HL-3400C SERVICE MANUAL 6) Re-enter the FU UNIT (NC8) value as follows; i) Enter the value of NC8 - LP8 into the TOTAL PAGE counter. (i.e.) NC8 - LP8 = 39,684 - 70,000 = - 30,316 Since the above result is minus, reduce the value of LP8 is 30,000P in order to make the result plus, then enter it into the LIFE PERIOD SET counter in FACTORY MODE. The formula is as follows; NC8 - LP8 = 39,684 - 30,000 = 9,684 Enter the value `9,684' in TOTAL PAGE. ii) Perform CLEAR CARE 8. (Refer to '36 CLEAR CARE' in page V-24 of Chapter V.) iii) Check that the value of NEXT CARE is reset correctly. (i.e.) NC8 = 39,684P iv) Reset the LIFE PERIOD counter in FACTORY MODE to 60,100. 7) Re-enter the 240K KIT (NC10) value as follows; i) Enter the value of NC10 - LP10 into the TOTAL PAGE counter. (i.e.) NC9 - LP9 = 120,000 - 120,000 = 0 Enter the value '0' into the TOTAL PAGE counter. ii) Perform CLEAR CARE 9. (Refer to '36 CLEAR CARE' in page V-24 of Chapter V.) iii) Check that the value of NEXT CARE is reset correctly. (i.e.) NC10 = 120,000P 8) Re-enter the original TOTAL PAGE (T) value in TOTAL PAGE SET in FACTORY MODE. (i.e.) T = 412P 9) Re-enter the original EACH IMAGE (IY, IM, IC, IK) values in EACH IMAGE SET in FACTORY MODE. (i.e.) (IY)=348P, (IM)=353P, (IC)=365P, (IK)=439P 10) Ensure that the values in the LIFE PERIOD SET counters in FACTORY MODE are correct. (i.e.) FC ROLL (LP2)=12,000P BL UNIT (LP7)=50,000P FU UNIT (LP8)=60,100P 120K KIT (LP10)=120,000P 11) Completed. A-13
