Blackline Threshold Calculation Example

Follow the process outlined below for an example to determine the blackline or reflective
sensor threshold calculation. The values reported will vary depending on the different types
of media used.
1. Verify that the sensors are clean and are unobstructed.
2. Load black line media into printer.
3. Establish communication with a terminal emulation program (HyperTerminal, Tera
Term Pro, MCT, etc.).
4. Be sure that the printer is in the reflective detection mode selected is a "1" by issuing
the "^D636)?" command.
5. Enter Tic-Tic mode by issuing the "^D900)f,3" command.
6. The printer will return a numerical value for the sensor output selected by the ^D636
command.
7. A high value should be returned for the area outside of the black line. A low value
should be returned when the black line passes over the black line.
8. Enter a new threshold value (between the high value and the low value) using the
Black Line Sensor Threshold command ^D681)n
