Hello,

This is the manufacter's official manual link:
http://www.brother-usa.com/ModelDocuments/Consumer/Users%20Manual/UM_IntelliFax_750_770_EN_85.PDF

On page 63 it shows you how to open the top cover. You must open the front cover first then open the top cover by pressing the blue levers on both sides of the top cover.

It also has a diagram.

Hope this helps!

Power Folding Top System Components
The power folding top system consists of the following components:
• Folding top control (FTC) module
• Body control module (BCM)
• Folding top control switch
• Serial data communication
• Folding top cover latch actuator
• Folding top cover pull down actuator
• Folding top pump motor with valve manifold
• Position switches and limit switches:
- Pin receiver switch
- Luggage barrier switch
- Folding top cover open switch
- Top open switch
- Top closed switch
- 5 bow raised switch
- 5 bow lowered switch
• Tonneau release relay
• TONNEAU PULL DOWN ACTUATOR Fuse 20 A
• TONNEAU RELEASE Fuse 10 A
• BATT 2 Fuse 40 A
• REAR FOG/ALDL TOP SW Fuse 10 A
• Folding top mechanical components:
- Folding top
- Folding top cover
- Folding top valve 1
- Folding top valve 2
- Folding top valve 3
- Hydraulic lines and cylinders

Folding Top Cover Latch Actuator
The power folding top system includes a folding top cover that is powered open and close by a hydraulic system that is controlled by the FTC module. A power unlatch motor is used to unlatch the folding top cover before the folding top control (FTC) module powers the top cover open. The folding top cover unlatching is requested by the FTC module via class 2 message, but is executed by the body control module (BCM). When requested, the BCM applies battery voltage through the folding top cover release relay control circuit to the tonneau release relay. The relay is energized and battery voltage is applied through the folding top cover release control circuit to the latch actuator. The actuator is energized and the latch releases the folding top cover.

The electronics on this are very complex ,

System Operation
Before any movement of the power folding top is allowed, the folding top control (FTC) module must be aware of the following conditions:
• Unlatch the header. The FTC module reads the pin receiver switch is Inactive.
• The windows must be normalized. Refer to Power Window Reinitialization.
• The ignition must be placed in Accessory or RUN.
• The transmission must be placed in PARK, or with manual transmission, the park brake must be applied.
• Trunk status must not be ajar.
• The luggage barrier must be in place.
• The pump motor temperature must be within the operating range.

After the last cycle of power folding top operation, allow the hydraulic system a minimum of 4 minutes to bleed down before attempting manual operation of the top.
Your best bet take and have it checked for DTC'S - diagnostic trouble codes .

When I try to print, I get the error: Top Cover Open: The printer cannot print because the top cover is open. How do I fix this?


Hi cduckyquack ,

  • All you need to do is close the printer cover if it's open , once it's closed you should be able to print correctly without any warning messages.
  • If the cover is closed and still you are getting the same message , then it might be a problem with the censor switch which indicates to the printer whether or not the cover is open, so if the switch / sense has gone faulty then you need to repair it.
  • Sometimes just because of dust the printer does not sense the cover being closed and it results in the error message that you have described.
  • Hope this helps ...) your feedback would be appreciated.

Error message top cover open


When the printer is used often, and ink and dust accumulate inside, the detector switch will sometimes get stuck and won't be depressed by the cover correctly. Open the cover and look right next to the sticker. There is a small rectangular hole with the switch. Use a very thin tool like a small screwdriver or paperclip bent open to push the switch inside the hole to the back of the printer. Do NOT push it just down! You *must* move the switch away from you. Hold the switch in this position and close the cover. Carefully pull out your tool from the gap.

The "cover open" message displays and it will not go away.


there may be any struck between the cover open switch which is in main board of the printer and the lever in the cover. open the cover and press the lever behind the cover. if the cover open message go away then do the same for 2 - 3 times after close the cover and try. even now he same problem happen make some arrangement or stick a paper bit on the top of the lever so as to enable it to press the sensor properly

HP Deskjet 5150 - top cover open


I had the same problem, and the cause turned out to be the cover switch not being fully pushed in. On the underside right edge of the top cover, there's a little triangular protrusion that pushes down a black rectangular button (the cover switch) when the cover is closed. The problem occurs because the flimsy top cover is made of plastic and flexes slightly when you close it. This means that sometimes, the right edge of the cover won't seat properly even though it appears as if the cover is closed all the way. When this happens, the triangular protrusion isn't fully pressing the switch down.

To test if this is this is happening, send a print job to the printer and wait for the "top cover is open" error message to appear. Next, open the top cover door and locate the cover switch. It's a little black button in a rectangular hole at the right edge of the doorway near the ink cartridges. Take a pen or a car key and use it to push the cover switch down. You can also use your fingertip to do this if it's skinny enough. If you keep the cover switch pressed down, the power button should start blinking to indicate a print job is coming through. If the print job actually starts printing, then you know the problem was the cover switch.

In my case, all I had to do the fix the problem was close the cover and make sure it was fully seated by firmly pressing down the right edge of the cover until I heard a plasticky "click" noise. After that, the problem went away.

Hope this helps.

Brother MFC 7820N error message "back cover open" but cover is closed. machine is now not functional as error message can't be removed


If you open the back cover (depress the release button on the top right) If you lift it up look for two black anchors that grab the base when you close the lid. I have one that has a broken tab on the left side, which happens to be the same side as the cover closed switch. If the top is not closed all the way the rollers do not line up and the cover switch is not depressed to let normal operation. Also, if the switch arm is busted (case colored plastic push pin protruding from the cover) it will not make contact with the switch when closed. Try closing the cover and push down on left side of the fax. Does the error go away? If not, the actuator arm or the switch are bad.

Cover open Error message


I'd say maybe the switchs is broken and your machine reminds me of a lexmark fault. Look for the cover switch, under lid on base, at rear, small hole, find the switch that get's activated when openning and closing the top, maybe it is missing, or broken.

link to lexmark fault, that I think you will find your answer.

B door open


There are two switches, so if you changed the one that was working....

Possible parts affected could be
- cover top
- cover fuser
- cover front assembly
- the switch
1) check the condition of the cover - top, front assembly and cover fuser closed?
2) on the cover top there is an "actuator", a plastic bit, which presses down on the switch assembly top - is that plastic bit broken, bent or deformed?
3) on the cover front assembly there is also an "actuator", check this
4) and of course same for the fuser cover
5) top cover, check the switch, disconnect the switch (P116-1) and press/release it - does that make a difference. If not replace switch
6) same procedure with the switch (P115-1) for front cover.
