2.2.07 Support Protector Mechanism
During printer initialization, the support protector is latched in the stored position (approximately 5
mm from the left bracket of the main frame).
Just before paper is loaded, the printhead moves towards the left bracket and unlatches the
support protector.
As the printhead moves to the right, the support protector reset spring pushes the support
protector toward the center of the platen. With the support protector in this position, the ribbon
protector and the support protector prevent the leading edge of the paper from curling or folding.
Once the paper is ejected, the printhead slowly moves towards the left bracket. The support
protector is latched in the stored position when it is pushed to approximately 5 mm from the left
bracket.
