C. All the three lights are blinking.
Paper is jammed in the printer. To clear the jam, see
below, “When Paper Is Jammed in the Printer.”
If there is no paper jam, turn the printer off and then on
again. If the three lights still blink, call the Customer
Support Center.
When Paper Is Jammed in the Printer
To clear the paper jam, perform the following steps:
1. Turn off the printer.
2. Remove the paper from the paper tray.
3. Open the printer door.
4. Remove the printer door by grasping it by its
sides and then pulling the door up. (Use your
thumbs to hold down the printer while pulling
the door.)
5. Open the paper separator (the flap that
separates the printed pages from the blank
sheets) by pulling it toward you. With the paper
separator out of the way, your fingers will have
a better grip on the jammed paper.
6. Grip the jammed paper firmly by its sides and
pull it out slowly.
7. After clearing the paper jam, close the paper
separator.
8. Re-attach the printer door by first placing the
door flat on the paper tray. Then align the
hinges on the printer door with the pins on the
printer. Press the printer door down until the
printer door clicks into place.
9. Close the printer door.
10. Load paper and try printing again.
