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: Document Cover Open

I had the same problem with mine. Lift the top scanner, and check the hinges on the left. That error message means that the little black sensor on the left next to the hinges is not meeting flat with the unit when closed. Hold the sensor in for a few seconds, and your printer will start working properly.

SOURCE: Back cover open message

I had the same error message. I also tried every compartment... Here's ultimately what my problem/solution was...

I turned the printer around and fully opened the back cover. I found that one of my kids had somehow fed a small piece of paper/cardboard into the printer. When I opened the back cover all the way I could see that obstruction (which I hadn't seen before). Pulled it out, and the error message went away. Works fine now.

SOURCE: copier will not copy

Look for a switch where the door shuts. Either the tab on the door that hits the switch is broken or the switch is loose or broken.

SOURCE: the error message says Doc. Cover open but the

You will probably have a broken hinge at the back left hand side of the Doc. cover.
This means that the cover won't close properly at the back corner, and the cover sensing switch won't actuate.

"remove original from document processor"


Sensor in feeder is probably broken. To get around this until you can get it fixed power down the unit and unplug it. Unplug the cable that connects the Doc feeder (in the back) to the main unit (two screws hold it on. Then power the unit back up it will work with out the Doc feeder. You will just have to put the copies on the main glass.

HP OfficeJet J5780 Vertical Black Line Prints when copying or scaning only. Cleaned rollers and changed black ink cartrigde. Still problem.


Have you tried cleaning the document feeders Scan Glass? (small glass under doc feeder ~ 1" by 9") Most times there is dirt spot on this glass, causing a shadow on scans and copies.
Try copying from the large glass by lifting doc feeder / platen cover and manually placing original. If no line copying or scanning manually from large glass, then small scan glass is deffenitely the culprit. Hope this helps.

Doc. Cover Open displayed


That usually means some sensor giving you trouble.

This is what brother recomends:

How do I clear the message Cover Open or Please Close Cover from the display?


The message Cover Open or Pls Close Cover may appear if the front cover
for the drum was not closed securely. Verify the cover is closed
securely by pressing the cover release button located in the front of
the unit below the Output Tray Support Flap and open the front cover.
Close the cover until it clicks into place.

If the message continues to appear on the display verify the drum and
toner assembly is installed correctly by following the steps listed
below:

1. Press the cover release button located in the front of the unit and
open the front cover.

2. Remove the drum unit and toner cartridge from the unit by lifting it
up and out. Place it on a drop cloth or disposable paper to avoid
scattering toner.

3. Hold down the blue lock lever located on the right side of the drum
and lift the toner cartridge out of the drum unit.

4. Reinstall the toner cartridge into the drum unit by inserting it in
the drum until it clicks into place

5. Reinstall the drum unit into the unit. Make sure it is securely in
place.

6. Close the cover until it clicks into place


If that doesn't fix it, I guess you will have to talk to their support people.


Good luck!

Canon MF6530 copier


If your copies are clean when you scan them by opening the top and laying the original on the platen, you need to check the scanner for the ADF (automatic document feeder). It's a narrow strip of glass to the left of the scanning platen glass. Clean it with a soft cloth dampened with clear water. (Look for some type of deposit that aligns with where you see the line on the page.)
