6.2.3 CALIBRATING THE ID SENSOR
NOTE: After replacing the ID sensor, calibrate it as described below.
Without calibration, proper color densities may not be achieved.
1. Hold down the [Online] and [Menu] keys, and turn on the printer. (This initiates
engine SP mode.)
2. Select “9: ID Sensor PWM” in the engine SP menu. Specify 150 as the PWM
value. Press the [Enter] key, then an asterisk (*) is displayed before the value.
Press the [Escape] or [Menu] key.
3. Select “7: Process Ctrl” in the engine SP menu. Execute “Color Bias.” (This
starts process control for the color development bias settings.) Wait until “Finish
OK” is displayed. Then press the [Escape] or [Menu] key.
4. Select “8: Test Print” in the engine SP menu. Execute “Pattern 3” to print
pattern 3. (Select a tray with paper in it.)
NOTE: Test printing is executed continuously. To stop test printing, press the
[Escape] or [Menu] key.
5. Check the test print. If the YCM solid areas of the printed image are too dark,
return to step 2 and increase the PWM value by one. If the YCM solid areas are
too pale, return to step 2 and decrease the PWM value by one. Then, repeat
steps 3 to 5.
6. If the YCM solid area density is good, select “7: Process Ctrl” in the engine SP
menu and execute “Initialize.” (This executes a complete forced process control
self-check.)
7. After the forced process control self-check is completed, restart the printer in
normal mode.
