Install the driver in and connect the printer to another Windows PC or laptop.
- If OK there, it's something in your laptop.
- If not OK there, it's something in the printer.
Then you know what not to change.
I’m running Windows 10 on my laptop. My Epson-3720 just started printing blank pages in Word, and just a solid black line at the top of Outlook messages, that comes out normally on messages, but nothing else is coming out.
The printer prints test pages ok and copies documents ok, so there’s no problem with the printer cartridges. It’s been printing fine for months and I haven’t installed anything new.
I’ve downloaded new drivers and utilities from Epson, but this didn’t help. I’ve run the printer cleaning procedure several times, and the cartridges have plenty of ink in them.
A weird thing – in the Device Manager, my Epson printer comes up as “Unknown Device”, but my HP printer comes up correctly as an “HP” printer.
