Go to FIP1.20.2 Checking the TRANSFER ASSY for installationIs the TRANSFER ASSY installed correctly? Go to step 4.Reseat theTRANSFERASSY, then go tostep 3.3 Does the error still occur when the power is turned ON? Go to step 4. End of work4Checking the toner densityIs there the dark color? Compare the density of four colorstoner.Checked by [Test Print] - [Gradation] in diagnosis.Go to step 5.Replace thePWBA MCU.(Refer to Removal30/Replacement14)5Checking the solenoid in the TRANSFER ASSY for opera-tionDoes the ADC Sensor operate normally?Checked by [Digital Output] - [DO-37(Control Panel)/CTDSOLENOID ON(PC)] in diagnosis.Replace the cor-responding CAR-TRIDGE ASSY.(Refer to Removal6/Replacement38)Go to step 6.6Checking the connectors for connectionCheck the connections between the PWBA MCU andTRANSFER ASSY.Are P/J27, P/J272 and P/J2721 connected surely?Go to step 7.Reconnect theconnector(s)P/J27, P/J272and/or P/J2721surely,then go to step 7.7Checking the HARNESS ASSY FRONT COVER for conti-nuityDisconnect P/J2721 from the TRANSFER ASSY.Disconnect P/J272 from the HARN ASSY R SIDE.Is each cable of P/J2721 <=> P/J272 continuous?Go to step 8.Replace the HAR-NESS ASSYFRONT COVER.8Checking the HARN ASSY R SIDE for continuityDisconnect P/J27 from the PWBA MCU.Disconnect P/J272 from the HARNESS ASSY FRONTCOVER.Is each cable of P/J27 <=> P/J272 continuous?Go to step 9.Replace theHARN ASSY RSIDE.
