What the error means

Printhead Error message indicates that the printhead (laser scanner) unit inside the printer is not working correctly.
NOTE: On the E250d(n) models, all service errors are signified by the flashing of all of the lights. To determine if this is a printhead error, quickly double-press the  button to see the secondary code. If the !, , and  lights are the only ones blinking, a printhead or a motor failure is indicated.

Step Action


If this is the first time you have seen the error, power off the printer. Wait for ten seconds or more before turning it back on. This gives the printer a chance to reset.




Power the printer back on. If it goes to the Ready state, try printing again. Should the error not return, continue using the printer. Otherwise, proceed with the next step.




If this is an intermittent error, you may want to check the printer's power cable and how it is plugged into the wall.

Make sure the printer is plugged straight into the wall and not through a surge device or power strip. Please try this even if the printer previously worked correctly with this surge device. Power strips and uninterruptible power supplies can cause a low amperage problem, which can trigger a false printhead error.

You may also want to try plugging the printer into a different wall outlet to see whether the printhead error continues. This will eliminate the power source as a possible cause of the issue.
