This section describes how to adjust and calibrate sensors.
Media and Ribbon Sensor Calibration
Media and ribbon sensor calibration is one of the most common adjustments to the printer settings. This procedure is performed through the front panel.
Indications that the sensitivity may need to be reset are:
•The CHECK RIBBON light is on even though the ribbon is properly installed.
•
Note • Before you begin the calibration procedure, make sure that the maximum length is set to a value 1 in. (25.4 mm) greater than the length of the labels that you are using. If the maximum length is set to a lower value, the calibration process assumes that continuous media is in the printer.
Important • This procedure must be followed exactly as presented. All of the steps must be performed even if only one of the sensors requires adjustment. You may press the left oval at any step in this procedure to cancel the procedure.
To adjust the sensitivity of media and ribbon sensors, complete these steps:
1.From the front panel, press the right oval to start the calibration procedure. The LOAD BACKING prompt displays.
2.Open the printhead.
3.Remove approximately 8 in. (203 mm) of labels from the media backing, and pull the media into the printer so that only the backing is between the media sensors.
4.Leave the printhead open.
5.Press the right oval to continue.
The REMOVE RIBBON prompt displays.
6.Remove the ribbon (if used).
7.Close the printhead.
8.Press the right oval to continue.
The message CALIBRATING PLEASE WAIT displays.
The printer adjusts the scale (gain) of the signals that it receives from the media and ribbon sensors. On the sensor profile, this essentially corresponds to moving the peak of the graph up or down to optimize the readings for your application (for more information, see Sensor Profile on page 49).
When calibration is complete, RELOAD ALL displays.
9.Open the printhead and pull the media forward until a label is positioned under the media sensor.
10.Reload the ribbon (if used) into to its proper position.
