Chapter 1414-214.1.4 After Replacing the Reader Controller PCB 0014-3115Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 /Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080i / iRC2550- Before replacing the reader controller PCB, be sure to generate the latestP-PRINT printout.- If you carry out the power ON and the copier returns to the standbycondition after the controller circuit PCB replacement, turn ON/OFF thepower supply once again.the PCB>- Using the SST, upload the reader controller backup data; afterinitializing the RAM, download the data, thus eliminating the need for thefollowing adjustment.1. Reader Unit-Related Adjustment1) Using the SST, download the latest system software (R-CON).2) Make the following selections in service mode: COPIER>FUNC-TION>CLEAR>R-CON; then, press the OK key to initialize the RAM.Thereafter, turn off and then on the main power.3) Enter the appropriate values using the following service mode items:a. standard white plate white level dataCOPIER>ADJUST>CCD>W-PLT-X,Y,Zb. offset value against color displacement for copyboard glass (copyboardcover)COPIER>ADJUST>CCD>BOOK-RGc. offset value against color displacement for copyboard glass (ADF)COPIER>ADJUST>CCD>DF-RGF-14-5d. service label (behind reader unit left cover) valuesd-1.

ADF-Related AdjustmentThe machine keeps ADF-related service mode data in the RAM of the readercontroller; as such, you will have to make the appropriate adjustments if youhave replaced the reader controller or initialized the RAM.1) Enter the values indicated in the P-PRINT printout you have previouslygenerated for the following:a. main scanning direction position adjustment (stream reading)COPIER>ADJSUT>ADJ-XY>ADJ-Y-DFb. original stop position adjustmentFEEDER>ADJSUT>DOCSTc. original feed speed (magnification) adjustmentFEEDER>ADUST>LA-SPEED2) Make adjustments using the following items:a. tray width adjustmentFEEDER>FUNCTION>TRY-A4FEEDER>FUNCTION>TRY-A5RFEEDER>FUNCTION>TRY-LTRFEEDER>FUNCTION>TRY-LTRRb.
