Epson WorkForce 840 All-in-One Printer

Selected FAQ

What should I do if my printout has lines running through it?
See the solutions below:

  • Print head nozzles may need cleaning.

  • Select a higher Quality Option or Print Quality, and turn off High Speed mode (Windows only) in the printer software.

  • Make sure the paper Type or Media Type setting matches the paper you loaded.

  • Make sure the printable side of the paper is face down. It's usually brighter or whiter.

  • The ink cartridges may need replacing.

  • Align the print head.

  • The printer won't operate properly if it's tilted or at an angle. Place it on a flat, stable surface that extends beyond the base in all directions.
