Load plain white U.S. letter or A4 size paper in the input tray, if it is not already loaded.
On the printer control panel, touch the Settings icon (looks like a wrench).
Touch Tools, and then touch Clean Cartridges. The printer cleans the printhead and then prints a test page.
Check the test page for defects.
Try printing again and let me know the results.

Try disconnecting the printer from Wi-Fi then add it back to the Wi-Fi
Make sure you are scanning using the new printer that you added and not the old one.
No, I am still here.
I would suggest that you remove the printers from your computer and start from scratch with the software again then go into the scan settings and check the box for Scan to Computer. Disconnect the Wi-Fi on the printer and connect it again then test again.
Interesting that it has reverted back to the blank page printing again. Unfortunately, I am out of ideas on this situation so I will send the question back to the expert pool. You will be notified when another expert responds.
