Getting a paper tray empty message when there is paper in tray. No matter how many or few sheets are in the tray, I still get the error. Have shut off the printer and re-started, cleared printer cache, no go. By coincicence, this started immediately after I repaced the ink cartridges.
This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂
As I understand the HP Envy 7640 paper tray empty message appears though there's paper present,
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
Did you ensure there's no curled or ripped paper stuck in the rollers?
Have you cleared or cleaned the pickup rollers?
While you respond to that, here's a few things you can do:
Solution one: Check the paper, and then reload it
Follow these steps to check the condition of the paper, and then print a test page.
Paper feed issues might result from using ripped, dusty, curled, wrinkled, or bent paper. The quality of the paper can also make a difference. Follow these guidelines to help avoid the issue.
Solution two: Adjust the paper settings in the print driver
The printer might not pick up paper if the paper size and type in the paper tray do not match the paper size and type settings in the print driver. Select your operating system for steps to change the paper size and type settings in the print driver.
Solution three: Clean the paper feed and pick rollers
Dust, paper fiber, and other debris might accumulate on the paper feed and pick rollers and cause paper jams and paper feed issues. Use the following steps to clean the rollers inside the printer, and then try to print a Printer Status Report.
