Hi@patinge,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing Paper Jam issues with the HP ENVY 7640 E-All-In-One Printer.  

Clear jammed paper from the ink cartridge access area

1. Turn off the printer, and then disconnect the power cord.
2. Open the cartridge access door.
3. Gently remove any paper that is jammed inside the printer.
4. Close the cartridge access door.
5. Reconnect the power cord to the rear of the printer, and then turn on the printer.

I have a few recommendations 

• Paper jams can be real or false. The printer might report a paper jam even when there is no jammed paper. Click on this link for both real and false paper jams. https://support.hp.com/in-en/document/c04367621
• Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again.

Hope this helps! Keep me posted.
