    I have the same problem and it won't even let me turn it off. Where is the sensor discussed located?



    Thank you, Anita

    "Cover open" is showing even when the cover is closed. The copier will not turn off when you attempt to turn it off. Tried unplugging it to reset it to no avail. Still shows "Cover open" when the cover is closed.

    cover open has frozen printer with cover closed

  • Anonymous May 12, 2008

    I GET THE "COVER OPEN" WHEN IT IS CLOSED. I L MOVED THE PRINTER AROUND AND FOUND A LITTLE WHITE "PEG" LOOSE INSIDE. I SUPPOSE THIS THE "SENSOR HAND" THAT TELLS THE PRINTER WHEN THE LID IS CLOSED. IT LOOKS LIKE IT NEEDS TO BE SNAPPED BACK BUT CAN YOU PLEASE TELL ME IT ACTUALLY GOES?

Hello Sande.
Try cancelling the printer job via the control panel in Windows.
Also open covers, including the top flatbed half, to view the paper path.
There may still be a stray piece stuck in there somewhere.
Does this help?

Hi, my printer keeps saying cover open even though it is not have opened printer up but do not know which way back to put the white piece thanks


Remove the sheets of paper. Open the printer cover and remove the cartridges as well. Close the cover. Then unplug and replug the printer into the power outlet to reset itself. When the printer turns on, reinsert the cartridges when prompted. Load some paper. Check for any error. Try to print.

The printer displays a 'Cover open, please close cover' error message, even though the cover is closed.

This can happen if the lever on the cover open sensor is knocked off the switch assembly.

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.

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.

Cover open error


There is a latch that preses a small switch when you close the cover (look for this) to indicate that it it close if it is broken you can tweek it using a toothpick or anything that may press the switch temporarily this may alow it to work as long as the switch stays down.

Printer cover open error message


I had that problem too.

Unplug the printer.
Hold the printer cover open while you plug in the printer.
Then wait for the printer to power on while still holding the cover open.
Then close the cover.
The buttons should work and th error message should be gone.

It worked for me.

Printer Error Message after changing the cartridges


I'm not even pulling up any info on that error msg.

Where are you reading the error msg from, within Windows? Or from the printer itself?
