Envy 7640 won’t recognize platen

[DA88]

Since i fed a thin sheet through the feeder, the feeder gives an error message and will not clear the message to refeed. It is also stuck on wanting to use the feed, i cannot get it to recognize the platen for copying and scaning. I’m fine just using the platen.

Hi@DA88,@, Welcome to the HP Support Community!

I do understand that you are having trouble getting the printer connected to the network / PC. To assist you with this issue, I need to know the operating system on your PC. Please reply with the detail

For better clarity and to assist you better I would require more information regarding this:

• Did this happen after a software or Windows update?
• Did you try to uninstall and reinstall the printer drivers?
• Did you try to run HP print and scan doctor on the affected computer?

For a start please try these steps:

Please run the HP print and scan doctor from this link: http://hp.care/2syjvp6;

 and check if the issue gets resolved.

If it does not, then please uninstall the printer drivers by following these steps:

• Uninstall the printer from "programs and features" which can be accessed by doing a right-click on the Windows button (Please have the printer Off and disconnected during uninstallation.)
• Check-in device manager, if the printer is listed there, please delete it. (Right-click on the Windows button to access device manager)
• Go to devices and printers, select any printer listed there and you will get some options on the top.
• Click on print server properties.
• You will get a popup, click on the driver's tab and delete all the HP printer drivers listed there if any.
• Delete all the instances of your printer listed in devices and printers.
• Restart the PC.
• Once the PC is on the desktop, press Win + R, it would bring a Run dialog box,
• Type %temp% in the run box and click Ok or hit the Enter button.
• It would bring up the temporary files folder. Delete the files in the folder (You might not be able to delete all the files).
• If possible, delete the printer from the registries using Regedit or using any other 3rd party application.
• Ignore the Regedit option if it cannot be done.
• Restart the PC again.

Then download the latest full feature driver from http://hp.care/2tt9z1h and install it on the computer after selecting the correct operating system.

Connect the printer to your computer only when the setup prompts for the printer.

This should do the trick for you.

Keep me posted. Happy to help!

Nope. Not a network issue.  
when i put an item to be copied or scanned on the glass, it is not recognized. The machine is only looking for input from the feeder which isn’t working.

Hi @DA88,

Welcome to the HP Support Community.  

As this is a hardware issue, I'd suggest you Contact HP in your region regarding the service options for your computer. 

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile Name, you should see a little blue envelope, please click on it.   

Have a great day!
