Go to step 2. End of work. *12Checking after reseating the PHD UNIT and TONERCARTRIDGEsReseat the PHD UNIT and four TONER CARTRIDGEs.Does the error still occur when the power is turned OFF andON?Go to step 3. End of work. *13Checking after reseating the PWBA MCUReseat the PWBA MCU.Does the error still occur when the power is turned OFF andON?Go to step 4. End of work. *14Checking the connectors for connectionAre the following connectors connected correctly?- P/J311 on the Toner CRUM (Y)- P/J312 on the Toner CRUM (M)- P/J313 on the Toner CRUM (C)- P/J314 on the Toner CRUM (K)- P/J31 on the PWBA MCU- P/J42 on the PWBA MCU- P/J144 on the PWBA EEPROM (XPRO)- P/J422 on the PHD UNITGo to step 6.Reconnect theconnector(s) P/J311 to P/J314, P/J31, P/J42, P/J144 and/or P/J422 correctly,then go to step 5.5 Does the error still occur when the power is turned OFF andON? Go to step 6. End of work.Mnt01004KAP/J314P/J313P/J312P/J311P/J31P/J144P/J42P/J422
