How do I perform a semi full reset on my Envy 7640 printer

[SBRose]

My HP 7640 will not copy from glass and the feeder keeps running after the copy is finished and then gives an error message that it didn't detect or couldn't pick up paper...but the COPY was finished.

@SBRose,

Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I understand you need help in performing a reset on your HP Envy printer. Don't worry I'll be glad to help you with this.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the printer before the issue started?

Does that Scanner bulb light up?

Does the scanner bar move when you open the lid & press the copy button?

Have you checked if the unit can make a standalone copy? If ‘YES’ then it means the scan hardware of the All-in-One works fine.

In the meantime, let's try these steps here: 

Please make sure that the printer is connected directly to the wall outlet and not to the surge protector.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Let’s first try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose “Copy” option. If the printer is making a good copy, then the printer hardware is fine.

If the copy comes out fine, then I would suggest you could try to update the printer firmware. 

If your printer connected wireless, make sure to temporary connect the device with USB and then follow the link to check for the latest firmware update if available for your printer, for more details, please go through this link:

HP Printers - Updating or Upgrading Printer Firmware

Option 1: Update directly from the printer

Option 2: Download the printer firmware update from HP Support Website.

If the copy comes out bad, then this could be a possible hardware failure. Before you could contact our HP phone support for further assistance, I would suggest you try to perform an advanced reset on the printer.
