Inside the back door is a black plastic guide, in the center there's a lever that moves when paper goes thru, on the right is a flag that needs to be in between the horseshoe shaped sensor on the right. Make sure the lever moves freely...

    There lever is attached to a skinny black rod, rather fragile. It should move freely. it can get bumped out of place when you remove a paper jam. You can remove the gray plastic guide first, without tools. Be gentle! Then you can remove the black plastic guide and gently jiggle the black rod with lever and flag back into place. Worked for me! Good luck.

Oven light on display says door and now wont heat


The oven will not turn on the heat because it thinks the door is still open. It thinks the door is open because it has a sensor that gets pressed by the door when it closes (look around edges of oven that get covered when door closes) this sensor is wet, dirty or broken so when you close the door the sensor still says its open. Did you clean around the door with a wet cleaning fluid?

Printer quit printing. Screen says fuser cover is open. Where is it located so I can close it?


Your problem: paper is jammed in the back of the printer around/in the fuser.

The Users Manual for your printer is located at:
http://www.brother-usa.com/ModelDocuments/Consumer/Users Manual/UM_DCP_7030_7040_EN_1510.PDF

You'll need Adobe Acrobat Reader (free from www.adobe.com) to view it.
LOCATION:The fuser cover is located in the back - its covered by the panel in the back called
the "back cover" aka "back output tray cover".
2-step fix:
(A) open the back cover - on the back of the printer.
HOW: it flips down
(B) open the fuser cover and remove paper jam
How: Pull the 2 tabs (one left and one right) toward you to open the fuser cover.
(it also flips down to open).
Most of this fix comes from downloading the Users Manual and blowing up page 60 (of 108 pages).

The printer displays the front door needs to be closed, which it is. With this display the printer will not print. What do I do?


Most likely there is a tab that actuates the cover interlock switch that is broken off.
You can look at the area of the machine that the door closes into and look for openings about 1/4 inch wide and a half inch long. There sould be an interlock switch in that opening. Then look back on the door to the corresponding area and see if you find an area the looks to be broken. That is the most likely problem..

Display screen says: door/covers open close covers of relay unit??


I believe the "relay Unit" on that machine is the section that transports copies to either the finisher (if installed) or the exit tray on the LEFT side of that machine. Sometimes neither of these units are present, but the relay unit may still be installed.
There are 2 flip up covers on that section (left and right), and you will probably see that one of them (usually the left one) has come unclipped, or perhaps the plastic clip that holds it closed is broken. If you flip up this unit. You will see a black button at the back end that is engaged when ther unit is closed. If you simply pree this button with your finger, hopefully the message will go away - this may at least help you troubleshoot what is causing the "cover open" message). Even if the clip is broken, it is often just a matter of seating the unit correctly so that the switch is engaged when the unit is closed. There is also the same switch on the right cover that could be causing the problem, but this cover doesn't sem to get damged as often.
I hope this helps. Please let me know.
