Cause or Overview

The printhead must be closed and latched to allow the printer to perform any printing functions. A sensor located in the electronics compartment detects the head open and closed positions. When the printhead is opened the printer will be Paused and the LCD Display will display

 ERROR CONDITION
HEAD OPEN


 When the printhead is closed the LCD Display will read

 ERROR CLEARED
HEAD OPEN


Press the Pause Button to clear the HEAD OPEN ERROR.

Solution

If the printer will not unpause when pressing the PAUSE Button and the error persists verify the printhead latch is fully closed. 

If the printhead is obviously closed and the printer still reports a HEAD OPEN error message then the head open sensor needs to be checked.

  • The head open/closed sensor assembly is located in the electronics compartment of the printer. Its components include a rotating plastic flag and a fixed sensor with a slot that the flag moves through. When the print head is closed the flag should be inside the sensor slot. When the print head is opened the flag should rotate out of the sensor slot. If there is a problem with this movement the snap fit button or screw that secures the flag may have come loose causing the flag to be out of position.
