SOURCE: Error: "Back cover is open. Close back cover."

We had this problem. It turned out there was actually a piece of paper stuck in the printer! It wasn't so easy to see it from the rear.

We removed the paper from the front by taking out the ink cartridge first. Turned the printer back on and everything was fine.

SOURCE: 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!

SOURCE: Brother DCP 7020 error 'back cover open close

Thank you Daniel - it worked for me!
I just spoke with a Brother Customer Service Rep. and he did not mention this potential fix. He ended up recommending a local service center, but suggested that it might be less expensive to purchase a new pinter instead.

Note to others: the tiny perpendicular appendage is on the (this thin black plastic)flap that you pull down to expose the orange roller. There was a separate black piece on the flap that was slightly bent & "jossled out of the slot" as Daniel mentions.

I hope this works for you as Daniel's advice above just saved me about $170 on a new printer - Thank you!

1Open the upper-front cover and remove the toner cartridge.2
Look into the printer. Remove any jammed sheets of paper that you find there.

  • If the print job only consisted of this one page, reinstall the toner cartridge and close the front cover. Press the pattlnk_10162008_2247-select_button.jpg button to clear the error, and then try printing again.

  • If the print job consisted of more than one page, confirm the entire paper path is clear before printing again. Do the following:


    1. Remove the top paper tray ('Tray 1').
    2. Remove any jammed or partially-fed sheets of paper you find here, then reinstall the tray.
    3. Go around to the back of the machine and open the upper-rear cover. Remove any jammed sheets of paper you find, then close the cover.
    4. Once you have confirmed that the entire paper path is clear, reinstall the toner cartridge and close the front cover.
    5. Press the pattlnk_10162008_2247-select_button.jpg button to clear the error, and then try printing again.


  • If you cannot locate any jammed paper under the toner cartridge, then check the rest of the printer for any jammed paper. Do the following:

    • Remove the top paper tray ('Tray 1') and look for any jammed or partially-fed sheets of paper.
    • If you do not find any jammed pages there, reinstall the tray and go around to the back of the machine. Open the upper-rear cover and look there.
    • If the entire paper path appears to be clear, close the rear cover and power off the printer. Reinstall the toner cartridge and close the front cover. Power the printer back on. If a 200 error continues on power up, a sensor in the printer may be malfunctioning. This will require a service call to correct the issue. Please contact Lexmark Technical Support for additional information (see Contacting Lexmark Technical Supportbelow for details).

My Dell MFP 1815dn has a paper Jam 2. I removed the toner cartridge and pulled the paper out, before I realized that I needed to open the back. I believe I thought I got the paper out, but the printer is...


After a paper jam occurs in the rear cover of a Dell Laser Multi-Function Printer 1815N, the printer will not resume when the jammed paper is removed. This is the normal behavior of the printer as there is no sensor on the rear cover of this printer.

To open the back cover and remove any stuck paper, perform the following steps:
  1. Open and close the front cover.
    The jammed paper may automatically exit the printer. If the paper does not exit, go to the next step.
  2. Gently pull the paper out of the output tray.
  3. If you cannot see the paper in the output tray or the paper does not move when pulled, open the rear cover.
  4. Skip to step 9. If you do not see the paper, go to the next step.If you see the jammed paper, push the two blue pressure levers up and remove the paper.
  5. Release the blue strap, the rear cover stopper, and fully open the rear cover.
  6. Unfold the duplex guide fully.
  7. While pushing the fuser lever to the right, open the fuser door. NOTICE: Make sure to unfold the duplex guide before opening the fuser door, or the fuser door may be damaged.
  8. Pull the jammed paper out.
  9. Return the levers, fuser door, rear cover stopper, and duplex guide to their original position.
  10. Close the rear cover.
  11. Open and close the front cover.
    Printing automatically resumes.

Lcd shows "Front or Rear" (Cover Open). What is


There is probably a broken sensor on your printer. Try to open and close the cover some times it works.

2. Remove the jammed paper by gently pulling it straight out.

4. Insert the toner cartridge and close the front cover.

If the paper is jammed in exit are follow these steps:
1. Open and close the front cover. The jammed paper is automatically ejected from the machine.
2. Gently pull the paper out of the output tray.
- If you do not see the jammed paper or if there is any resistance when you pull, stop and go to the next step.
3. Open the rear cover.
4. Carefully remove the paper by pulling in the direction.
- If the paper tears, make sure that all of the paper fragments are removed from the printer.
5. Close the rear cover. Printing automatically resumes.
