Moveable Blackline Sensor Option

980611-001 Rev. C GX420d™ / GX430d™ User Guide 8/4/10

Adjusting the Moveable Sensor for Black Marks or Notches

The blackline sensor looks for non-reflective surfaces such as black marks, black lines,

notches or holes in the media which do not reflect the sensor’s beam back to the sensor’s

detector. The sensor and it’s black mark detector are next to each other under the sensor cover

(dark plastic cover translucent to the sensor’s non-visible light).

The sensor can be adjusted by two methods:

1) Preferred - Aligning the movable sensor’s alignment arrow to the right side of a black mark

or notch located in the center or left side of the printer, or

2) Align the center of the sensor cover under the oval notch or a right hand black mark (or

notch).

The sensor should be set as far as possible from the edge of media. The media can move from

side to side and notches cut into the side of the media can become damaged.

Load the media. Before closing the printer, adjust the moveable blackline sensor as follows:

Flip the media back over the roll to expose the black marks or notches on the backside

(non printing side) of the media.
