2) Remove the ROM cover located beneath the paper-roll holding area.

•Rotate the main PCB’s sensor adjustment knob (VR4) to the point where the
HEAD UP indicator comes on.
b) Paper-Out Sensor
•Insert a non-black piece of paper into the mechanism’s sensor area.
•Rotate the main PCB’s sensor adjustment knob (VR3) to the point where the
NO PAPER indicator comes on.
c) Transmissive Sensor
•Insert the backing portion of a label sheet into the mechanism’s transmissive
sensor area. (Insert the backing only, not the label itself.)

NOTE: When inserting paper, be sure to lower the head so that it is close to
its normal fixed position.
