know your problem have a look at the left hinge on lid that you lift to put down an original for copying, it will be breaking apart, the switch is black in that same corner on doc feeder base, as the hinge breaks apart the doc feed lifts in that corner causing "doc cover open" cause that switch no longer gets pushed in when lid is shut

Dodgy repair - tape switch closed, but doc feeder will not work properly/can use glass.

Repair - Easy removal of three screws and replacing 20buck hinge bought from brother dealer...part no.LE8731001 Hinge assy left.

Now that's FIXYA!
