Media Index Sensor Calibration; Dispenser Sensor Calibration - SATO CX400 Service Manual

MEDIA INDEX SENSOR CALIBRATION

CX-400 Printers can use an eye-mark (black bar) label gap or label notch sensing. The gap and
notch sensor is a transmissive or see-thru type with an infrared light source directed through the
label from above and detected by a separate receiving sensor underneath the label liner tag. A
reflective sensor is used to detect eye-marks printed on the bottom of the label liner or tag. The
eye-mark must not reflect more than 12 % of the light. Since the same receving sensor is used
for all three types of sensing, it must be calibrated with the media that will be used. For thermal
transfer printing, the ribbon must be installed while the calibration is performed.
Media sensor calibration may also be required if the printer frequently fails to print, has excessive
print position variance, or the print image is mis-located. Calibration may be performed by either
clicking on the calibration buttons of the Label Gallery Free software, through the Windows
Printer Driver, or more directly by sending printer commands to the printer. To signify a successful
calibration, the printer will feed 6 linear inches of label upon completion. Perform the applicable
steps below relative to the media type used.
For Eye-Mark Detection
1. Install both printer ribbon and print media while in the prper mode (DT or TT).
2. Send these commands to the printer: <ESC>A <ESC>CI1 <ESC>CA <ESC>Z.
3. Allow the printer to feed 6 linear inches of labels to complete the calibration.
For Label-Gap Detection
1. Install the print media while in the TT mode.
2. Send these commands to the printer: <ESC>A <ESC>CI2 <ESC>CA <ESC>Z.
3. Allow the printer to feed 6 linear inches of labels to complete the calibration

DISPENSER SENSOR CALIBRATION

For Thermal Transfer
1. Place a label in the discharge slot over the sensor.
2. Send the following commands to the printer: <ESC>A <ESC>&P1 <ESC>Z.
3. Allow 5 seconds for the printer to complete the process.
For Direct Thermal
1. Place a label in the discharge slot over the sensor.
2. Send the following commands to the printer: <ESC>A <ESC>&P0 <ESC>Z.
3. Allow 5 seconds for the printer to complete the process.
