meet, the threshold count is calculated as the sum of half of the differential between the Low and Hi AD counts captured plus the Low count. When a valid BOF has been found it is saved and used as the threshold for the TOF.

The next transition edge of importance is the TOF. It is defined as the trailing edge of the feature. Once the BOF has been found the software looks for a TOF. In fact it uses the same AD threshold count calculated for the BOF. The difference is that the TOF point is determined as the AD count passes through the threshold from the feature back to white.

The threshold value used for this first feature is not saved in the averaging array because it only represents the minimum span distance as defined by the algorithm criteria. However, by the time the TOF position is reached a full representation of the signal profile has been captured and this actual profile is what is used for BOF/TOF on the second feature.

When the second feature passes by the sensor the valid BOT and TOF are those points that were calculated from the first feature. The threshold points calculated based on the signal profile captured from this feature are saved as the second entry in the array. For the third feature the threshold points become an average of the first two features. Here after the array is continually updated containing the last two threshold values.

The calibration function is complete when the second valid feature is found and measured. The existing software has processed the physical aspects of the label such as print length, feature length and TOF to TOF distance into the tracking system. The software can now track the label just seen by the sensor so that it will be synchronized in correct position under the printhead. Knowing label length provides the ability to predict when the next feature can be expected. Therefore, the only time the sensor will be enabled is after calibration during the window of time when the feature should pass by the sensor. The reason in using a small window is to minimize detection of extraneous pulses that may adversely affect the accuracy of the algorithm.

∙Ribbon Tension Adjustment

NOTE: Field Service performs no electrical adjustments.

Bi-Cell Sensor Adjustment

1.Turn Printer Off.

2.Load die-cut supply and turn off printer.

3.Connect laptop computer to printer’s serial port (laptop must have SENDFILE V2.07 installed).

4.Set DIP switch 3 (bottom set) to ON (Diagnostics Mode)

5.Set DIP switch 6 (bottom set) to OFF (Die Cut).

6.Turn printer on. Printer will feed two labels and display 000.

7.Start SENDFILE (as follows).

8.Press M for Model number and press Enter.

9.Press Feed and Clear simultaneously on keypad to access Diagnostics. SENDFILE will display

DIAG IDLE.

10.After SENDFILE displays IDLE, press D for Diagnostics.

11.Remove Die Cut labels from the printer.

12.Check the emitter for operation, using an Infrared Detector Probe.

13.Cover the Bi-Cell switch with a piece of black electricians tape. Completely block all light.

DO NOT TOUCH THE SENSOR LENS WITH YOUR FINGERS.

14.With all light blocked from Bi-Cell, note the reading on SENDFILE. This is the reference value for the sensor. Range is 2.35V to 2.55V. If reading is out of range, replace Bi-Cell Sensor.

15.Remove electrical tape.

16.Place gray scale over sensor, glossy side down.

(HANDLE FILTER BY EDGES ONLY. SKIN OILS CAN ALTER THE BI-CELL READING)

17.Close print module and note the Bi-Cell reading in

SENDFILE.

18.From back of Bi-Cell housing, turn adjusting screw to obtain the reference value observed in Step 14.

19.Open and close printhead carriage to verify adjustment.
