The head gap sensor is an important sensor that detects the height of the object. Improper setup of the object to be printed or problems with the way the object is secured may result in damage to the head gap sensor.
Object Height Detection Method
The flat table (A) moves from the back to the front and the head gap sensor (B) comes into contact with the object (C) to detect the height of the object.
Risk of Head Gap Sensor Damage
After detecting the height of the object, the clearance between the object (A) and the head gap sensor (B) is set to 0.5 mm (0.02 in.).
However, note that the following operations or situations may cause the object to come in contact with the head gap sensor and damage it.
The top point of the object is higher than the head gap sensor.
The flat table is moved from front to back in an attempt to set the printing zone before setting the height of the object.
Media with a lower height than the installed object is selected, and the printing area is set and printing begins without the user noticing the selection error.
The flat table is moved from the front to the back while the object is not firmly secured to the flat table (i.e., the height of the object may change).
After fixing a warped object with tape and setting the height, the tape partially peels off due to the warping, and the object strikes the head gap sensor when the flat table moves.
The rotary axis unit is not recognized.
The rotary axis unit is installed on the flat table, but the connector of the rotary axis unit is not connected to the main unit or is not connected correctly.
