Moveable Blackline Sensor Option
6/4/08 GX420d User Guide 980611-001 Rev. B
Moveable Blackline Sensor Option
The factory installed optional moveable blackline sensor allows the printer to use media with
black line(s) or marks or notches (holes) on the back side of the media (or media liner) that are
not located in the center of the media.
The moveable blackline sensor can not properly sense continuous media or labels (for inter-
label gap sensing) if the sensor is not in the default sensing position, see below.
