Note: A valid BPNOTE: A valid BPX username and password may be required to view the okiDoc via the link above.OverviewThe sensitivity of the micro-displacement sensor used as the media thickness detector are notuniform in detection sensitivity. To learn the sensitivity of that unit’s sensor beforehand, there is aneed to pass a media source with a priorly known thickness through the detector. The sensitivityshall then be detected based on the output value of the sensor.Adjustments are necessary when replacing the Paper Thickness Sensor, Resist Roller and PUPCB.Prepare four media sources with a thickness already measured with a micrometer (MDQ-30M,MDQ-30). Then pass those sheets through the MP Tray. The media thickness sensitivitycorrection value is automatically set with the 3 sheets. Then the media thickness detectionvalue is tested with the 4th sheet.Media Used : Transparency Sheet (42527801)Paper Thickness Detection Error : ±10μm or lessPress Triangle ( ) Buttonuntil Panel Display Is:Diagnostics modePress the triangle ( )a few times.Panel DisplayPress Enter.Press the triangle ( ) a few times.Press Enter.Use Precision Screwdriver (Flathead) toTurn Adjustment Screw to Adjust Value toRange FAh to 15Eh (Target 12C (Hex)).Turn Off Printer.Check Panel Display Is: DisplayDisplay4=***Weight sensor output displayedat three asterisks [***].Value changed by turning adjustment screw.REG L/R xxx WEIGHT1=*** 2=*** 3=*** 4=***SWITCH SCANZero Point Value
