Adjust Media Sensors
To adjust the upper media sensor for the outside half of the media:
1. Remove the ribbon (if ribbon is used).
2. Locate the upper media sensor. The upper media sensor eye is directly below the
adjustment screw head.
3. Using a Phillips-head screwdriver, remove the upper media sensor adjustment screw.
4. Lift the upper media sensor assembly from the slot, and move it and the wire cover to the
outside slot. Carefully pull the wires through the cable tie. You may need to set aside the
sensor wire cover if the adjustment is too far to the outside.
5. Replace and slightly tighten the adjustment screw.
6. Slide the upper media sensor along the slot to the desired position (for non-continuous
media with a notch or hole in the media, the sensor must be directly above the notch or
hole).
7. Tighten the adjustment screw.
8. Make sure that the wires are routed back into the groove of the media sensor bracket.
To adjust the lower media sensor, complete these steps:
1. Locate the lower media sensor assembly under the rear roller (Figure 28). The sensor is a
spring clip holding a circuit board.
Figure 28 • Lower Media Sensor Location
2. Slide the lower sensor until it is under the upper media sensor. Gently pull wires out as
needed (wires should have a little slack).
3. If you move the sensor inward and a large loop of wire develops, remove the electronics
cover from the side of the printer, and gently pull the wires through. Clamp the wires so
that they do not touch any drive belts.
