Ribbon Sensor Adjustment Procedure
Use a TOSHIBA TEC-approved ribbon for sensor adjustment.
(1) Set the ribbon so that the ribbon sensor can detect the ribbon. Then, turn the power on.
(2) Turn the VR1 on the I/O PC board so that the voltage between the GND(Frame Plate: Refer to the
figure on the previous page.) and TP1 is 3.0 ±0.2V when measured with an oscilloscope.
(3) Turn the power off and attach the side cover and close the top cover.
