Replacing the Lower Fixed Gap/Blackline Sensor
You must remove the bottom case before performing this procedure.
Removal
The black line (bottom gap) sensor is located at the center of the printer towards the front of
the media compartment.
1. From beneath, open the connector on the Main Logic circuit board and pull out the ribbon
cable from the sensor.
2. Use a #1 Phillips screwdriver to remove the screw that holds the sensor and its bracket to
the bottom, inner frame.
3. Carefully lift the sensor and its ribbon cable away from the printer.
Installation
1. Make sure the sensor is mounted on its bracket.
2. From beneath, align the sensor into place with its ribbon cable to the left and the screw
mounting hole to the rear.
3. Replace the screw that holds the sensor and use a #1 Phillips screwdriver to tighten it.
Replace the bottom case. Reload media. Plug in power, turn on the printer and print a status
report to ensure proper function.
Caution • Prepare your work area by protecting against static discharge. Your work area
must be static-safe and include a properly grounded conductive cushioned mat to hold the
printer and a conductive wrist strap for yourself.
