Check the Zero point output of Media Thickness Sensor in advance.Display the Paper thickness sensor output with 5.3.2.3 Switch Scan test.Remove all papers at paper feed route as of now.Check paper thickness sensor output is 260h to 300h or not.If out of range, carry out a Zero point adjustment of Media Thickness Sensor.For the adjustment, four sheets of a media whose Thickness(It is more desirable for measureby micrometer) has been specified in advance are required. (Three sheets are required forthe adjustment and one sheet is required for the check after the adjustment.)Media to be used and setting valuesNo. TypeMedia Thicknesssetting value(Default)Number of sheets(Default) Remarks1 Media for sensitivity correction 6EH (110 μ m) 32 Media for checking 6EH (110 μ m) 1The thickness of typify is refer to the following table.Paper thickness change by lot and environment so that recommend to measure bymicrometer.MedianameOKI dataexcellentwhiteOKI dataexcellent white(Thick)Data Copy HAMMERMILL24lbMondiColor Copy1003M CG3600(OHP)size A4 A4 A4 LT A4 A4Thickness( )90 115 105 104 104 104In order to execute this adjustment (MEDIA WT ADJUST PA), stack the above media in orderin advance (No.1 and No.2 in order from the above four sheets in total) and then set themedia on MPT.
