Questions and answers
How do I print photos and screen shots from my phone onto regular 8.5x11 paper in tray 1 or 2, (not the photo tray)?
Mismatching trays and paper size
To resolve mismatching trays and paper size issues with the Epson WF-7840 Series, follow these steps:
1. Check Paper Size Settings – Ensure the selected paper size in the printer settings matches the actual paper loaded in the tray.
2. Verify Paper Loading – Load the paper correctly in the cassette or rear paper feed slot, making sure it is aligned properly.
3. Select the Correct Paper Source – Adjust the paper source settings in the printer’s control panel to match the tray where the paper is loaded.
4. Use Supported Paper Sizes – Confirm that the paper size is within the supported range (up to 11×17 inches in the cassette and up to A3+ in the rear paper feed slot).
5. Avoid Automatic 2-Sided Printing on Certain Papers – If using loose-leaf or hole-punched paper, disable automatic double-sided printing.
Following these steps should resolve the issue.
