Have HP P3005 getting message "Close Top Cover", I have switched out sw 501 that detects the door being closed or open, switched out Engine controller unit, and the formatter for laughs. still get the same message. Are those the only parts that detect if top cover is open or closed? Thanks for your help!

There is a Daughter board is what I call it that runs the sensors in this unit that is not responding to the door at all and the switch is open.. There are sensors not the switch itself that is not the sensor on this unit. This is one of those parts that would need to be ordered from HP but you need to be a company that repairs them before they would send you out the replacments so you may have to do third part aftermarket OEM on this, Good luck with your printer it is a good one and worth the salvage!!

Keeps saying cover is open/ please close the ADF cover

The message indicates that the printer door or the cover located on the top is not closed properly, so you need to re-open the door or the printer cover and close it accurately.

Close door message

The unit should run when out of the cabinet on its track glides. However the small cover lid (door) on top of the machine where you would put Ground Coffee in has a switch sensor on it. The cover acts as a magnetic switch and it must be in the closed position. My display says "close the lid" if left open. Since Thermador tells you to call a repairman for everything (which is hard to find one that can work on it) I've had to take every cover off for dis-assembly and repair. With all covers off the machine the only thing I had to do was to "Jump" the ground coffee wire connecter to make it run with no covers on. It makes great coffee but tough to get repaired. Let me know if that was it.

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.

Keep geting the door open error message for HP Deskjet 3920/3940. What door and how do I close it?

The front cover is the door. Make sure no obstacle resides between cover and chasis.

There is a small switch (under cover) on the left side of the printer.

If for any reason you get same error then insert a small paper between the switch and chasis.

good luck

pls. vote for better service

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.

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.

Door open , close print cartridge access door

I have an HP Officejet 6210 All-in-One. When you open the print cartridge access door there is a black toggle switch that needs to be in the depressed position to let the unit know the door is closed. Something was missing from the topside of the "door" so the switch didn't close. I simply stuffed in some foam material to close this, and the unit operates normally. You will need to remove this when changing cartridges, then replace it again.0a64d2c.jpg
